A02YYUW Waterproof Ultrasonic Sensor

This sensor allows you to use A02YYUW waterproof ultrasonic sensor by DFRobot (datasheet) with ESPHome to measure distances. This sensor can measure ranges between 3 centimeters and 450 centimeters with a resolution of 1 millimeter.

Since this sensor reads multiple times per second, Sensor Filters are highly recommended.

To use the sensor, first set up an UART Bus with a baud rate of 9600 and connect the sensor to the specified pin.

# Example configuration entry
sensor:
  - platform: "a02yyuw"
    name: "Distance"

Configuration variables

• uart_id (Optional, ID): The ID of the UART bus you wish to use for this sensor. Use this if you want to use multiple UART buses at once.

• All other options from Sensor.

NOTE

PWM and RS485 versions of the A02YYUW are not supported by this component.
