Adafruit AHT20 - Temperature & Humidity Sensor Breakout Board -...
The AHT20 is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the DHT22. You can take sensor readings as often as you like, and it uses standard I2C so its super easy to use with any Arduino or Linux/Raspberry Pi board.
This sensor has a typical accuracy of +- 2% relative humidity, and +-0.3 °C at 20-80% RH and 20-60 °C. There is only one I2C address so it's not a good option when you need multiple humidity sensors.
As with all Adafruit breakouts, we've done the work to make this handy temperature-and-humidity super easy to use. We've put it on a breakout board with the required support circuitry and connectors to make it easy to work with and is now a trend we've added SparkFun Qwiic compatible STEMMA QT JST SH connectors that allow you to get going without needing to solder. Just use a STEMMA QT adapter cable, plug it into your favorite microcontroller or Blinka supported SBC and you're ready to rock! QT Cable is not included, but we have a variety in the shop.

Technical Details
Specifications:
- Use with 3.3V or 5V power/logic
- I2C address 0x38
- Operational Temperature range: -40 to 85 °C (+-1 °C typical accuracy over entire range)

Revision History:
- As of Dec 10th, 2024 - We're using the version of the sensor with a PTFE filter.
- As of July 3, 2024 - We've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen. You may get the new PCB or the older version with vector fonts; both are identical other than the fancy silkscreen.
- As of September 16, 2022 - this sensor breakout may come with black or tan STEMMA QT connectors - they work the same!
