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 Board™ is provided with two jumpers (zero Ω 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

  • Temperature range:
  • Humidity range: 0 to 100%
  • Calibrated digital signal
  • 3.3V or 5V power supply
  • Selectable communication pin
  • 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.
