ABSTRACT
This project work has covered the design of an automatic security lighting system for ATBU, Yelwa Campus. Requirements for illuminance, type of fittings, power dissipation and mounting height were put into consideration. An electronic model of the campus was built with the streets outlined and lamps fixed at positions along the streets according to the design. An electronic control, based on a Light Dependent Resistor (LDR) is built, which provides automatic switch on and switch off of the system at dusk and dawn respectively. A delay is incorporated so that the circuit does not responds to small changes in illumination and any momentary brightness the transducers may sense and power requirements for the system is evaluated.
