DESIGN AND CONSTRUCTION OF AN AUTOMATIC CAR IMMOBILIZER

Abstract

This project,car immobilizer is design to protect a car from starting by using an electromechanical switch as a device which prevent an unauthorise operator from starting the car,due to the fact that the time delay,the connectivity and other mechanizm involued in the operation of the imobilization are known only to the car owner. Problem encountered is due to the choice of transistor used, which makes the holding current small,because of the large resistance use has load. The problem is solved using a large load transistor with high collector current gain. The design of this project,car immobilizer is a way of securing vehicles (car) from an intruder because of the difficuity in operation.
