AHT20 and BMP280 environmental sensor module — front view

Product Description

The AHT20 + BMP280 Sensor Module combines two high-performance digital sensors to accurately measure temperature, relative humidity and atmospheric pressure in a compact module. Featuring the ASAIR AHT20 humidity and temperature sensor along with the Bosch BMP280 pressure sensor, it delivers reliable environmental monitoring through a standard I2C interface.

Operating from a 2.0V to 5V supply, the module offers low power consumption and fast communication, making it ideal for Arduino, ESP8266, ESP32, Raspberry Pi and other embedded platforms. It is well suited for weather stations, IoT devices, environmental monitoring, smart agriculture and home automation applications.
