Ultrasonic Anemometer Part 30: Downsized Hardware
In my last post of this series I’ve looked at different transducers and finally decided on a entirely waterproof 14mm model. The much lower signal level from those kind of transducers makes it necessary to reduce the distance between the transducers in order to still receive a reasonable signal amplitude. So I took my previous lasercut design and reduced it in size so that the distance between the transducers is only 120mm. I went to the local FabLab and and lasered two copies of the downsized design.
