Easy to integrate
Library support is excellent. I had it up and running in under 10 minutes. The form factor is compact and fits easily into small enclosures.

Perfect for my ESP32 project
The I2C communication was seamless with my ESP32 board. The readings are stable and match my reference meter closely. Great value for the price.

Reliable but needs calibration
Works well for monitoring my indoor plants. I noticed a slight offset in humidity initially, but after running it for 24 hours, it stabilized nicely.

High precision as advertised
I am using these in a professional data logging setup. The consistency between multiple units is impressive. Highly recommended for serious projects.

Good sensor, fragile pins
The sensor itself works great, but the header pins bent slightly during shipping. Had to straighten them carefully before soldering. Functionality is fine though.

Best budget humidity sensor
Switched from DHT11 to this AHT20 module and the difference in accuracy and response time is night and day. Will definitely buy more.
Q: Can this be used outdoors directly?
A: The sensor module itself is not waterproof. For outdoor use, you must house it in a weatherproof enclosure that allows air circulation while protecting it from rain and direct sunlight.
Q: Is this compatible with Raspberry Pi?
A: Yes, this module uses the I2C protocol which is fully supported by Raspberry Pi. You just need to enable the I2C interface in the raspi-config settings.
Q: Does it come with a library for Arduino?
A: While we do not provide a proprietary library, this sensor is widely supported by popular open-source libraries available in the Arduino Library Manager, such as 'AHTxx'.
Q: What is the power consumption?
A: The power consumption is very low, typically around 0.5mA during measurement and less than 10µA in sleep mode, making it ideal for battery-powered applications.
Q: What is the difference between AHT10, AHT20, and AHT30?
A: The main differences lie in accuracy and response time. The AHT30 offers the highest precision and fastest response, while the AHT10 is the most cost-effective option for general use.
