Design and Implementation of GSM Based Automation of Household Appliances
In this paper, GSM Based Automation of Electrical Household Appliances is presented. The problem of paying huge electricity bills generated by various household Electrical Electronic appliances at home/office is alarming. To help reduce the total number of energy use and amount to be spent on electricity bills, GSM Based Automation of Electrical Household Appliances is proposed. The system is designed to allow the user to control the switching ON/OFF of his/her electrical home appliances via mobile phone anywhere at any time. The system consists of hardware and software .Any household appliances can be switched ON by sending an SMS with the keyword 'LL1 or LL2 or LL3 .etc. from the user's mobile phone to the receiver panel at home, the receiver antenna picks the signal and forward it to microcontroller which decodes the keywords and command the instructions to trigger any device connected to the system ports. When the device (s) is/are switched ON, the system sends a feedback message back to the user stating the status of the device(s) Also user can switch OFF any of the appliances by sending an SMS with the keyword 'LL0' and the instruction would be carried out and message returned back to the sender.The system is implemented program written and tested with accurate results.
