HTU21D | Si7021 | SHT21 Temperature & Humidity Sensor ===================================================== .. seo:: :description: Instructions for setting up HTU21D temperature and humidity sensors. :image: htu21d.jpg :keywords: HTU21D The HTU21D Temperature & Humidity component allows you to use HTU21D, Si7021 and SHT21 sensors with ESPHome. The :ref:`I²C Bus ` is required to be set up in your configuration for this sensor to work. Example sensors: - (`Adafruit `__) .. 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% .. code-block:: yaml # Example configuration entry sensor: - platform: htu21d model: htu21d temperature: name: "Temperature" humidity: name: "Humidity" heater: name: "Heater" Configuration variables: ------------------------ - **temperature** (*Optional*): The information for the temperature sensor. All options from :ref:`Sensor `. - **humidity** (*Optional*): The information for the humidity sensor. All options from :ref:`Sensor `. - **heater** (*Optional*): The information for the heater sensor. All options from :ref:`Sensor `. - **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``. - **model** (*Optional*): Possible values are HTU21D, SI7021, SHT21. Defaults to HTU21D. The heater may be enabled to help correct the reading; see the datasheet for more information.
