Aosong DHT (Digital-output Humidity and Temperature Sensor)
The Aosong DHT family of sensors provide temperature and humidity
measurements through a bidirectional serial digital signal. The
DHT11 uses a polymer humidity capacitor with NTC thermistor; the
DHT22 replaces the thermistor with a DS18B20 1-wire thermometer.
The DHT22 is also known as an AM2303.
