Arduino-compatible board integrates five environmental sensors

Integrating five environmental sensors from TE Connectivity on an Arduino/Genuino 101 and Uno-R3-compatible board, the MEAS weather shield is now available from distributor Mouser.

The shield provides the necessary hardware to interface the TE HTU21D digital relative humidity sensor, MS5637 digital barometric pressure sensor, TSYS01 temperature system sensor, MS8607 digital relative humidity and digital pressure sensor, and TSD305-1C55 digital thermopile sensor. Arduino/Genuino-compatible headers for I2C communication are also included for a board offering a 64-pad prototyping area for soldering external devices.

The HTU21D self-contained humidity and temperature sensor has selectable resolution that measures relative humidity (RH) from 0 to 100 per cent and temperature from -40 to +125 degrees C. The MS5637 includes a high-linearity pressure sensor that measures pressure from 300 to 1,200mbar, as well as a low power, 24bit ADC with internal factory-calibrated coefficients.

The TSYS01 temperature system sensor combines a temperature-sensing chip and a 24bit ADC. It has a low power standby mode and a measurement range of -40 to +125 degrees C with accuracy from 0.1 to 0.5 degrees C.

The MS8607 pressure, humidity and temperature sensor is for use in weather station applications embedded into compact devices. It offers an extended pressure range of 10 to 2,000mbar.

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