2. Introduction Electricity is the driving force behind the development of any country. With the rapid increase in residential, commercial, and industrial consumers of electricity throughout the world, it has now become imperative for utilities companies to devise better, non-intrusive, Environmentally - safe techniques of gauging utilities’ consumption so that correct bills can be generated and invoiced. Nowadays, Wireless communication has become ubiquitous, hence we have tried to make a system to read energy meters with less human efforts using wireless technology. Wireless Energy Meter Reading System

3. Objective • In India, large number of employees are hired to read meter. Using this system very less human effort will be needed to read meters. • Meter can be read from a far distance from the consumer’s place. • There some people don’t like unknown person entering their homes, this dissatisfaction can be solved by using this system.

6. Working • In this project we are going to measure energy meter reading through wireless technology. • In the receiver unit identification number of all energy meter are saved. Then unit sends the signal for reading purpose. In the receiver section there is one computer, one keyboard and one wireless card with antenna. • Transmitter section contain microcontroller. When this unit receives the signal from master unit then it will connect with the master unit wirelessly. Wireless Energy Meter Reading System

7. Then master unit ask for meter reading. At that time meter reading are also displayed on LCD display at meter side. Microcontroller sends the data to the master section. • We can see the real time operation because the same data will be received by the master side. So we can measure the meter reading fast and accurately. Wireless Energy Meter Reading System
