Arduino-Compatible shield integrates five environmental sensors

In addition to Arduino/Genuino-compatible headers for I²C communication, the board offers a 64-pad prototyping area for soldering external devices.

The HTU21D sensor is a self-contained humidity and temperature sensor with selectable resolution that measures relative humidity (RH) from 0 to 100 percent and temperature from minus 40 up to 125 degrees Celsius.

The MS5637 pressure and temperature sensor includes a high-linearity pressure sensor that measures pressure from 300 mbar to 1200 mbar, as well as an ultra-low power 24 bit analog-to-digital converter (ADC) with internal factory-calibrated coefficients.

The TSY01 temperature system sensor combines a temperature-sensing chip and a 24-bit ADC, and features a low power stand-by mode for power-sensitive applications. It offers a measurement range of minus 40 up to 125 degrees Celsius with accuracy from 0.1 to 0.5 degrees Celsius.

The MS8607 pressure, humidity and temperature sensor is ideal for weather station applications embedded into compact devices, offering an extended pressure range of 10 to 2000 mbar.

The TSD305-1C55 is a contactless temperature measurement system that includes an infrared sensor (thermopile) and sensor signal conditioner. It measures temperature from 0 to +100 degrees Celsius with accuracy up to ±1 degree Celsius.
