Abstract :

In modern days, we must use various high–tech machineries and equipments to get our jobs done and make the life easier. These machineries should be controlled by the home–owner from any location as the homeowner might be away from home at workplace or traveling in a different place in the weekend. Thus a system of remote monitoring and controlling are very much necessary. Smart home is one of these types of system equipped with home appliances which we wish to control smartly from anywhere. Some products are commercially available which allow remote home appliance controlling through internet which is undoubtedly emerging. We designed and constructed a cell phone controlled house automation system. The system allows users to send commands from their cell phones to control both a LIGHT and cooler & various other devices. Commands are sent via a cell phone’s numeric code dialing capability. The system is equipped with DTMF decoder and relay driver for controlling any appliance. The design is modular hence we can expand the system for more switches. The main advantage of the circuit is its vast range it can control any device from anywhere in the world. The reliability of the circuit is greatly enhanced due to availability of low cost cell phones and interfacing connectors. Our design met all the intended objectives however; improvements can still be made in the algorithm to make it more users friendly and reliable. Overall, the final price of implementation was kept low due to simplicity of the circuit. All the components are locally available. However, if this product were to be produced and sold, further cuts would be needed to make the end price competitive.
