3DR Dual pressure CAN sensor - R0012 
Our new dual pressure sensor features All Sensors' AUAV barometer + differential air pressure 2-in-1 sensor.
Compared to the popular MS4525DO and DLVR airspeed sensors, the AUAV Series offers higher resolution, tighter accuracy, and much lower total error across temperature. It also integrates both differential and absolute pressure sensing in a single compact SMT module, reducing weight and simplifying system design while delivering more stable and precise airspeed and altitude data.
The AUAV series provides a total error band (TEB) of less than 0.65% over the compensated range of -30°C to +85°C.
This part includes a 4-pin JST-GH wire.
Optional pressure ranges, sensor types and pitot tubes are available upon request.
