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.
# 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.
