A02YYUW Waterproof Ultrasonic Distance Sensor

Most ultrasonic distance sensors are not waterproof, which can be a problem if you want to use the sensor outdoors or in damp environments, for example in a water tank to measure the water level. DFRobot has a reliable ultrasonic distance sensor with a waterproof emitter for this application area. This sensor is suitable for outdoor applications such as reversing sensors, security alarms, industrial inspections, level monitoring, water level monitoring in water tanks, etc. This waterproof ultrasonic sensor A02YYUW gives you a large monitoring distance of 3cm to 450cm. The sensor has a sealed transmitter and receiver that is water and dustproof. The signal processing unit is integrated into the sensor module, so you can read the distance value directly via the asynchronous serial interface. With a baud rate of 9600Bit/s, the sensor can communicate with the microcontroller, significantly reducing development time for the user.
