Description
The AM2320 is a basic temperature and humidity sensor for I2C compatible microcontrollers and single board computers. These are similar in size / construction as the DHT11 and DHT22, however these do not require a bit-bang timing specific protocol and work with regular I2C. The AM2320 can monitor temperatures between -40°C and 80°C and Humidity between 0 and 99.9%
To use this sensor: just connect the sensor up to a microcontroller or single board computer with I2C and the sensor will be readable at address 0x5c. The sensor pinout is 1:VDD 2:SDA 3:GND 4:SCL with pullup resistors (generally between 3K and 10K Ohm) required on SDA and SCL. These resistors are sold separately.
