WebThe arduino takes the pulse from the energy meter, calculate units and displays the reading on the LCD. The reading is store in built in EEPROM so at the power failure it continues the calculating reading. The reading of the energy meter is also sent to the cell phone of the user by a message through GSM modem. WebThe GSM based power theft control system is developed. We used Proteus software to analyze and estimate what the hardware will look like. Mainly this system consists of a microcontroller, energy meter, current transformers, LDR, relay, LCD, and GSM module. chips old show
