.. note::

    When configured for humidity, the log *'Components should block for at most 20-30ms in loop().'* will be generated in verbose mode. This is due to technical specs of the sensor and can not be avoided.

    # Example configuration entry
    sensor:
      - platform: aht10
        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 <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>`.

- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
