SENS-A02YYUW Ultrasonic Sensor Module A02YYUW, Waterproof, 4.5 meters, 3.3~5V

A02YYUW is a waterproof ultrasonic sensor module with a 4.5 meter effective ranging distance. 

It supports 3.3~5V wide voltage range and is compatible with 3.3V or 5V devices like Arduino, Raspberry Pi, etc. The average current of A02YYUW is only 8mA so it can be powered by most controllers' IO port. The ultrasonic sensor adopts closed separated probe, waterproof and dustproof, which could be well suitable for harsh and moist measuring environment. 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.

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