GSM Based Electrical Control System for Smart Home Application
GSM Based Electrical.rtf (Size: 4.56 MB / Downloads: 25) Abstract This paper presents the development of GSM-based control home appliances for smart home system. The main aim of the prototype development is to reduce electricity wastage. GSM module was used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch ON and OFF the home appliances such as light, air-conditioner etc. The system was integrated with microcontroller and GSM network interface using assembly language. MPLAB software was utilized to accomplish the integration. The system is activated when user sends the SMS to controller at home. Upon receiving the SMS command, the microcontroller unit then automatically controls the electrical home appliances by switching ON or OFF the device according to the user order. In other word, it read message from the mobile phone and response to control the devices according to the received message. The prototype has been successfully developed and it could provide an effective mechanism in utilizing the energy source efficiently. Introduction The development of digital information has led the rapid change in human lifestyle. The use of electricity is very important as one of the main source of energy that is vital in today modern life. Some kinds of mechanism using available technology could be used to reduce wastage in electricity usage. Thus a prototype based on a microcontroller device using SMS is developed. It can automatically control any electrical equipment at home remotely using mobile phone. Hence the electrical energy saving in daily life can be made more efficient and effective. Related Work This section provides a previous study of related work regarding the application of SMS services in a various fields. Some previous researches have been studied to gain more information about current existing GSM control system that was previously implemented. It is necessary to know and understand how the software and hardware were used in the SMS controlled system development. This is to ensure that the study that currently being conducted contribute at certain level of application thus it become more efficient and practical. Project Work This section describes the methodology used to perform the development. The flow of the development is depicted in Fig. 1 Figure 1 illustrates the flowchart for overall project development. The initial process in flowchart involves in a research regarding the project background and literature review. Based on research, the problem is formulated as well as objective and scope of the project has been defined. The next process is to plan how the project or problem formulated be organized and possible solution are arranged systematically. The project is then divided into two parts; hardware design and interfacing. The Proteus 7.0 software has been chosen in the circuit design, while the MPLAB IDE is to program the PIC using assembly language. MAX232 Circuit This MAX232 chip was used in the circuit for interface between the Receiver module (RX module) and the computer. This is only to display the AT command. Utilizing MAX232 enables communication between the computer and the receiver module (RX module) via serial port. The Max232 also acts as a buffer driver, converting the digital logic 0 to 5 V receiver signal into the RS232 standard –12 to +12 V signal. The MAX232 requires five external 1uF capacitors, which are used to generate the +12 and –12 V swing. Relay Relay is used in the circuit because it is an electrical operated switch that connected to the output. A relay in this system is an electrical switch that opens and closes under the control of PIC16F873A microcontroller. The relay switch connections are usually labeled as Common (COM), Normally Closed (NC) and Normally Open (NO). The circuit is connected to COM and NO if it is switched to ON when relay coil in ON while to switch OFF the circuit connect the COM and NC together and then the relay coil is in OFF state. Therefore, the output was connected to COM and NO. As a result the relay Conclusion The prototype was successfully developed and met the three stated objectives. The system can automatically switch ON and OFF the extension and lamp remotely using SMS. The integration of software and hardware has performed a good task in producing the SMS system. However, there are several weaknesses had been identified which can be further improved in the future such as the system could |
