Controlling and Distribution of Prepaid Electrical Services Using Wireless Sensor Network

Abstract

In this paper, we present the controlling and distribution of electricity from a micro grid deployment in rural areas based on Wireless Sensor Network. The objectives of the project is to minimize the queue at the electricity billing counters , to restrict the usage of energy ,reduce the loss of revenue due to power thefts.The microcontroller is used as heart of the system. The main unit contain a ZIGBEE module which is connected to PC for controlling the electrical lines and the status of usage power will be displayed on PC. The consumer unit contains LPC2148 GSM(Global System for mobile communication) ZIGBEE module relay energy meter LDR and LCD.Energy Meter pulsing led as input to the LDR sensor which is interfaced to microcontroller, proportional to the energy consumed which is calculated by using counter microcontroller. A relay is used to make connection of load.The GSM technology is used so that the consumer would receive messages about the consumption of power (inwatts) and if it reaches the minimum amount, it would automatically alert the consumer to recharge. When balance is zero GSM modem will send SMS to customer for further recharge of energy units and power cut off until recharge is done. The work system adopts a totally new concept of “Prepaid Electricity”.
