Arduino Weather Shields

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 detect, and checksum capability. The HTU21D has a low power standby mode for power-sensitive applications. The MS5637 sensor is a self-contained pressure and temperature sensor 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 bit _Σ 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 MS8607 sensor is a self-contained pressure, humidity and temperature sensor that is fully calibrated during manufacturing. The sensor can operate from 1.5V to 3.6V. The MS8607 is ideal for weather station applications embedded into compact devices and any applications in which pressure, humidity and temperature monitoring is required. 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.
