DHT22 Click Board™

The DHT22 Click Board™ 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 half a degree of 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.

IC/module: AM2302 temperature-humidity sensor

AM2302 is a basic, low-cost digital temperature and humidity sensor in a large plastic body. It is fairly simple to use and yield accurate data once every 2 seconds. Assuring reliability and stability, it uses a capacitive humidity sensor and a thermistor to measure the surrounding air and provides a digital signal on the data pin.

Temperature and Humidity Measurement Range

The sensor of the DHT22 Click Board™ offers temperature measurement within half a degree precision from -40.
