The DHT22 Click Board from Mikroelektronika is one of the simplest temperature and relative humidity sensor click board that carries the AM2302 sensor module, also known as DHT22. Concealed inside a plastic mesh packaging, the AM2302 temperature/humidity sensor needs just a single wire to communicate with the target board microcontroller.

For added convenience, DHT22 click is provided with two jumpers (zero ohm resistors). While one of them allows the user to choose between the MikroBUS pin to use (either CS or INT pin, which are SDA1 and SDA2 lines), the other on-board jumper allows the choice between 3.3V and 5V power supplies. The sensor generates the temperature/humidity data in a 16-bit resolution. The generated decimal number is 10 times the actual measurement, i.e., 216 would be 21.6.

  • Based on the Aosong AM2302 sensor module

  • Low power consumption
  • Two jumpers
  • Outputs data in 16-bit resolution
  • RoHS compliant

Product Details


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 offers temperature measurement within half a degree precision from -40.
