DHT22 Click Board
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°C to +80°C and relative humidity measurement within 2% accuracy from 0 to 100%. Both relative humidity and temperature data signals have a 16-bit resolution.
DHT22 click includes two jumpers (zero ohm resistors): SDA SEL and PWER SEL. The board has SDA SEL jumper that lets you select either mikroBUS pin CS (SDA1) or mikroBUS pin INT (SDA2) for outputting the one wire signal. The onboard PWER SEL jumper is for switching between either a 3.3V or 5V power supply.
