Infineon Technologies DPS368 Digital XENSIV™ Barometric Pressure Sensor

Infineon Technologies DPS368 Digital XENSIV™ Barometric Pressure Sensor is designed to be robust against water, dust, and humidity in harsh environments. The sensor offers high accuracy and low current consumption and measures both pressure and temperature. The pressure sensor element is based on a capacitive sensing principle that provides high precision during temperature changes. The internal signal processor converts the output from the pressure and temperature sensor elements to 24-bit results. Infineon Technologies DPS368 Digital XENSIV™ Barometric Pressure Sensor is offered in a compact RoHS-compliant package, making it ideal for mobile applications and wearable devices.
