Micro airspeed meters were developed for Micro Aerial Vehicles that are small, light, and low power. The micro airspeed meter includes a micro pitot tube and a low-speed-measuring circuit based on a micro electromechanical systems (MEMS) differential pressure meter. An integral computer is used to measure the voltage from the pressure meter and calculate the airspeed. The measurement range is 3-26 m/s, the mass is 4.3 g and the precision is ±1 m/s. The micro airspeed meter has been successfully used on unmanned aerial vehicles with wingspans less than 400 mm.
