Reliable sensor for smart home
Integrated this into my ESP32 setup. No drift observed over two weeks of continuous operation. The digital signal output is clean and noise-free.

High precision as advertised
I tested all three models (AHT10/20/30). The AHT30 offers the best stability for long-term logging. Fast response time when humidity changes suddenly.

Accurate soil ambient monitoring
Placed it inside a protective casing to monitor ambient conditions near my plants. It handles the slight condensation well without failing. Very satisfied.

Perfect for my weather station project
The I2C communication was easy to set up with my Arduino. The readings are stable and match my reference meter closely. Highly recommended for DIY enthusiasts.

Good value, small footprint
Works well for monitoring humidity in my greenhouse. The module is very compact. Only giving 4 stars because the pin headers were not included, had to solder my own.
Q: Does this come with a library for Arduino?
A: While we do not host the library directly, this sensor is supported by popular open-source libraries available in the Arduino Library Manager. Search for 'AHTxx' to find compatible code.
Q: What is the difference between AHT10, AHT20, and AHT30?
A: The main differences lie in accuracy and response time. AHT30 generally offers higher precision and faster response compared to AHT10 and AHT20, suitable for more demanding applications.
Q: Is this module compatible with Raspberry Pi?
A: Yes, the module operates on I2C protocol and supports voltages from 2.2V to 5.5V, making it fully compatible with Raspberry Pi GPIO pins.
Q: What is the power consumption in sleep mode?
A: The sensor features a low-power mode. In sleep state, current consumption drops to microamps, making it ideal for battery-powered applications.
Q: Can I use this outdoors directly?
A: The sensor module itself is not waterproof. For outdoor use, you must house it in a breathable, weatherproof enclosure to protect the electronics from rain and direct water exposure.
