The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use, but requires careful timing to grab data.
- Pre-calibrated digital signal output
- Wide temperature measurement range: -40°C to +80°C
- 0 to 100% relative humidity range with 2-5% accuracy
- Long-distance signal transmission up to 20 meters
- Includes pull-up resistor on PCB break-out board
- Standard 3-pin interface (VCC, GND, DATA)
