Ultrasonic range finder – 20012
The Ultrasonic Rangefinder is the sensor that can give your robot a picture of its surroundings. This sensor measures distance by sending out ultrasonic waves, allowing you to determine the exact distance of an obstacle in the sonar field of view.

Waves that bounce off an obstacle find their way back to the sensor. It adopts an industrial-level AVR MCU as a processor. Temperature correction and compensation modules are included. Its RS485 interface allows sensors of this kind to be connected to a network.
