This project aims to design a circuit which helps the consumer in taking care of his/her electrical energy consumption. It affects the consumer’s bill severely. To make the consumer aware and to control the excess energy consumption, this paper introduces, “ENERGY CONSUMPTION INDICATOR”. This system will intimate to the consumer about his /her previous set energy consumption value once the meter reached to that value. It will also alert the limited voltage, power factor, frequency. In this way, the consumer made aware of his/her energy consumption, Once the maximum threshold value is reached, the notification sent to the consumer by sending SMS to his /her registered mobile number. It is not only benefits to the consumer and, it also benefits to the government in the point of reducing the power consumption and subsequent reducing of unusual power usage.

It is the prime mover of the many of the electrical components. The future is based on the electricity so we need to save it, because they will not available for long days. “ENERGY CONSUMPTION INDICATOR” mainly aims at households to bring their electricity bill down with the help of the energy consumption alert system and also alert for power factor, as well as frequency. Energy meters being deployed at homes and industries are used for reading the power, i.e. energy being consumed. Each consumer must fix a customized threshold value of unit (depends on his/her own interest or bill rate), power factor, frequency. If the value reached to the above rated threshold value, the notification sent to the consumer to his /her mobile number with the help of a (mobile application or reports are given periodically to the specified mobile number through website). We can install this indicator in any place like home, industries and where we want to monitor the electricity. Customer can fix the threshold value of energy for their requirement. ENERGY CONSUMPTION INDICATOR is used to continuously monitor the meter reading. Major components used in this project are ARDUINO Board, Raspberry Pi, Energy meter circuit (PZEM004T) and the load. ARDUINO and Raspberry Pi is a credit card sized minicomputer and act as a fast processor system. It is the central unit of this project and is connected energy meter circuit through various ports. The overall operation of the proposed system is discussed in the following sections. 2. LITERATURE SURVEY Literatures [1], [2], [3], [4], [5] research work done by scholars in this domain of wind power consumption area. where they discussed about monitoring of energy reading. Transaction of energy conversion [6] here they used to find the track of energy conversion. For easy communication between EB officer and consumer readings [7] they used the GSM based power management with reduced cost. For monitoring the electrical energy in home appliances [8] they used wireless sensor and actuator network. This helps the customer to monitor the unit of energy consumed. A prepaid energy meter using mobile communication [9] they use a prepaid card communicating with energy meter, where the cost is deducted using prepaid card for unit of energy consumed by he /she, Once the prepaid card is out of balance, the load of the consumer is disconnected from the utility supply by the contactor. 3. SYSTEM ANALYSIS The various literature studies that were done by the various people, helps us to develop a new technique for controlling and monitoring the energy consumption. 3.1. Issues in the existing system i. No indication about power factor i.e. power factor lagging situation. As a result of this, the slab rates are doubled and this leads to a high bill amount.
