The principle is similar to that of bat's acoustic wave ranging. Using the command and control of the microcomputer system operation, the sound and the display respectively indicate the orientation of the obstacle and the distance between the vehicle body and the obstacle, thereby achieving collision prevention against unburned. The features of this collision avoidance system: 1. Front anti-friction angle, anti-collision behind the car 2. Eight-direction detection 3. Microcomputer intelligent control, accurate digital display obstacle distance 4. Not affected by the environment 5. Anti-electromagnetic interference, no impact on the original electronic system. 6. The probe is embedded in installation, multi-color configuration. The sensor is exquisite and compact, and easy to install. Car reversing radar technical parameters: 1.
