Barometric Pressure Sensor
Gigadevice barometric pressure sensor is based on MEMS technology to process cavities on silicon wafers. Using the wheatstone bridge principle, the output voltage at both ends of the bridge arm is proportional to the applied pressure. After temperature compensation calibration and algorithm processing, the output pressure and height values are obtained, providing a perfect solution for fields such as mobile phone, wearable, and IoT.
