Vehicle Loop Detector Circuit Schematic

This circuit can also be used in conjunction with my delay.

Vehicle loop detector circuit schematic.

Into the designated loop. This tiny test coil was for testing only on my work bench and although it works detection distance is not very good. The loop resonates at a constant frequency that the detector monitors. Set the sensitivity to the lowest setting that will detect a bicycle.

If the inductive loop is placed correctly it will detect vehicle open gate and keep it open until the vehicle clears the gate. Detection distance is much better with a large 6 foot coil. Loop detector schematic modified to drive a relay. A circuit used to detect a vehicle on blacktop pavement concrete and trigger an alarm or relay.

Observe the detection call light on the detector module for all sensitivity settings. Extension cable which in turn connects to the vehicle detector. The detector powers the loop causing a magnetic field in the loop area. The number of turns in the loop is determined by the size of the loop.

Executive summary of the induction loop vehicle detector. For high bed vehicle detection the typical loop size is 6 x 8. The time will be calculated by arduino when the vehicle interrupts the start laser the timer begins and when the vehicle interrupts the end laser the timer stops and applying the values to the equation arduino will find the speed of the vehicle. The octal connector is available as a harness or a mountable socket.

An induction loop vehicle detector comprises an oscillator circuit having a plurality of capacitors switchable in circuit with a road loop under the control of a microcomputer to determine the oscillator frequency. View more loop detector loop overview. The microcomputer monitors the oscillator frequency and controls the switching of the capacitors to periodically return the frequency to a predetermined value.

Loop detectors are available as direct plug in for specific gate operator control boards or use a universal 11 pin octal connector. Drive a large vehicle over adjacent lanes loop detectors and observe if a false call spillover is detected.
