How to used JUTAI inductive vehicle loop detector for auto gate?

JUTAI loop detector , inductive loop ,vehicle loop detector, vehicle loop sensor inductive loop detector LD-100/LD-102/ LD-200/LD-202/LD-105/LD-106 An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire . Vehicle detection loops, called inductive-loop traffic detectors, can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement. Vehicle Loop Detectors. An inductive loop detector is used to detect motor vehicles. When the motor vehicle drives over the detectors wire loop the detectors senses the metal and then a relay is activated. This relay is connected to the motor controller card to automatically open the gate or door. Vehicle Loop de...
