A02YYUW Waterproof Ultrasonic Distance Sensor (3~450cm, UART, IP67)

Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This is an easy-to-use commercial-grade ultrasonic sensor module of high performance and reliability, featuring much smaller blind zone, wider sensing angle and a certain penetration power (smog, dust) compared with other similar sensors.

Connection with Arduino

The ultrasonic sensor adopts closed separated probe, waterproof and dustproof, which could be well suitable for harsh and moist measuring environments. All the signal processing units are integrated inside the module , so users can directly obtain the distance value through Asynchronous Serial Interface. With 9600bit/s band rate, the sensor can easily communicate with upper-host or other MCU, which greatly shortens the developing cycle for users.

Connection with Raspberry Pi

Use the sensor with Arduino controller to build up your projects, such as backing car announcer, obstacle avoidance robot, object approaching detection etc.
