class
adafruit_dht.DHT11(pin, use_pulseio=True)[source]¶ Support for DHT11 device.
Parameters: pin (Pin) – digital pin used for communication
-
class
adafruit_dht.DHT22(pin, use_pulseio=True)[source]¶ Support for DHT22 device.
Parameters: pin (Pin) – digital pin used for communication
-
class
adafruit_dht.DHTBase(dht11, pin, trig_wait, use_pulseio)[source]¶ base support for DHT11 and DHT22 devices
-
humidity¶ humidity current reading. It makes sure a reading is available
Raises RuntimeError exception for checksum failure and for insufficient data returned from the device (try again)
-
measure()[source]¶ measure runs the communications to the DHT11/22 type device. if successful, the class properties temperature and humidity will return the reading returned from the device.
Raises RuntimeError exception for checksum failure and for insufficient data returned from the device (try again)
-
temperature¶ temperature current reading. It makes sure a reading is available
Raises RuntimeError exception for checksum failure and for insufficient data returned from the device (try again)
