Good module, pins need header
Great sensor but comes without headers. You need to solder them yourself which is fine for me.

Great value for money
Bought five for a class project. All of them worked out of the box without issues.

Easy library support
Found libraries easily for Arduino IDE. Setup took less than 10 minutes from unboxing to data.

High precision as advertised
Compared it against a calibrated unit in the lab. The variance is minimal and well within specs.

Perfect for my weather station
Works flawlessly with my ESP32 project. Readings are consistent and the I2C connection is stable.
Q: Is calibration needed?
A: Sensors are factory calibrated. However, software offset can be applied if needed for specific environments.
Q: Is this 5V tolerant?
A: Yes, the module includes a voltage regulator allowing safe operation between 3.3V and 5V.
Q: Can I use this outdoors?
A: The module itself is not waterproof. Please house it in a weatherproof enclosure with ventilation.
Q: Does it come with headers?
A: No, soldering is required. This allows flexibility for direct wiring or header usage.
Q: What are the I2C addresses?
A: The AHT20 default address is 0x38 and the BMP280 default address is 0x76.
