A0221AU / A02YYUW Waterproof Ultrasonic Distance Sensor

A0221AU / A02YYUW Waterproof Ultrasonic Distance Sensor The ultrasonic sensor features a closed, sealed probe that is waterproof and dustproof, making it suitable for harsh and moist measuring environments. All the signal processing units are integrated within the module, allowing users to obtain the distance value directly through the Asynchronous Serial Interface. With a 9600 bit/s baud rate, the sensor can easily communicate with the upper host or other MCUs, significantly shortening the development cycle for users.
