Airspeed sensors estimates the air speed using a differential pressure sensor and a pitot tube. Pitot tube has two pipes, one for static pressure (side of tube) and other for dynamic pressure in front of tube. Two differential analog sensors are supported: MPXV7002DP and MPXV5004DP
Connections are pretty simple: Gnd, +5V and analog voltage proportional to the airspeed. Sensor can be connected in various ports, according to the board you use. See next part. |
