Hi, I want to be able to measure the relatively low airspeeds (0-10 meters/second) encountered on UAVs and para-gliders. I’ve looked at three ways of doing this... Differential pressure sensors – these seem to be fine for measuring airspeeds faster than 30-60 m/s, but at the speeds I’m interested…

Measuring low airspeeds

you could always use an ultrasonic transmitter/receiver pair
