HTU21D Temperature+Humidity Sensor ================================== .. seo:: :description: Instructions for setting up HTU21D temperature and humidity sensors. :image: htu21d.jpg :keywords: HTU21D The HTU21D Temperature+Humidity sensor allows you to use your HTU21D (`datasheet `__, `adafruit `__) sensors with ESPHome. The :ref:`I²C Bus ` is required to be set up in your configuration for this sensor to work. .. figure:: images/htu21d-full.jpg :align: center :width: 50.0% HTU21D Temperature & Humidity Sensor. .. _Adafruit: https://learn.adafruit.com/adafruit-htu21d-f-temperature-humidity-sensor/overview .. figure:: images/temperature-humidity.png :align: center :width: 80.0% .. note:: The **SI7021** sensor also works with this integration. .. code-block:: yaml # Example configuration entry sensor: - platform: htu21d temperature: name: "Living Room Temperature" humidity: name: "Living Room Humidity" 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 ` and :ref:`MQTT Component `. - **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 ` and :ref:`MQTT Component `. - **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
