More info


Waterproof ultrasonic distance sensor module with a range of up to 4.5 m. Can be powered with a voltage range of 3.3 to 5 V and is compatible with 3.3 V or 5 V devices such as ArduinoRaspberry Pi etc. The average current A02YYUW is only 8 mA, so it can be powered via the IO port of most controllers.

The ultrasonic sensor is enclosed in a waterproof and dustproof housing, which means that it will be used in difficult and humid measuring conditions. All signal processing units are integrated in the module, communication with the module takes place via the UART interface.

An example of a sensor service code is available on the manufacturer's website.
