Abstract
A system is provided for sensing the presence of a standard component of a locking mechanism of a door of a trailer when the door is moved to the closed position and is secured. A sensor is provided on the trailer proximate to the locking mechanism. The sensor automatically reacts when a ferrous target comes within its sensing range. Control circuitry on the trailer processes and uses signals from the sensor to perform various functions.
