DHT Sensor


The dht sensor platform allows you to get the current temperature and humidity from a DHT11, DHT22 or AM2302 device.

Configuration

To use your DHTxx sensor in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  platform: dht
  sensor: DHT22
  pin: 23
  monitored_conditions:
    - temperature
    - humidity

Configuration Variables

sensor

(string)(Required)The sensor type, supported devices are DHT11, DHT22, and AM2302.

pin

(integer)(Required)The pin the sensor is connected to.

name

(string)(Optional)The name of the sensor.

Default value: DHT Sensor

monitored_conditions

(list)(Required)Conditions to monitor. Available conditions are only temperature and humidity.

temperature

Temperature at the sensor’s location.

humidity

Humidity level at the sensor’s location.

temperature_offset

(integer | float)(Optional)Add or subtract a value from the temperature.

Default value: 0

humidity_offset

(integer | float)(Optional)Add or subtract a value from the humidity.

Default value: 0

The name of the pin to which the sensor is connected has different names on different platforms. ‘P8_11’ for Beaglebone, ‘23’ for Raspberry Pi.

Example

An example for a Raspberry Pi 3 with a DHT22 sensor connected to GPIO4 (pin 7):

sensor:
  - platform: dht
    sensor: DHT22
    pin: 4
    temperature_offset: 2.1
    humidity_offset: -3.2
    monitored_conditions:
      - temperature
      - humidity
