DPP904R000..

The DPP904R000 from Sensor Solutions - TE Connectivity is a MEAS Pi weather shield. It provides necessary hardware to interface HTU21D digital relative humidity sensor, MS5637 digital barometric pressure sensor, TSYS-01 temperature system sensor, TSD305-1C55 digital thermopile sensor to any system that utilizes Raspberry Pi compatible expansion ports configurable for I²C communication. The HTU21D is a self-contained humidity and temperature sensor that is fully calibrated during manufacturing and can operate from 1.5V to 3.6V has selectable resolution, low battery detection and checksum capability. The MS5637 is a self-contained pressure and temperature sensor that is fully calibrated during manufacturing and can operate from 1.5V to 3.6V. The temperature system sensor TSYS-01 series is a self-contained temperature sensor that is fully calibrated during manufacturing and can operate from 2.2V to 3.6V. The TSD305-1C55 is a contactless temperature measurement system in a TO5 package.
