DHT Temperature+Humidity Sensor
|
|
===============================
|
|
|
|
The DHT Temperature+Humidity sensor allows you to use your DHT11
|
|
(`datasheet <https://akizukidenshi.com/download/ds/aosong/DHT11.pdf>`__,
|
|
`adafruit <https://www.adafruit.com/product/386>`__), DHT22
|
|
(`datasheet <https://www.sparkfun.com/datasheets/Sensors/Temperature/DHT22.pdf>`__,
|
|
`adafruit <https://www.adafruit.com/product/385>`__), AM2302
|
|
(`datasheet <https://cdn-shop.adafruit.com/datasheets/Digital+humidity+and+temperature+sensor+AM2302.pdf>`__,
|
|
`adafruit <https://www.adafruit.com/product/393>`__) and RHT03
|
|
(`datashet <https://cdn.sparkfun.com/datasheets/Sensors/Weather/RHT03.pdf>`__,
|
|
`sparkfun <https://cdn.sparkfun.com/datasheets/Sensors/Weather/RHT03.pdf>`__)
|

# Example configuration entry
|
|
sensor:
|
|
- platform: dht
|
|
pin: D2
|
|
temperature:
|
|
name: "Living Room Temperature"
|
|
humidity:
|
|
name: "Living Room Humidity"
|
|
update_interval: 15s
|
|
|
|
Configuration variables:
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- **pin** (**Required**, `pin </esphomeyaml/configuration-types.html#pin>`__): The pin where the DHT bus is connected.
|
|
- **temperature** (**Required**): The information for the temperature
|
|
sensor
|
|
|
|
- **name** (**Required**, string): The name for the temperature
|
|
sensor.
|
|
- All other options from
|
|
`Sensor </esphomeyaml/components/sensor/index.html#base-sensor-configuration>`__
|
|
and `MQTT
|
|
Component </esphomeyaml/components/mqtt.html#mqtt-component-base-configuration>`__.
|
|
|
|
- **humidity** (**Required**): The information for the humidity sensor
|
|
|
|
- **name** (**Required**, string): The name for the humidity sensor.
|
|
- All other options from
|
|
`Sensor </esphomeyaml/components/sensor/index.html#base-sensor-configuration>`__
|
|
and `MQTT
|
|
Component </esphomeyaml/components/mqtt.html#mqtt-component-base-configuration>`__.
|
|
|
|
- **model** (*Optional*, int): Manually specify the DHT model, can be
|
|
one of ``AUTO_DETECT``, ``DHT11``, ``DHT22``, ``AM2303``, ``RHT03``
|
|
and helps with some connection issues. Defaults to ``AUTO_DETECT``.
|
|
- **update_interval** (*Optional*, `time </esphomeyaml/configuration-types.html#time>`__): The interval to check the
|
|
sensor. Defaults to ``15s``.
|
|
- **id** (*Optional*, `id </esphomeyaml/configuration-types.html#id>`__): Manually specify the ID used for code
|
|
generation.
|
|
|
|
.. note::
|
|
|
|
If you're seeing lots of invalid temperature/humidity warnings in the logs, try manually setting the
|
|
DHT model with the ``model:`` configuration variable. Other problems could be wrong pull-up resistor values
|
|
on the DATA pin or too long cables.
