| Summary: | Besides air and water, electricity is one of the most important elements
in human life nowadays. Electricity is needed to make all the electric and electronic
devices working properly. In Malaysia, Tenaga Nasional Berhad (TNB) is responsible
in supplying the electricity to all houses and premises. This paper describes the
development of power meter reading system with integration with GSM network.
The device created can help Tenaga Nasional Berhad to overcome their problems in
capturing meter reading as it incurs high cost. This project concentrates on designing
a system that can send meter reading from the user premises to Tenaga Nasional
Berhad office via SMS. The data transmitted will be received by the database system
to analyze, generate a bill and store the data. The implementation of the project
involved two different components; software and hardware. Microcontroller
PIC16F877A was used in this project and was programmed using Mplab software.
The program and the designed circuit were simulated using Proteus software to
make sure it was working properly. The prototype meter was connected to the
circuit to send the data using the GSM modem. At the final stage, the complete
system was integrated within its hardware and software to turn these two
components into one complete system. Currently, the prototype is suitable to be
apply in a rural environment due to the individual house is scattered randomly at
particular region. Thus the prototype could ease the authorized to manage the
electrical bill efficiently. |
