The Sensirion SDP810-125PA is a board-mountable pressure sensor tube connection and I2C communication interface with a pressure rating of 125Pa. It is able to measure precise absolute pressures, partial vacuum, and differential pressure values. This is especially useful in applications such as HVAC, medical, and industrial. It has a temperature range of -40°C to 85°C, and a high accuracy of 0.5% calibrated, 0.9% total error band. It is also equipped with an easy-to-use digital protocol with a standard 2-wire I2C interface. This makes the SDP810-125PA pressure sensor an ideal choice for many designs.
