Design and Construction of a Micro Controller Based Smart Automated System for Controlling Various Home Appliances

Smart Home Automated System is an inexpensive technology. This study presents the overall design of Home Automation System (HAS) with low cost and wireless system. This system is designed to assist and provide support in order to fulfill the needs of elderly and disabled in home. Also, the smart home concept in the system improves the standard of living at home. The sensors, relays and web browser are used to control the home appliances. The main control system implements wireless technology to provide remote access from smart phone. The design removes the existing electrical switches and provides more safety control on the switches with low voltage activating method. The system intends to control electrical appliances and devices in house with relatively low cost design, user- friendly interface and ease of installation. Alternatively, SMART HOME AUTOMATED SYSTEM can provide higher level of security and convenience compared to traditionally used systems. The main objective of the current paper is to design and implement cost-efficient and reliable security, safety and automatic home system for protection and occupants’ convenience. If any hazard is being sensed like smoke, excess heat, unauthorized movements etc; the system warns the home-owner in real-time using Short Message Service (SMS). With this project, home appliances can also be controlled within and away from home, at the same time gives access to real time monitoring of the appliances and properties.
