AHT20 and BMP280 digital temperature, humidity and air pressure sensor

This compact module combines an AHT20 air temperature and humidity sensor with a BMP280 air pressure sensor to give you a comprehensive picture of the air conditions in your environment. The AHT20 and the BMP280 are widely used and popular thanks 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.
