A02YYUW Waterproof Ultrasonic Sensor (SEN0311)

INTRODUCTION

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 a 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 a closed separate 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 a 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 annunciator, obstacle avoidance robot, object approaching detection, etc.
