This sensor allows you to use A02YYUW waterproof ultrasonic sensor by DFRobot
|
||
|
|
(`datasheet <https://wiki.dfrobot.com/_A02YYUW_Waterproof_Ultrasonic_Sensor_SKU_SEN0311>`__)
|
||
|
|
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, :ref:`sensor-filters` are highly recommended.
|
||
|
|
|
||
|
|
To use the sensor, first set up an :ref:`uart` with a baud rate of 9600 and connect the sensor to the specified pin.
