SMART KEY FOR MODERN HOUSE

AIM:

The aim of this project is to provide controls for the home appliances by using the GSM technology.

PURPOSE:

The purpose of the project is to control the home appliances remotely. This system provides ideal solution to the problems faced by home owners in daily life. The system is wireless therefore more adaptable and cost-effective.

DESCRIPTION:

Short Message Service (SMS) is defined as a text-based service that enables characters to be sent from one mobile phone to another. In a similar vein to email, messages are stored and forwarded at an SMS centre, allowing messages to be retrieved later if you are not immediately available to receive them. Unlike voice calls, SMS messages travel over the mobile network’s channel. Using the convenience of SMS, this project lets us remotely control equipment by sending plain text messages, such as "pump on", "aircon off", and “reset" or "light1 on" – all of which can be pre-programmed into the controller and easily remembered later. It can control up to eight external devices.

The 8 bit microcontroller is used to control the whole circuit. It read message from the Mobile phone and control the devices according the received message. We can add some additional password as starting words of the sms. The microcontroller will take action only when the password is matched, otherwise the sms will be ignored. Hence it becomes secure also that any unauthorized person cannot control the devices. There are many advantages of sms over other wireless controlled systems. Although it does not work in real time, it is very much useful for the system where the time delay is not the important factor. It is globally controlled i.e. we can control our devices from anywhere in the world. Since mobile phone is now available to everyone, it is very much cost effective.
