- 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 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 9600 bit/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.
