Abstract:
The general objective of this study is to design controlling mechanism that prevents wastage of
excessively consumed energy due to light bulbs in home using GSM Network. GSM module was
used for receiving SMS from user’s mobile phone that automatically enable the controller to take
the action such as to switch ON and OFF the light bulbs. The system used SIM900 GSM Module
which allows users to effectively control light bulbs from wherever by sending SMS (Short
Message Service) to the device. ATmega328 microcontroller which is embedded in Arduino Uno
board, which was used to communicate with SIM900 GSM Module and the relay module to carry
out the ON/OFF operations received from user’s mobile phone. The software used to this system
Arduino IDE to write the codes which makes the communication with microcontroller;
programming language C, and the Proteus software is used to simulation. When a user sends an
SMS to the controller at home or at work, the system is stimulated. The microcontroller units
automatically control the light bulbs by turning the gadget ON or OFF in response to receiving
the SMS command. The system has been successfully developed and it could provide effective
mechanism in controlling the light bulbs efficiently as result the excessively wastage of power is
reduced. This research provides a modern approach to our society to control the light bulbs and
improves the traditional method of switching. The evaluation indicates that as the user perform
successfully; it reduces monthly bill payment by more than 50% from the previous consumption.
The system has evaluated in different ways, the first one is measuring the performance of the
system in terms of speed and the second evaluation is undertaken using assessment and
collecting data from the user to show the effectiveness of the method. As indicated from
simulation result, the execution time of the system is very fast when the commands are sent from
user to take action & the time taken to perform the action is very minimum
seconds/milliseconds/.The assessment result indicated that, when the user implement this method
in their home, they reduce wastage of power highly and as result they minimize monthly bill
payment by half of the earlier payment.
