ABSTRACT: Proximity Intruder Security Alarm system, as the name implies, is a system that detects an intruder within a proximity up to two meters range within an unauthorised area. It is a system that alerts security personnel, residents of an environment, and of course scares hoodlums away. This innovative work carried out 4 different tests on 3 types of sensors to ascertain their extent of coverage. The tests were carried out on ultrasonic sensor, infrared sensor, and linear sensor. The test analyses shows that ultrasonic sensor has a longer distance up to 1.8 meters and wider radius coverage of 360o, linear sensor 1.5 meters, 90o, and infra-red sensor 1 meter, 90o. The following components were used to achieve this laudable innovative work: linear, infra-red or ultrasonic sensor any of the sensors can be used along with contactor, revolving light, control box, auxiliary contacts, alarm, reset switch, pilot lamps, sling, hard object, motor, limit switch and power cord. It was concluded that criminality and insecurity had continued to subject private homes, business offices and industrial areas into state of dilemma, dwindling social and economic development of the nation. The following recommendations were proffered, that the system should be installed in places like residential, commercial areas, industrial, mini stores, super market, banks, all dwellings areas for protection against burglary, (theft) or property damage, as well as personal protection against intruders.
