Product details

The AHT20 is a cost-effective and user-friendly temperature and humidity sensor developed by the creators of the DHT22. It provides precise measurements of humidity with a typical accuracy of ±2% and temperature with ±0.3 °C in the range of 20-80% RH and 20-60 °C. The sensor uses the standard I2C interface, making it easy to integrate with various microcontrollers like Arduino or Raspberry Pi. The breakout board is equipped with the necessary support circuitry to simplify handling. Thanks to compatibility with the STEMMA QT system, users can connect the sensor without soldering and start using it immediately. A learning guide with schematics and libraries is available to help users get started.

  • High accuracy of ±2% relative humidity and ±0.3 °C temperature
  • Easy integration via standard I2C interface
  • Compatible with STEMMA QT for simple connection without soldering
  • Includes a learning guide with schematics and libraries.
