Abstract

With the advancement in technology, the number of electronic devices in our day-to-day lives has increased to make life simpler. The rapidly advancing mobile communication technology and the increase in costs make it possible to incorporate mobile ethnology into home. This Project presents the development of GSM based control home system and the aim is to reduce electricity wastage. GSM (Global System Mobile Communication) module was used to receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as switch ON and OFF the home appliances. The system was integrated with microcontroller and GSM (Global System Mobile Communication) network interface using C Programming Language. The system is activated when user sends the short Message Service (SMS) to controller at home upon receiving the SMS command, the microcontroller units then automatically controls the electrical home appliances by switching ON or OFF the device according to the user order. The system has a delay of 2 minutes after the first call to initiate the next command. This project is made up of four vital units. These units are as follows: Global System Mobile Communication (GSM) Module Unit, Peripheral Interface Control (PIC) Unit Driver, Unit and a Power Monitoring and Control Unit. The GSM unit is a GSM transceiver which gives the system access to the GSM Sever Provider. The Peripheral Interface Control (PIC) is programmed to carry out the OFF/RESET operation according to the Global System Mobile Communication (GSM) commands while the Driver and Control Unit consist of capacitors, resistors, diodes, regulators and electromagnetic relay is to effect power switching. The GSM Home Base Automation System can perform various functions such as to switch ON and OFF the home appliances such as Gate opening with Card, Light, Air Conditioner, Fan and Television and Radio appliances. The major component that performed the Power Control of 220V main supply and the Automatic Voltage Regulation (AVR) is the automated electromagnetic relay. The project was realized.
