SHT3X-D Temperature+Humidity Sensor
===================================

:description: Instructions for setting up SHT31-D/SHT3x and SHT85 temperature and humidity sensors
: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`_ ) and SHT85 (`datasheet <https://sensirion.com/media/documents/4B40CEF3/640B2346/Sensirion_Humidity_Sensors_SHT85_Datasheet.pdf>`__,
`Sensirion`_ ) 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** (*Optional*): 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** (*Optional*): 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``. For SHT3x, an alternate address can be ``0x45`` while SHT85 supports only address ``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``.
