Capteur de pression SDP33

The SDP33 is one of the smallest differential pressure sensors on the market, belonging to Sensirion’s tiny SDP3x sensor series.

Unlike standard piezoresistive pressure sensors that suffer from thermal drift and calibration offset issues at low pressures, the SDP33 uses a thermal CMOSens® flow channel to measure microscopic pressure differentials with phenomenal repeatability.

Whether you're building a Pitot tube airspeed system for an autonomous fixed-wing or VTOL drone, constructing an automated medical spirometer, or building an ultra-sensitive HVAC clogged-filter detector, the SDP33 gives you clean 16-bit pressure data over I²C without needing software-side zero calibration.
