This paper introduces microcontroller based over voltage and undervoltage protection of domestic appliances and monitoring them through GSM. It starts with the importance of using micro controller in controlling voltage condition, it covers up the aspects why this method of protection is better and simpler than conventional method. We used ATmega32 microcontroller and Sim 900A GSM module to get the status of the supply voltage, be it the time of tripping or at any instant by sending specific text to GSM module. We have also added LCD to get voltage value at any time and status during abnormal condition.There is a limit set for a range of voltage that would be considered normal working condition.Microcontroller will check this condition and trip load if it does not satisfy.Under voltage and overvoltage are one of the major issues prevailing at domestic level that can affect electrical appliances. This method of protection can curb this issue significantly.
