Specification

Description

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 our other, fancier I2C temperature & humidity sensors. The datasheet mentions it has 3% humidity accuracy and 0.5C temperature accuracy, but we're 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%.

Technical Details

  • Standard I2C and 1-Wire bus output (note we 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)

Physical Attributes

  • L x W x H (mm): 22.5 x 12.0 x 4.7
  • Weight (gm) : 1.1
