Reliable and Compact

I bought five of these for a greenhouse monitoring project. All units are consistent with each other. The combination of AHT20 and BMP280 on one board saves a lot of space in my enclosure.

Great value, minor soldering needed

The sensor works great out of the box. I deducted one star because the headers were not pre-soldered, so you need to do a little work before using it on a breadboard. Otherwise, precision is impressive for the price.

Perfect for Weather Stations

This module is exactly what I needed for my DIY weather station. The I2C communication is stable, and the data from both sensors matches my reference equipment very closely. Easy to wire up with an ESP32.

Solid performance

Good accuracy for general environmental monitoring. Note that the pressure reading needs calibration based on your altitude for absolute accuracy, but relative changes are spot on.

Exceeded expectations

Very fast response time compared to older DHT11 modules I have used. The build quality feels robust, and the PCB layout is clean. Will buy again for future projects.

Easy library support

Found libraries for both sensors immediately for Arduino. Had it reading temperature, humidity, and pressure within 20 minutes of unboxing. Highly recommended for beginners.

5 FAQ

Q: Can I use this outdoors directly?

A: While the sensors themselves are robust, the PCB is not waterproof. For outdoor use, please house the module in a ventilated, weather-proof enclosure to protect the electronics from rain and direct moisture.

Q: What is the power consumption of this module?

A: The module is designed for low power applications. In active measurement mode, it consumes approximately a few hundred microamps, making it suitable for battery-powered projects.

Q: Are there sample code examples available?

A: Yes, you can find numerous open-source libraries and example sketches for Arduino, ESP8266, and ESP32 on GitHub and standard library managers that support both AHT20 and BMP280 chips.

Q: Is this module compatible with Raspberry Pi?

A: Yes, it is fully compatible with Raspberry Pi via the I2C interface. Just ensure you enable I2C in the Raspberry Pi configuration settings and connect the SDA/SCL pins correctly.

Q: Does it come with header pins included?

A: The module typically comes with a set of male header pins in the bag, but they are not pre-soldered to the board to allow for flexible mounting options.
