Ultrasonic Anemometer

Antiath built his own ultrasonic anemometer.

This DIY project is based based on a Teensy 3.6. The teensy generates 40 kHz packets  and uses it’s own ADC ( after a two stage amplification) to measure the received packets and their time of flight between two ultrasonic transducers. The wind speed is directly deduced from the measured speed of sound.
