Abstract -
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.

1. INTRODUCTION Energy crisis is one of the major problems that the world faces today. The best remedy for this is not the increase in energy production, but the effective use of available energy. By properly monitoring our energy consumption and avoiding energy wastage, energy crisis can be reduced to a certain extent. But energy monitoring cannot be done efficiently mainly because consumers are not aware of their energy consumption. They will get an idea about their consumption only when the electricity bills are issued. In India, bill is issued only once in a month or two months. So the consumers will be in dark during this period of time about their energy usage. In this era of complete digitalization, no one will take the pain to go and check their electricity meter reading and compare it with the previous reading so as to get an idea about their consumption. This whole procedure has to be repeated several times in a month to efficiently control the energy usage. If consumers can check their energy consumption using their mobile phone or laptop instead of checking energy meter, it will be a great leap in the area of energy management. Since most of the

people are today 24*7 online, it will be really a boon if they can monitor their energy consumption online from anywhere on the globe. In this paper, we are describing a method of electricity energy meter reading using IoT concept. This is a PIC16F877A micro controller based design and implementation of energy meter using IoT concept. The Internet of things (stylized Internet of Things or IoT) is the internet working of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings, and other items embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data. In the proposed system, energy meters are connected to the internet using IoT concept. So there is a provision for the consumers to track their energy consumption from timeto-time so that they can control their consumption as they desire. This method is useful for both the consumer and the supplier. This system allows the supplier to disconnect the connection from a distant server in case the consumer fails to pay his/her electricity bill. This method eliminates the need of human power during disconnection and reconnection of the load. Another major advantage of this method is that it will inform the supplier side about any theft that is happening in the system.
2. PROPOSED SYSTEM In this system we are connecting energy meters to the internet i.e., IoT concept. This system eliminates the human involvement in electricity maintenance. The block diagram of the system is shown in Fig-1. The major components used in the system are PIC micro controller, energy meters (main energy meter and sub energy meter), interfacing circuit (optocoupler), relay and relay driver circuit, LCD display and a PC. The main energy meters as well as the sub energy meter are connected to the PIC microcontroller using an interfacing circuit. The interfacing circuit consists of an optocoupler. Optocouplers are used for providing optical isolation between an input source and output load just by using light. The basic design of an optocoupler consists of an LED that produces infra-red light and a semiconductor photo-sensitive device that is used
