GSM Based Electrical Load Control System for Home Applications

Abstract

A method for controlling electrical home appliances via a mobile phone network is described here. Alarmingly high electricity bills are being produced by a wide variety of Electrical & Electronic appliances in the home. GSM-based automation of electrical home appliances is proposed to help cut down on energy consumption and associated costs. The user can turn on and off the power to his or her home's electrical appliances from anywhere using a mobile phone connected to the system. Both physical and digital components make up the system. By sending an SMS with the keyword #A.fan1.on* or #A. 1ight1.on* or #A. 1ight2.on*. … etc.’ from the user's mobile phone to the receiver module at home, the antenna will pick up the signal and forward it to the microcontroller, which will then decode the keywords and command the instructions to trigger any device connected to the system ports. When a device (or devices) are turned on, the system will provide the user with a status update via a feedback message (s).
