The main aim of this project is to monitor any power drawn before the energy meter which is treated as power pilferage .Once such power is detected it results in disconnection of the power supply to the consumer and an SMS is sent to the control station to take penal action on the fraud consumer.

Electricity is a necessary energy for our daily life; with the increasing demand of electricity, power theft is also increasing that affects power sector across the whole country.

The objective of this project is to design a system that avoids such situation . For this project, an 8051 family of microcontroller is used to continuously monitor the load consumption before and after the energy meter . Any difference noticed between the input power and the output power from the meter is detected by a special CT feeding a signal to a through an Opto-coupler.

In demonstrating the project function , a fixed load of 100 watt lamp is connected duly from the output of a standard energy meter and a provision is kept with a lamp holder that is wired before the meter connection .The moment any load is connected to this lamp holder the sensing takes place for action as described as above. It triggers the generation of an SMS, and then the status of the system is also displayed on an LCD.

The information, in the form of a message fed from the microcontroller via a level shifter IC and RS232 link, is sent to any cell phone through a GSM modem. The number to which the message is sent is auto saved onto the microcontroller by means of a missed call made from the user.

The project can be extended further to larger current loads and send the energy consumption details remotely on smart mobile phone by using Bluetooth technology.

    I was searching my project title in google then, i got to know about edgefx. I have decided to buy project from edgefx because my project is similar to the edgefx project that is why i have purchased project from edgefx. I like most about edgefx kit was PPT’S. the kit was delivered in time with right components. the team has helped me in purchasing the project and they also helped me in technicals issues.. Provide more and more advanced projects.. i want to give reference to my juniors.
