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.
