How To Make A Vehicle Ground Loop Detection Sensor Circuit

Learn how to make a vehicle ground loop detection sensor circuit to detect a vehicle on blacktop, pavement, concrete and trigger an alarm or relay. This ground loop detection circuit can also be used in conjunction with my "Delayed Power Off" circuit video to allow the circuit to remain on for a set time after the coil has been triggered by a vehicle. You can also add an inexpensive Ebay electronic counter to this circuit to be able to count vehicles that pass over the coil.
