Essential Considerations for Installing Ground Loop Sensors in Parking Systems
Principle of Vehicle Detectors and Ground Loops in Parking Lots
1. Working Principle
Ground loop vehicle detectors are based on the principle of electromagnetic induction. They are typically embedded under the roadbed of the same lane in a circular loop, powered by a working current, acting as a sensor. When a vehicle passes over or stops on this loop, the iron content of the vehicle alters the magnetic flux within the
