The DHT22 (AM2302) is a more accurate and wider-range upgrade to the DHT11. Uses a capacitive humidity sensor and thermistor with a calibrated single-wire digital output. More precise and works across a broader temperature and humidity range. Note: readings update once every 2 seconds. Requires a 4.7k–10kΩ pull-up resistor from DATA to VCC.
