Description

After the price for the popular BME280 went through the roof in early 2021, we were looking for an alternative and found this combination of ASAIR AHT20 sensor and Bosch BMP280 sensor chips extremely helpful for accurate readings of temperature, humidity and air pressure. It replaces BME280 with equivalent specs.

The module works on 3.3V and supports I2C bus speeds of 100-400kHz.

Measuring ranges AHT20
Temperature: -40 to 85C, accuracy 0.3C
Relative humidity: 0-100%, accuracy 2%

Measuring ranges BMP280
Temperature: -40 to 85C, accuracy 1.0C
Air pressure: 300-1100hPa, accuracy 1hPa

The I2C address for AHT20 is 0x38, for BMP280 it can be 0x76 or 0x77.
