Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This A01NYUB Waterproof Ultrasonic Sensor features a farther monitoring distance, wider detection range and a certain penetration power(smog, dust). The product comes with a removable bell mouth and the effective measuring distance is 7.5m when the bell mouth is installed.

The ultrasonic sensor features a waterproof and dustproof transmitter and receiver. It utilizes a closed probe design and comes integrated with all signal processing units. Users can easily obtain the distance value via the Asynchronous Serial Interface. The sensor operates at a 9600bit/s band rate and can communicate with upper-host or other MCU, significantly shortening the development 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.
