DHT22 click is a temperature and humidity measurement board carrying the sensor of the same name. It’s a low cost reliable solution that communicates with the target board microcontroller through a single Serial Data Line. The sensor can detect temperatures between –40 and 80 degrees centigrade with a half a degree precision. The relative humidity measurement from 0–100% is accurate within 2%. DHT22 has two jumpers. One for choosing between two mikroBUS pins (CS or INT) for communicating with the target board microcontroller. Another for setting up the power supply voltage either at 3.3V or 5V.
