Hello,

I am a full stack web developer and I have been thinking about creating web application that would show live wind speed and direction data.

My motiviation is : 1. I am kind of bored with building typicall web applications and would want to make something more connected to the real world

2. I am a big fan of water wind-driven sports and would love to see such a application

Maybe it would be possible to make use of your anemometer in a project like this? If I installed a few of these myself in a few spots and launched an application that would collect the data and present it in a nice way then maybe people would order these and install them themselves and the coverage would grow. I can see adding a new device to the existing network effortless which would be a key part for people to participate. Some concerns that i see are power supply and internet connectivity but if simply connecting the device to the electicity would not be an option on some site then maybe it could run on a battery + solar panel? The other thing is network connection which could either be wifi or 3g.

Please let me know what you think of this idea. Maybe we could work together.

Kind regards, Andrzej Swaton

Giorgio Picanco 31 July 2016

Hello! I’m Giorgio.

I am a Brazilian student and i’m writing because I intend to execute your anemometer project for teaching purposes at my college. I saw three possibilities to be realized: the anemometer with separate analog and digital circuits, the anemometer standalone and a shield for Arduino. What do you recommend I do? I want to do something quick and easy, because I have no knowledge in electronics, but I want something functional to be able to teach meteorology to children. Sorry for my bad english . Here only we speak Portuguese.

Best regards!

Victor 22 August 2016

Hello Lukas!

Thank you for building the useful things. I looks a forward to order the Ultrasonic Anemometer Rev B Board (perhaps three pieces). In my plans are using your anemometer together with Murata Ultrasonic Transducers MA40H1S-R (I have 12 pieces). Or maybe you will support Ultrasonic Anemometer Board with other transducers (maybe water proof)? In my plans is using Anemometer Board together with Arduino and Raspberry PI as mobile and networking weather station. You solution is perfectly supported my needs. Also I want add to your code a function to calculate a wind direction using this simple formula:

int Dwind = 57.3*atan2(NS_wind, -WE_wind) + 270.0; // 270 (West quadrant, or other angle) moves result into compass

Hope this will be calculate a wind direction successfully.

Also I would like order the one Bi-Directional Voltage Level Translator for my future projects. Can you send me instructions how I can make an order?

Sorry for my bad English.

Peter Donker 28 August 2016

Hi Lukas,

Great stuff with the anemometer. I am a paragliding pilot and decent anemometers are very expensive and often not all that good. This looks like a potential solution for us. We have very bad experiences with “classic” models because they break on top of our mountain. I’d love to see if it would be possible to build an autonomous weather station with your design for anemometer. I’d love to know when you could have kits available so that I can try this. And please let me know if you find such a project interesting to participate in.

Thanks,

Peter Donker Club Albatros

Bjorn Pehrson 4 September 2016
I am not sure about how to order the anemometer kits. I would like to include the sensors. If you can sapre more than one, fine butat least one. How do I pay? Bjorn
Bjorn Pehrson 6 September 2016
Hi Lucas, If the queue for your kits is not overwhelmomg, I would love to get two kits. Iwould like to work with ne myslef and I found a couple of students that I would like to get involved. Please tell me how many I can get and also how to pay. Thanks Bjorn
Robert Jaryczewski 11 September 2016

Dear Lukas,

I’ve followed your progress with the Ultrasonic Anemometer since the early days. If you still have a kit available, I’d like to buy one complete with the transducers. Please let me know the procedure.

Best regards, Robert

Josh Kelfer 19 September 2016

Kevin Mahler 16 October 2016

I’d like to order one of your ultrasonic wind speed/dir kits with transducers. I’m in the US so as I read your site, it’s $95 USD delivered. If that’s not correct, please let me know. How would you like to be paid? Do you have them available to ship in a reasonable length of time? I’m in no rush but would like to have it in hand within 3 or so weeks.

Thanks, Kevin kmahler@kmahler.com

Andy Froncioni 19 October 2016

Lei Tao 1 November 2016

Hi Lukas:

I would like to buy one of your sonic anemometer kit without transducers for some test. How can I pay you? PayPal?

I also have a few questions: 1. What was the precision in your test for wind speed? 2. For the transducers, how far apart can I separate them? Is it possible to do a few meter? 3. Can I use only one pair of transducers with these board for one direction measurement? I have never program a PIC chip before. Is it hard to a newbie? 4. I want to use some transducer for erosive environment(may be ceramic one). Do you have any recommendation? I should get these 40 KHz ones, right?

Thank you and looking forward to your reply. Lei

Jim Schuelke 10 November 2016

Lukas,

I’m very interested in your ultrasonic anemometer project but am new to Microchip, MPlab and Harmony so I’m not sure how to create a project from your source code. I don’t see a project file (.mcp). Do I create a new Harmony project and add all your sources individually? Any help would be appreciated. Thanks in advance, Jim

Peter 21 November 2016

Hi there Lukas,

Have been following your product of and on with interest. Kinda missed you developing the new hardware kit which interests me greatly.

Are you still taking orders for your aneometer kit? I was planning on assembling one thogether with a friend (he the soldering and me for the software)

Regards

Peter Kaagman

Erik 30 November 2016
Hi Lukas, I’ve just commented on your ultrasonic anemometer project, it’s just a great project! Just a few clarificatory lines. I think that it’s possible for us (Basicairdata team, open and free project) to support your project under many aspects. In fact, we probably already dealt with many of the aspects you are facing with probe design and test. You can send email directly to me at erik@basicairdata.eu. Thank you again for sharing! Erik
Christian Fetzer 31 December 2016

Hi Lukas,

I’m really impressed by your work on the ultrasonic anemometer. Since I love to play with electronics as well, I’d like to ask if you still have a kit left for ordering (with transducers).

Thanks much, Christian

Vincent FROLLI 24 January 2017

Hi,

I would like to know if you still have some ultrasonic anemometer kit in stock and if so how we can proceed to buy one.

Taylor Thomas 31 January 2017

Hello -

I’m very interested to be able to learn more about the work that you’ve done! My background is in micrometeorology and I have fairly extensive experience testing these types of instruments (http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1130&context=natresdiss).

I think there’s tremendous potential to be able to better understand our world with low-cost, open source ultrasonic anemometers and I’d love to contribute to this project however I can. If you have some interest in this, perhaps we could set up a time to talk or perhaps I could purchase a kit from you. This would just be a personal (hobby) project for me. I’m located in the US (east coast).

Thanks a lot and truly great work! Taylor

Colin Lloyd 28 February 2017
With regard to your excellent series on creating an Ultrasonic Anemometer: As a co-developer of battery-powered sonic anemometers for use in energy balance studies back in the 1970’s (see Lloyd et al. 1984. A Microprocessor System for Eddy-Correlation. Agricultural and Forest Meteorology 33: 67-80), I’d like to know more about your operational objectives for your sonic anemometer i.e. where you thought the application might be used. I noted somewhere in your progress series that you were aiming at measurements of 4 Hz. While this is OK for measurement of general windspeed, it is a very low frequency for analysing wind vectors of small eddies. I’m not an electronics expert - so I would like to know whether the anemometer transducers and associated electronics could be “pushed” to frequencies of 10Hz or even 20 Hz?
paolo marotta 30 March 2017
Hi, wanted to know if you can buy the kit anemometer Arduino. thanks
Bobb 31 March 2017

I just came across you article on the Ultrasonic Anemometer. I had been looking at the new Adafruit ToF modules, wondering if I could use them to try and build one myself. Have you seen these devices and do you think them might be usable?

Thanks,

Bobb

Manfred Koehler 3 April 2017

Hello Lukas, I have enthusiastically followed your blog about the ultrasonic anemometer for the Arduino. I’ve seen you have a kit. Is it possible to order this kit now? If yes, please give me the price (with transductors) and the transfer charges. How long does delivery take?

Greetings from Germany

Echa 7 April 2017

Hello Lukas,

Greetings from Tokyo.

I am Echa, student from Tokyo Institute of Technology. And I am interested in developing sensor kit to measure acoustic temperature using transducer for mobile measurement of temperature.

Your standalone ultrasonic-anemometer (including the downsized version) is really awesome! I want to try to use your kit. Is it possible for shipping from swiss to Tokyo-Japan?

Thank you and looking forward to your reply.

Best regards, Echa

Dan 6 May 2017

Hi Lukas,

(Sorry if this got posted multiple times - I can’t tell if it submitted properly).

I have built up a few of the boards using your files and BOM, and I’m seeing some weird behavior. When I apply 12V, the board immediately begins drawing the max current I have my supply set to, about 1A. Same thing happens when I power the 3.3V rail, it slowly ramps up to full current.

Any suggestions on how to remedy this?

Thanks! Dan

Dale Chatham 21 May 2017

Stanislav Velchev 10 June 2017

Hello Lukas! I’m a paragliding pilot from Bulgaria. So for our needs having a reliable anemometer at the take-off places is essential for picking up the best place for the day, saving us tens of km’s driving.

Just as you I was inspired by the Karl’s project and started doing my own version of the project to satisfy the club needs for a reliable anemometer. We have used number of cup anemometers but they all fail in about of year. Usually the winter is killing them. That’s why I have started the ultrasonic project.

I’m facing number of difficulties that I can not resolve with my current knowledge and equipment. Considering the time constraints I’m about to suspend the project for until some time in the future when I have the needed resources.

So here your project comes into place! Here are some questions: - Are you still offering kits? - Do they work reliably with waterproof sensors? - Have you put a complete kit in real world outdoor testing?

I’m interested in getting a full kit (with sensors). I will build the required housing and mounting. If we have a success with deploying one kit on top of our plateau here in Shumen for sure we will be interested in getting few more kits and deploy them around the country.

I hope I’ll be able to help with testing, providing feedback etc.

Congrats for the great passion and level of details you put in your projects. Really inspiring! :)

Cheers, Stanislav

Ryan Roppel 10 August 2017

Hi Lukas,

I was wondering if you had any more of the anemometer boards with the transducers for sale? I was reading through your site and is just perfect for my weather station project I was working on. Please let me know how I can submit payment. I’m located near Pittsburgh, PA.

Thanks!

Nicolás Rodríguez 12 August 2017
Dear Lukas, Your anemometer project is excellent, congratulation! I’m writing to you from Colombia and I would like to make one for outdoor purposes. Do you have the pcb for selling? it will solve me a big headache! In my case due to the difficulty to get all the components for the pcb’s as your design indicates and my limitation to assembly it, I’ll have to change most of them by “through hole” components. Does it exist any failure possibilitie doing this changes? Best Regards Nicolás
Andro 20 September 2017

Hello Lukas, Thank you so much for sharing the ULTRASONIC ANEMOMETER project with the world. You are helping make the world a better place. One question, I have bought the kit and I’m trying to duplicate your project. I’ve soldiered everything according to the schematics, and now I’ve been trying to get the software to work. Everytime I compile the code, I get the error: ../src/system_config/PIC32MX250_RevA/system_definitions.h:53:38: fatal error: system/common/sys_common.h: No such file or directory #include “system/common/sys_common.h” It seems like you used a library which you did not include on the git repository. Which library did you use for these files? I would really appreciate any help. Thank you so much, and looking forward to talking to you.

Best, Andro Nooh

My daughter needs a portable ultrasonic anemometer for a school project, which i think you have here. Are you ready to ship to the Philippines on an expedited (5-day) shipping? Thanks.
Vishal Deo 11 January 2018

Hi Lukas

I have being reading you post on ARDUINO ULTRASONIC ANEMOMETER. I want to try and make this project.

Can I purchase a kit from you along with the programs. And how can I do that ?

Please email me the cost and how to pay.

Pierre Fischer 29 April 2018

Hello Lukas, I am French, I live in Lyon. First of all, thank you for your great work, and all the time you spent for giving us this blog. Are you still selling anemometer kits ? The kit with transducers comes with waterproof ones, for outdoor use ? Do you sell the stainless steel stencil, for applying solder paste ? I have a T-937 reflow oven.

I plan to use your anemometer with an ESP32 as “central” microcontroller. I will download your software, to see how I can interface it with SPI or I2C.

PIC32 MCU is a very good choice ! Thank you !

Please tell me how to send payment (Paypal ?), of course if you are still selling kits…

I am sorry to take much of your time with all my questions…

Best regards

William Thielicke 7 September 2018

Hallo Lukas, direkt zur Sache…: Mein Name ist William, und ich arbeite in einer Firma die den 3D Windvektor von einem Multikopter heraus messen möchte. Dazu möchten wir gerne einen US Sensor einsetzen. Kommerzielle Sensoren sind entweder zu schwer (1 kg), oder bieten kein “echtes 3D”. Im Prinzip könnten wir auch drei getrennte 1D Sensoren aufbauen. Wir suchen einen Sensor der uns “einfach nur” die drei Geschwindigkeitskomponenten per UART oder I²C ausspuckt, mit mindestens 10 Hz. Ich habe gesehen, dass du ein wunderschönes Projekt zu einem 2D Sensor hast. Hast du eine Idee zur Präzision des Sensors? Wäre das wohl prinzipiell für unser Anliegen einsetzbar?

Danke für deine Antwort & viele Grüße aus Lörrach, William

Sukhraj Hothi 16 October 2018

I have been interested in caves all my life. I’m 68 now and a retired electrical person… I have often thaught it would be great and useful to be able to record airflow through cave systems as a guide as to where the cave continues . new cave passage. Collected data from moniters in the cave could be loaded into a GIS program such as MapInfo then the changes in direction and flow displayed real time…it would be a great guide to locating new cave.

Your Anemometer seem to fit my need. Is there any way to get some sort of finished or kits or some kind some assistant.

Sincerely,

Michael Xynidis 25 April 2019
Dear Mr. Faessler, I am writing from the University of Central Florida (UCF) to tell you that we are quite impressed with the work you’ve published thus far on soldernerd.com. In fact, a team of graduate students have attempted an implementation using 3-D printed structures, but substituting an adafruit huzzah(ESP32) in place of an arduino so that wind data can be streamed via MQTT protocols to IBM Node-Red for visualization and further analysis/processing. However, we are having some problems. I am hopeful that we can enter a dialog with you for troubleshooting advice. We have diagnostic equipment, a prototype facility and three boards that we cant seem to operate correctly. All return values on both HID and I2C, but the values dont seem to make sense and are unstable. We can send you output data and pictures - in fact we can even send you over a board or two we’ve built. Would you be willing to help? Respectfully, Dr. Michael Xynidis, PD3D Lab, UCF
scott slesser 26 June 2019
Hi, Can you let me know the current status of the ultrasonic anemometer project/board? I notice the last posts were from 2017? We’re trying to put together a model boat with an integrated DP system and a Wind sensor is one of the major inputs required. Our project is currently based on using the R.Pi, so we could use the SPI interface? Thanks for any info!

Hi I just wanted to know if I can order your ultrasonic anemometer and how ? Why didn’t you put it on Kickstarter or Amazon ? you can add a temperature sensor and a light sensor and you have a meteo station ! I have seen some manufacturer selling it for $500-$800 and I’m wondering if they are greedy or not, and if people buy it. Thanks
Nicolas Martin 21 December 2019

Hi Lucas,

I am looking into using a convenient IC to output a burst of40kHz PWM pulses every 20 milliseconds. I have seen that you have done a similar thing using the PIC16F1936 for the ULTRASONIC ANEMOMETER. However I could not find the code you have used to generate this PWM.

Could you please help me with this. My email address is king_chichkhan@hotmail.com.

All the best

Stephen Calvert 24 March 2020
I’m retired now. I was an electronic repair man and then radio planner . But my interest is caves since being a tenager in UK . There is still one large cave system in UK to enter and explore . The upper reaches can be accessed but the geology does not access to the lower chambers . The cave has a draft flowing into it subject to surface air pressure. It fill up in nice high pressure weather. If the air flow could be recorded in various passages in the known system . Collected data could be mapped which would indicate areas to continue exploring in order to gain access to the large chambers lower in the cave. Your equipment would be ideal for this logging.
Chris 22 October 2020

Greeting Lukas,

I am Chris and is a newbie in electronic. Please please help me to solve my confusion. Currently, I’m working on an ultrasonic anemometer project which I have deep confusion when looking at your post. How is the Tof is being measured? So when the signal being received and triggered the envelope detector that’s the estimated Tof right? (That one pretty straightforward to me)What I confused about is how’s the ZCD can helps in determined the phase shift… I had looked at post no.8 that you save the value of the timer1 when rising and falling on the ZCD. So that would give us a total of 8 cycles of the signal right(which I think is 8*25us is that true?)

“Averaging these will give us a very precise measurement of the phase shift.” –> This is the confusing part for me… I just don’t get how is the phase shift being calculated. So we have 16 value of the ZCD value, each is 180 degree to each other? I’m just too confused…

Also how you overcome the issue from blocking the noise at 40kHz? If there’s 40kHz noise, then will the analog circuit treat it as the signal being sent then causing wrong calculation?

P.S I got looked a bit into the project report from Carl one. His method I think is adding numbers of 25us periods + the phase shift. What I didn’t understand was how the ZCD helps in the phase shift. And does his method is the same as yours? Hoping for your reply, it would really save my world.

Regards, Chris

Rob Bolton 30 November 2020

Hi Lukas,

I hope you’re well. I’m getting in touch having found (and been fascinated by) your blog posts about the ultrasonic anemometer you developed. It’s a really impressive project.

I’m interested in it because I’m currently working on an

\[Arduino based\]

environmental monitoring project and adding wind speed measurement to it would be useful. I saw in the later posts that you got as far as doing a small initial run of your Rev B standalone boards and testing with weatherproof transducers. You discuss wanting to make further additions to the USB side (MSD interface/bootloader); but I wonder if (aside from those extra features) the core software for measuring wind speed is functional?

I imagine your initial run of boards is exhausted by now; do you plan to do another run, or if not would it be possible/acceptable for me to get my own made up to your design?

Thanks and best regards,

Rob.

Francesco Rossi Lena 22 December 2020

Hello Lukas! Congratulations for all your amazing projects. I’m very interested into your ultrasonic kit and would like to know if you can ship one to Brazil. By now I need only one kit but probably will need more in the future. Could you send the waterproof version of the transducers? (MCUSD14A40S09RS) Do you accept paypal? My address is:

Hi !

I’m really interested in building an ultrasonic anemometer. Seeing that your last posts are from 2017 I guess that you stopped working on this project. I’m struggling at finding similar recent projects as detailed.

If you have heard of any would you let me know? Are you aware of any initiative trying to update your work?

Thanks,

Guilherme Chiang 28 May 2021

Hello!

I’m Guilherme Chiang, student of Control and Automation Engineering at UNICAMP, at Brazil.

I am responsible for the electrical project of Urubus Aerodesign Team, an extracurricular of aeronautical projects from the Faculty of Mechanical Engineering at UNICAMP.

I read about your ultrasonic anenometer project and I was interested to implement it iat our weather station. There’s a lot of information on your site and I get lost on the important information, so i have some questions.

1. I don’t know much about pic controllers and I get confused on how to upload the code to the PIC microcontroller.

2. How to calibrate the ultrasonic sensor and where to update the values to get the correct measurement.

3. The distance between the sensors are the same as the ultrasonic anenometer on hackaday?

Good Day Lukas- I realize that your Ultrasonic Anemometer project is about 4 years old, but I have just come across it and it fits our needs exactly; a remote mountaintop ham radio repeater site that is “eating” wind generators to the tune of $30K so far. I am having trouble downloading the BOM and DirtyPCB files from Github, for example the BOM is only 25kb and incomplete. Any chance there are kits still available? Cheers, Jay.

Hallo Lukas, ich interessiere mich für deinen Ultraschall-Windmesser - vermutlich ein Nachbar von mir auch - daher die Frage, ob Du für ein paar Fragen, evtl. sogar ein fertiges Board zu sprechen bist.

Grüße Stefan

Hello Lukas;

Your ultrasonic anemometer project looks beautiful. I have a few questions I want to ask you. In some projects, the sensors are facing each other, in some projects, the sensors are on a horizontal plane. Can I position the sensors horizontally in your project? Can you help me with this? Is there an e-mail address where I can reach you? I can explain the situation to you with pictures.

Thanks.
