Product Summary

The SDP3x sensor family is Sensirion’s series of small differential pressure sensors designed for high-volume applications

where size is a key requirement. It builds on the next generation CMOSens® sensor chip that is at the heart of Sensirion’s

new differential pressure and flow sensing platform.

The digital SDP3x sensor features fast measurement speed, excellent accuracy and long-term stability and has no zero-point

drift. Furthermore, it is reflow solderable and provides extended functionality, such as smart averaging, multiple temperature

compensation modes, configurable I2C address and interrupts.
