    :image: sht3xd.jpg

The ``sht3xd`` sensor platform Temperature+Humidity sensor allows you to use your Sensirion SHT31-D/SHT3x
(`datasheet <https://cdn-shop.adafruit.com/product-files/2857/Sensirion_Humidity_SHT3x_Datasheet_digital-767294.pdf>`__,
`Adafruit`_ ) sensors with
ESPHome. The :ref:`I²C Bus <i2c>` is
required to be set up in your configuration for this sensor to work.

    # Example configuration entry
    sensor:
      - platform: sht3xd
        temperature:
          name: "Living Room Temperature"
        humidity:
          name: "Living Room Humidity"
        address: 0x44
        update_interval: 60s

Configuration variables:
------------------------

- **temperature** (**Required**): The information for the temperature sensor.

  - **name** (**Required**, string): The name for the temperature sensor.
  - **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
  - All other options from :ref:`Sensor <config-sensor>`.

- **humidity** (**Required**): The information for the humidity sensor.

  - **name** (**Required**, string): The name for the humidity sensor.
  - **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
  - All other options from :ref:`Sensor <config-sensor>`.

- **address** (*Optional*, int): Manually specify the I²C address of the sensor.
  Defaults to ``0x44``.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
  sensor. Defaults to ``60s``.
- **heater_enabled** (*Optional*, bool): Turn on/off heater at boot.
  This may help provide `more accurate readings in condensing conditions <https://forum.arduino.cc/t/atmospheric-sensors-in-condensing-conditions/412167>`_,
  but can also increase temperature readings and decrease humidity readings as a side effect.
  Defaults to ``false``.
