EchoUAS Sensirion SDP3x Airspeed Sensor Kit (SDP33)

The SDP3x sensor family is Sensirion's series of small differential pressure sensors designed for high-volume applications where size is a key requirement.

The digital SDP3x sensor features fast measurement speed, excellent accuracy, and long-term stability and has no zero-point drift. This module is reflow solderable and provides extended functionality, such as smart averaging, multiple temperature compensation modes, configurable I2C address, and interrupts. The airspeed is most effectively measured with a pitot tube and a differential pressure sensor.
