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.
