ABSTARCT :
With the increase in the consumption of energy and population, there is a great need to conserve energy in every way possible. The inability to access and control the appliances from remote locations is one of the major reasons for energy wastage in Ghana. This project presents the development and implementation of a Global System for Mobile Communication (GSM) based remote control system for electrical appliances and lighting that enables complete control of the interface on which it is based. GSM Shield was used for receiving short message service (SMS) from the homeowner?s mobile phone that automatically enables an Arduino microcontroller to take the necessary actions like switching OFF and ON electrical appliances such as fan, light, air- conditioner, supply mains and so on. Basically, it reads the SMS and acts according to the message. Similar products commercially available are Internet dependent and so lack the true sense of real mobility and security. However, the present GSM based remote control system allows the homeowner to control household appliances from anywhere using the mobile phone and also prevents unauthorized access to these appliances. Crucial to the present system is the provision of security on detection of intrusion via SMS using GSM technology. This GSM based HACS is recommended for implementation in every home to tackle the rampant energy wastage in Ghana.
EXISTING SYSTEM :
? It is believed that the lack of adoption is due to the lack of extensibility, cost, and ease of existing systems.
? Pre existing network protocols UDP, SNMP will function same way as expected on both wireless and wired networks. .
? These are designed in order to modify the existing normal refrigerator as a smart refrigerator which enables the user to save a huge cost.
? This system includes existing two modules and one clouded module which will be available at any time and maintaining a copy of the system information up to date.
DISADVANTAGE :
? This client/server mechanism uses different protocols to convey messages and to control signals through the internet have explained about IOT and Cloud computing can work together to address the big data problems.
? Unit test levels were important and very effective since most of the problems have been identified and eliminated in early stages of development.
? The Connectier team faced so many technical problems from designing phase to implementation phase of the system.
? Most of the researches mentioned above contain two modules: hardware module and software module for communication.
PROPOSED SYSTEM :
• SMS is the best solution for communication in a power failure proposed a GSM based system in which the user sends a sms command which is identified using a microcontroller.
• The major reason behind choosing MQ-2 Smoke Sensor for our proposed smoke detection module is its sensitivity to smoke and to plenty of other flammable gases such as LPG, butane, propane, methane, alcohol and hydrogen.
• Firebase real-time database system has been used as the database of this system to make sure that the users will get a real time experience of observation of their home appliances. Proposed Home Automation System will help to improve the standard of living at home and allow increasing work efficiency in future.
ADVANTAGE :
? SMS is used as a means of monitoring and controlling systems because is the easiest and the most available technology.
? Though the HACS technology seem promising, the major task of improving performance has attracted least research attention.
? Technology has been ever evolving, and as a result, new means are being developed for easier and safer control of electrical devices for more efficient power management at homes and workplaces.
? Most people inevitably tend to leave their lights, fans and other appliances on when leaving their homes resulting in energy wastages and inefficiencies.
? Home automation or Intelligent/Smart home (SH) means automating daily tasks of electrical devices used in homes.
