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 systemusing mobile phone was realized.
