Description
This ultrasonic distance measuring module is A02yyuw sensor. It includes transmitter and receiver. The range detector uses waterproof design. And protection class is IP67. Moreover, it has small detection blind spot. That is only 3cm. This sensor has measurement distance 450cm.
In addition, the A02yyuw ultrasonic sensor has many applications. We can use it for robot proximity obstacle avoidance. At the same time, it can help the robot avoid falling. It can also be used for waste overfill detection. Of course, you can use A02yyuw module with arduino.
