Good performance, slow startup

The sensor is accurate once it warms up, but it takes a few seconds to initialize compared to some newer models. Still, for the cost, it's a solid choice for static monitoring.

Great value for hobby projects

Using these in my home greenhouse monitoring system. The humidity readings match my calibrated hygrometer very closely. Only giving 4 stars because the documentation could be more detailed.

Bulk order success

Bought 50 units for our university lab. Every single module passed our initial sanity checks. Students find them easy to wire up for their sensor networks.

Reliable I2C communication

Integrated easily into our ESP32 project. The I2C bus remains stable even with long wires. Temperature accuracy is impressive for the price point.

Exceeded expectations

Very low power consumption in sleep mode. Perfect for my battery-powered weather station. The data sheet provided all the register maps I needed.

Perfect drop-in replacement

I needed a substitute for the SHT20 which was out of stock. The AHT10 worked flawlessly with my existing Arduino code after minor address adjustments. Readings are stable and consistent.

5 FAQ

Q: Does it come with pull-up resistors installed?

A: Most breakout boards include pull-up resistors, but if you are buying the raw DFN component, you must add external pull-up resistors (typically 4.7kΩ) to the SDA and SCL lines.

Q: Can I use this outdoors directly?

A: No, this is a bare module/sensor chip. It is not waterproof or UV resistant. You must house it in a proper enclosure with a breathable membrane if used outdoors.

Q: What is the default I2C address?

A: The default 7-bit I2C address for the AHT10 is 0x38. This cannot be changed via software as there are no address selection pins on this package.

Q: How do I calibrate the sensor?

A: The AHT10 comes factory calibrated. Re-calibration is generally not required for standard applications. For high-precision needs, compare against a reference instrument and apply software offsets in your code.

Q: Is this module compatible with 5V logic levels?

A: The sensor operates between 1.8V and 3.6V. If you are using a 5V microcontroller like an Arduino Uno, you must use a logic level converter or voltage divider on the SDA and SCL lines to prevent damage.
