HTU21D MEAS PI WEATHER SHIELD

2021-03-29
The MEAS Pi weather shield provides the necessary hardware to interface the HTU21D digital relative humidity sensor; MS5637 digital barometric pressure sensor; temperature system sensor (TSYS)01 digital temperature sensor; TSD305-1C55 digital thermopile sensor to any system that utilizes Raspberry Pi compatible expansion ports configurable for I²C communication.
The HTU21D sensor is a self-contained humidity and temperature sensor that is fully calibrated during manufacturing. The sensor can operate from 1.5V to 3.6V, has selectable resolution, low battery detection, and checksum capability. The HTU21D has a low power stand-by mode for power-sensitive applications.
The MS5637 sensor is a self-contained pressure and temperaturesensor that is fully calibrated during manufacturing. The sensor can operate from 1.5V to 3.6V. The sensor module includes a high-linearity pressure sensor and an ultra-low power 24-bits ΔΣ ADC with internal factory-calibrated coefficients.
The temperature system sensor -TSYS-01 series is a self-contained temperature sensor that is fully calibrated during manufacturing. The sensor can operate from 2.2V to 3.6V. The TSYS01 has a low power stand-by mode for power-sensitive applications.
The TSD305-1C55 is a contactless temperature measurement system located in a TO5 package. The TSD includes an infrared sensor (thermopile) and a sensor signal conditioner.
