Introduction:
STD002 intelligent vehicle detector is applied in the systems of parking lots, highway toll station and traffic lights controlling. STD002 is mainly used to detect the existing of vehicles and direction detection (counting). When used to detect the existing of vehicles, every loop will provide a group of output signals from an output relay; when used to detect the direction of vehicles, every relay will correspond to an output of direction.
