The five sensors are: 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.

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 TSYS01 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.

The TSYS01 offers a measurement range of minus 40 up to 125 degrees Celsius with accuracy from 0.1 to 0.5 degrees Celsius. The MS8607pressure, 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 a sensor signal conditioner. The TSD305-1C55 measures temperature from 0 to +100 degrees Celsius with accuracy up to ±1 degree Celsius.

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