 Datasheets | | |  Honeywell's Magnetic Sensors offer a Low-Cost Solution for Vehicle Recognition and Vehicle Detection Systems
Whether mounted in the pavement, or alongside vehicle traffic lanes, Honeywell's magneto-resistive sensor technology offers high sensitivity solutions for detecting vehicles. From bicycles to fork lifts to automobiles to locomotives to airplanes, these vehicles contain ferrous materials that disturb the uniform intensity and direction of the earth's magnetic field. Depending on ferrous material content and proximity to the sensors, vehicle disturbances of the earth's magnetic field from 15 meters or more can be detected. Automobiles can easily be detected within one meter of the sensor without significant discrimination circuitry. Typical applications include door opening, safety crossbar operation, traffic monitoring, parking space detection, and vehicle location/positioning.
Combinations of sensors can be used with enhanced signal processing to do vehicle recognition/signature collection task. Additionally small displacements of identically oriented sensors can be used to determine vehicle direction and speed information. Because Honeywell's magnetic sensors are very small and environmentally robust, they make cost-effective implementations and retrofits for detecting vehicles and traffic. |
