DESIGN AND CONSTRUCTION OF SECURITY LIGHTING CONTROL SYSTEM USING MOBILE PHONE

ABSTRACT
This project aims at the design and construction of a security lighting control system using a mobile
phone to serve as a remote control to control security lights. The device is made up of four main
units. The mobile phone which is serving as a transmitter for remotely controlling the security
lights. The GSM modem which serves as the receiver. A sim card is placed in the GSM modem and
all messages from the transmitter are sent to that mobile number. The microcontroller unit
processes the information extracts the message from the GSM modem and processes it. Then it
either puts on a pin or leaves it off. The switching unit is responsible for putting on or off the bulb
depending on the output from the microcontroller.
Upon completion of the project, it was tested and it worked properly. “light_on” puts on the bulb
and “light_off” puts off the bulb. Thus an effective and reliable security lighting control system
using mobile phone was realized.
