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 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 installed.

Connection with Arduino

The ultrasonic sensor adopts closed probe of transmitter & receiver, waterproof and dustproof. 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.

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.
