The dht sensor platform allows you to get the current temperature and humidity from a DHT11, DHT22 or AM2302 device.
{% linkable_title 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 %} sensor: description: The sensor type, supported devices are DHT11, DHT22, and AM2302. required: true type: string pin: description: The pin the sensor is connected to. required: true type: integer name: description: The name of the sensor. required: false default: DHT Sensor type: string monitored_conditions: description: Conditions to monitor. Available conditions are only temperature and humidity. required: true type: list keys: temperature: description: Temperature at the sensor's location. humidity: description: Humidity level at the sensor's location. temperature_offset: description: Add or subtract a value from the temperature. required: false default: 0 type: [integer, float] humidity_offset: description: Add or subtract a value from the humidity. required: false default: 0 type: [integer, float] {% endconfiguration %}
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.
{% linkable_title 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
