Purecrea AHT20 and BMP280 digital temperature, humidity and barometric pressure sensor

This compact module combines an AHT20 air temperature and humidity sensor with a BMP280 air pressure sensor to provide you with a comprehensive picture of the air conditions in your environment. The AHT20 and BMP280 are widely used and popular due to their precision and compact size. Communication is conveniently done via the I2C interface with a microcontroller of your choice, thanks to the operating voltage of 2-5V.
