DHT22 Temperature Humidity Sensor
—The DHT22 is a digital temperature and humidity sensor that returns calibrated readings over a single data wire — the higher-accuracy successor to the DHT11.
Specifications
- Temperature range -40 to 80 °C, typical accuracy ±0.5 °C
- Humidity range 0–100% RH, typical accuracy ±2–5%
- Single-wire digital interface — one GPIO pin
- Supply 3.3–6 V DC
- Sampling interval about 2 seconds
What you can build with the DHT22 Temperature Humidity Sensor
- Room and greenhouse climate monitoring
- Home-automation temperature logging
- Weather stations
- Server-cupboard and grow-tent monitoring
Compatibility
Arduino, Raspberry Pi, ESP8266/ESP32 — supported by the common DHT libraries.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
