The Zio Ultrasonic Distance Sensor is an ultrasonic distance sensor based on the HC-SR04 sensor. Unlike the :doc:`Ultrasonic Distance Sensor component </components/sensor/ultrasonic>`, measurements are read over the I²C bus.

To use the sensor, first set up an :ref:`I²C Bus <i2c>` and connect the sensor to the specified pins.

    # Example configuration entry
    sensor:
      - platform: zio_ultrasonic
        name: "Distance"
        update_interval: 60s

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

- **address** (*Optional*, int): Manually specifiy the I²C address of the sensor. Defaults to ``0x00``.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
- All other options from :ref:`Sensor <config-sensor>`.
