1. Introduction It is the vehicle loop detector of inductive coil type. The principle is that the vehicle's metal parts can change the inductance value of the detection coil and after analyzed by the microcontroller. It can detect whether the vehicle is present. It is mainly applied to electric door, fast door, barrier gate and occasions that need to detect the vehicle's presence.
