Würth Elektronik WSEN-PADS Absolute Pressure Sensor

Würth Elektronik WSEN-PADS Absolute Pressure Sensor is based on the MEMS-based piezo-resistive sensing principle and offers 24-bit pressure output resolution. This pressure sensor includes a pressure sensing cell and an analog and digital signal processing unit. The WSEN-PADS sensor comprises a 128-level embedded FIFO buffer to store the pressure and temperature data. This pressure sensor also features an embedded temperature sensor and an I2C digital communication interface. The WSEN-PADS sensor operates at a temperature range of -40°C to +85°C. This pressure sensor offers a 1Hz to 200Hz output data rate, 26kPa to 126kPa absolute pressure range, and consumes a low current of up to 4μA. Würth WSEN-PADS sensor is ideal for use in weather stations, altimeters and barometers, GPS navigation, white goods, and wearable devices.
