Much better than the old DHT11
The precision on this AHT20 is noticeably better than my old DHT11 modules. The I2C interface makes wiring much cleaner with fewer pins needed. Highly recommended for any serious weather station project.

Standard for new projects
We have switched all our workshop environmental monitors from DHT11 to AHT20. The improved accuracy and faster response time make a real difference in our data logging experiments.

Good value for money
Bought a pack of five for a university project. All of them worked out of the box. The accuracy is sufficient for our needs, though calibration might be needed for industrial applications.

Easy library support
Found a library for this sensor immediately on GitHub. Had it up and running with an ESP32 in under 10 minutes. The data readings are consistent and match my calibrated reference meter closely.

Great for greenhouse monitoring
Using these to monitor humidity in my indoor greenhouse. They seem very stable and respond quickly to changes when I mist the plants. Only giving 4 stars because the documentation could be slightly clearer for beginners.

Compact and reliable
The form factor is tiny, which is perfect for fitting into custom 3D printed enclosures. No drift observed over two weeks of continuous operation. Excellent upgrade for home automation sensors.
Q: Does this come with headers soldered?
A: This specific listing is for the bare module. Headers are not pre-soldered, giving you the flexibility to solder your own pins or connect via wires depending on your project requirements.
Q: Can this sensor be used outdoors directly?
A: The sensor module itself is not waterproof. For outdoor use, you must house it in a breathable enclosure that protects against rain and direct sunlight while allowing air flow for accurate readings.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, but please note the operating voltage is 1.8V to 3.6V. You should use a logic level shifter or a breakout board with a voltage regulator when connecting to 5V systems to avoid damaging the sensor.
Q: What is the default I2C address?
A: The default I2C address for the AHT20 sensor is typically 0x38. This can usually be confirmed by running an I2C scanner sketch on your microcontroller.
Q: How often should I poll the sensor for data?
A: The sensor has a measurement conversion time of roughly 80ms. However, for most applications, polling every 1 to 2 seconds is sufficient to capture environmental changes without overloading the bus.
