Electricity is one of the most important blessings that science has given to mankind. It also had become a part of modern life and cannot think of a world without it. People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
As the technology is developing day by day and dependencies over the electrical appliances increases, the usage and requirement of electricity also increase rapidly. As a result, it had become quite difficult for the authorities to collect the electricity bill. The main aim of this project is to design a system that reduces the usage of electricity and which helps in bringing transparency between the Electricity Board and the customers. In this proposed system, the meter needs to be recharged similar to a mobile phone, payment for recharge can be done on the app and can monitor the amount deduction, energy consumption, frequency, voltage, and power fluctuation. The user also has the power to stop the flow of electricity from remote locations if the electricity is not consumed. The energy measurement and billing system are automated. The work system adopts a totally new concept of “Prepaid Energy Meter”.
BENEFITS OF THE PROPOSED SYSTEM:
- To avoid more consumption of electricity.
- Reduction of man-power.
- Increase the accuracy of the meter reading.
- IOT Based Energy Monitoring System to monitor the Real Power and other Energy Parameters
- Know your energy bill before given by Discom and get the breakup of energy share of different equipment’s.
- No need for manual labor for collecting monthly power consumption data on individual houses or industries and power generation companies
- Consumers can keep track of their energy consumption and may able to cut down power consumption to save on the bills.
Presently in India, the system of electricity billing is done manually. So the chance of occurrence of errors is high. Also, we need to wait in a queue for a long time to pay the bill on the electricity board. Hence, It is a time-consuming and labor-consuming process. In case, if we are not able to pay the bill on time, we are forced to pay the fine along with the bill. These problems can be overcome using a prepaid electricity billing system. So here we are introducing prepaid electricity billing using GSM technology. In this, the consumers can use even their cell phones to recharge the system. And also we are having prepaid recharge coupons to recharge their account
This paper proposes, a real-time Raspberry Pi 2 based prepaid electricity billing meter to monitor household electrical appliances. This Completely automated prepaid electricity meter is used to measure the voltage, current, power, and finally number of units consumed by the customer. The proposed system comprises intelligent energy distribution with fixed power supplied by Electricity Board (ED). The consumption of power varies from user to user; the variation of power consumption is monitored and controlled by an automated electricity billing system. Moreover, monitoring of home appliances is developed either manually, remotely, and with the help of GSM. The fundamental goal of this paper is to give minimal expense and adaptable computerized prepaid power meters. Power bill naturally ships off client through GSM Module and gives an alarm message to the client. This computerized prepaid power meter can gather the number of units devoured by the client at their separate house.
The GSM innovation is utilized so the buyer would get messages about the consumption of power (in watts) and if it reaches the minimum amount, it would automatically alert the consumer to recharge. The power utility can recharge the prepaid card remotely through GSM/SMS mode based on customer requests. An earlier charging will undoubtedly get rid of the issues of neglected bills and human mistakes in meter readings, consequently guaranteeing defended income for the utility.
- Raspberry Pi 2:
Raspberry pi is a Linux operating system. The Raspberry Pi 2(2835) consists of a model B. It is a 32-bit processor and credit-size computer system. RAM size of Raspberry Pi 2 Model B+ is 1GB. A 900MHz quad-core ARM cortex-A7 CPU (Central Processing Unit). It is 40 GPIO pins.
- 71M6543F Microcontroller
71M6543F microcontroller is the 4th generation of polyphase metering Systems-on-chips (SoCs). Its Clock frequency is 5MHz. The 71M6543F of RAM is 5KB, ultra low power operation inactive, battery modes, 64KB of flash memory, and 22-bit delta sigma ADC (analog to digital conversion). It can be programmed with code and data during meter operation
A relay is designed as an electrically operated switch. Many relays operate with an electromagnet to mechanically operate a switch. Relays functions where it’s necessary to regulate a circuit by a low-power signal. This is performed with complete electrical isolation between control and controlled circuits, or several circuits that should be controlled by one signal. This 5V Relay is an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V. This 5V RELAY is controlled directly by Microcontroller
- Current Transformer:
Current transformer (CT) is a type of transformer that is used to measure AC Current. It produces an alternating current (AC) in its secondary which is directly proportional to the AC current in its primary. Current transformers, together with voltage transformers (VTs) or potential transformers (PTs), which are designed for measurement, are known as instrument transformers.
A Buzzer or beeper is an audio signaling device. Whenever the air pollution goes above the threshold level the Buzzer starts beeping indicating Danger.
- GSM MODULE:
GSM is a global system for mobile communication. Its frequency range is 850-1900 Mhz. It is a wireless communication system between the Raspberry pi2 to Mobile phone and requires a SIM (Subscriber Identity Module) card like a mobile phone to achieve communication with the network.
ADVANTAGES OF THE PROPOSED SYSTEM:
- User friendly
- Can be Controlled from anywhere in the world
- Daily energy limit
- Reduce financial risk
- Better customer service
We are living in a technology-based society where we have lots of innovative ideas day by day. These new innovations in IoT communications-based projects, strive constantly to share and gather insight on the latest trends in the industrial IoT landscape. In conclusion, the objective of this project is to build a system that can monitor power parameters by the GSM Module and IoT. Here we design an IoT-based Prepaid Energy Meter system for real-time monitoring of power for the users using GSM technology.
. This system is capable of measuring and analyzing the electrical parameters such as voltage, current, active power, and energy consumption of loads. Our proposed system utilizes an energy meter with a microcontroller system to monitor energy utilization utilizing a meter. Thereby helping the consumer to track their energy consumption and may be able to cut down power consumption to save on the bills. Also, there is no need for manual labor for collecting monthly power consumption data on individual houses or industries and power generation companies. Thereby provides real-time monitoring and a rapid alert system to produce an efficient platform for saving energy.
