Good accuracy, easy to integrate

Solid performance on the breadboard. The humidity response is slightly slower than expected in very dry conditions, but overall it meets the specs for general use.

Reliable for plant monitoring

Using these in my smart greenhouse setup. They have been running for three months without drift. The I2C address configuration is straightforward.

Great for university projects

Bought a pack for our engineering lab. Students found the documentation clear and the module robust enough to handle frequent wiring changes.

Perfect drop-in replacement for SHT20

I needed a sensor for my home automation project and this AHT10 worked flawlessly with my existing I2C code. The readings are stable and match my reference meter closely.

Consistent data output

Integrated into a long-term logging system. No communication errors so far, and the precision is exactly what was advertised for this price point.

Low power consumption confirmed

Tested on battery power; the sleep mode works well. Only giving 4 stars because the breakout board pins were a bit tight for my jumper wires.

5 FAQ

Q: Does it require calibration before first use?

A: The AHT10 comes factory calibrated. You do not need to perform manual calibration for standard applications, though a warm-up period of a few seconds is recommended after power-on.

Q: What is the default I2C address?

A: The default 7-bit I2C address for the AHT10 is typically 0x38. Please refer to the datasheet for details on changing this if your specific variant supports it.

Q: Is this module compatible with Arduino Uno?

A: Yes, the AHT10 uses standard I2C communication and operates at 3.3V logic levels, which are compatible with the Arduino Uno when using appropriate pull-up resistors.

Q: What library should I use for ESP32?

A: You can use popular libraries like 'Adafruit AHTX0' or 'SparkFun AHT20/AHT10' available in the Arduino Library Manager, as they support the AHT10 protocol.

Q: Can this sensor be used outdoors directly?

A: The sensor chip itself is not waterproof. For outdoor use, you must house it in a ventilated, weather-proof enclosure to protect it from rain and direct condensation.
