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 milimeter.

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.
