Ultrasonic Distance Waterproof Sensor A02YYUW (DFRobot) - SEN0311
The ultrasonic distance sensor determines the distance to a target by measuring the time lapse between sending and receiving an ultrasonic pulse. This commercial-grade sensor module offers high performance and reliability, featuring a much smaller blind zone, wider sensing angle, and improved penetration through smog and dust compared to similar sensors.
Shipping List
- 1 x A02YYUW Waterproof Ultrasonic Sensor
- 1 x PH2.0-4P Connector
Connection with Arduino:
The sensor uses a closed separate probe design that is waterproof and dustproof, suitable for harsh and moist environments. All signal processing units are integrated inside the module, allowing users to obtain distance values directly via an asynchronous serial interface. With a 9600 bit/s baud rate, the sensor easily communicates with Arduino or other MCUs, significantly reducing development time.
Connection with Raspberry Pi:
Use this sensor with an Arduino controller to build projects such as backing car annunciators, obstacle avoidance robots, or object approach detectors.
