This little sensor looks an awful lot like the popular DHT11/DHT22 temperature and humidity sensors, but unlike classic DHT sensors, it has an I2C interface! That's right, you do not need to use a bit-bang timing-specific protocol to talk to the AM2320, it uses plain-old-I2C. Whew, that makes things a little easier, doesn't it?

But! We'll let you know, this sensor is not well documented like Adafruit's other, fancier I2C temperature & humidity sensors. The datasheet mentions it has 3% humidity accuracy and 0.5C temperature accuracy, but Adafruit are not very trusting of the specifications. So, while this sensor does seem to work, it's not recommended for anything where you care deeply about guaranteed accuracy. Temperature is probably correct to 2-3 degrees Celsius. Humidity is probably within 5-10%.

That said, for maker and IoT projects? You can't beat the simplicity and price! And Adafruit have got ready-to-go working Arduino and CircuitPython code to use it. Check out Adafruit's detailed guide for wiring diagrams, code, datasheet and more

Each order comes with one AM2320, a low-cost temperature and humidity sensor. You just provide any microcontroller that can run Adafruit's Arduino or CircuitPython library, and two I2C pull-up resistors (not included).

Technical Details

  • Standard I2C and 1-Wire bus output (note Adafruit have not tried 1-Wire)
  • Signal transmission distance up to 20 meters
  • I2C interface (address 0x5c)
  • 3.3V / 5V tolerant
  • 0.1 C / % RH (relative humidity) resolution (+/- 0.5 C, 3% RH)
