Parking Gate Single Loop Detector Car Detection Sensor With 10 Sensitivity Grade
Introduction
IVD-500 is used for vehicles detecting for example for monitoring and safe-guarding access ways or for counting vehicles. The output signal can be used for controlling door drive mechanisms, operating barriers, activating card dispensers etc.

Principle
It is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor.
