Description
When the DHT11 isn't precise enough, the DHT22 (also sold as AM2302) is the drop-in upgrade. Same wiring, same libraries, but a much wider range and better accuracy – good for greenhouses, incubators, data loggers and outdoor weather stations.
Features
- Humidity 0–100 % RH, ±2 % RH (typical)
- Temperature −40 to 80 °C, ±0.5 °C
- 0.1 resolution for both readings
- 3.3–6 V supply, single-wire digital output
- Module version with pull-up resistor: VCC, DATA, GND
Good to know
Read it no faster than once every 2 seconds. In the Arduino DHT library, select type DHT22.
