Project Summary

With advancement of technology, things are becoming simpler and easier for us. Automatic systems are being preferred over manual systems. The purpose of this project is to design and construct A GSM based home automation using AVR. Using GSM networks, in this project a home power control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals. The system has a delay of 2 two minutes after the first call to initiate the next command. This project is made up of four vital units. These units are as follows: GSM module unit, peripheral interface control (PIC) unit, driver unit and a power monitoring and control unit. The GSM module is a GSM transceiver which gives the system access to the GSM service provider. The peripheral interface control (PIC) is programmed to carry out the OFF/ RESET operation according to the GSM commands while the driver and control unit consist of capacitors, resistors, diodes, regulators and electromagnetic relay is to effect power switching. 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 and a light bulb was literarily used for the demonstration; it was automated using the system developed.

Project Objectives

The objective of this project is

• To implement a low cost, reliable and scalable home automation system
• To construct a circuit that can be used to remotely switch on or off any household appliance, using a microcontroller to achieve hardware simplicity, from any phone to toggle the switch state.

Project Implementation Method

Initial approach to project designing and execution is to gather enough information in order to help speed up the operation once the actual work commences. Methodology is the study of how to perform scientific research. It is the part of any analysis or research that is used to find out what type of data is maintained, what fact to find and look for, how to find them and how to record them for usage. In order to achieve these, Structured System Analysis and Design Methodology (SSADM) were used. This is because; SSADM is an internationally accepted software engineering model mainly used in most result oriented analysis.

Benefits of the Project

Design and construct a home automation system that will remotely switch on or off any household appliance connected to it with the use of a mobile phone; taking lightning as a case study.

It is also helpful for the less educated cluster of people as the interface is very user friendly.

Technical Details of Final Deliverable

GSM is a cellular network, which means that mobile phone can be connected to it by searching for cells in the immediate vicinity. GSM network operate in four different frequency ranges. Most GSM network operates in the 900Mh2 or 1800 MHz bands. In 900 MHz band, the uplink frequency band is between 890- 915 MHz and the downlink frequency band is 935-960 MHz. In the 1800mz band, the uplink frequency is between 1710-1785 MHz and the downlink is between 18051880Mh2. also in 1900 MHz band, the uplink frequency band is 1850 Mhz- 1950 MHz. In GSM 900 MHz, the band allocation is 25 MHz band width which is subdivided into 24 carrier frequency channels, each spaced 200 kHz apart. Time division multiplexing is used to allow eight-fall rate to sixteen half-rate speech channels per radio frequency channel. There are eight-radio time slots (giving eight burst penods) grouped into what is called TOMA frame. Half rate channels use alternate frames in the same time slot. The channels data rate is 270 833kbit/s and the frame duration is 4.615ms. The transmission power in the handset is limited to a maximum of 2 crafts in GSM 900 and I waH in GSM 1800/1900.GSM has used a variety of voice codes.
