DFRobot A02YYUW Waterproof Ultrasonic Sensor

DFRobot A02YYUW Waterproof Ultrasonic Sensor is an easy-to-use commercial-grade sensor module. This DFRobot module determines the distance to a target by measuring the time lapse between sending and receiving the ultrasonic pulse. The A02YYUW sensor features a waterproof and dustproof closed-separated probe suitable for harsh and moist environments. All the signal processing units are integrated inside the module, and the distance value is directly obtained through the Asynchronous Serial Interface. The A02YYUW communicates with the upper-host or other MCU with a 9600bit/s band rate that greatly shortens the developing cycles.
