IoT Based Energy Meter Reading, Theft Detection and Disconnection

This is a PIC16F877A micro controller based design and implementation of energy meter using IoT (Internet of Things) concept. This design eliminates the human involvement in electricity maintenance. The energy meters are connected to the PIC micro controller through an interfacing circuit. The optocoupler sensor gives an interrupt each time the meter LED ashes to the programmed PIC micro controller. The readings of the main energy meter and sub energy meters are compared so as to identify the theft status. Whenever there is discrepancy in the two values, a message that theft has occurred will be displayed in the LCD display as well as in the web page. We can access the web page from anywhere on the globe at any time using the consumer number provided by the supply authorities. So the consumers can easily track their energy usage so that effective monitoring of power consumption is possible. The hardware interface circuit consists of PIC16F877A micro controller, MAX232, LCD display, and optocoupler
