Loopsensors

Loopsensors, also known as inductive loop detectors or vehicle detection loops, are a common technology used for detecting the presence of vehicles. They are typically installed in roadways, parking lots, and other areas where vehicle traffic needs to be monitored. The basic principle of operation involves an electrical loop of wire embedded in or placed on the surface of the road. When current flows through this loop, it creates a magnetic field. As a vehicle, which is a metallic object, passes over the loop, it disturbs this magnetic field. This disturbance is detected by the sensor circuitry, which then signals the presence of a vehicle.

The detection can trigger various actions. In traffic management, loopsensors can be used to adjust traffic signal timings, optimize traffic flow, and provide data for traffic analysis. In parking systems, they can indicate whether a parking space is occupied or vacant. They are also employed in toll collection systems to count vehicles and in security systems to detect unauthorized vehicle entry. The size and shape of the loop can be optimized for different applications, such as detecting specific types of vehicles or ensuring accurate detection within a defined area. Loopsensors are generally robust and have a long lifespan, making them a reliable and cost-effective solution for vehicle detection.
