GSM Based Automatic Energy Meter Reading

The purpose of this project is to remote monitoring and control of the Domestic
Energy meter. This system enables the Electricity Department to read the meter readings
regularly without the person visiting each house. This can be achieved by the use of
Microcontroller unit that continuously monitors and records the Energy Meter readings in
its permanent (non-volatile) memory location. This system also makes use of a GSM
modem for remote monitoring and control of Energy Meter.
The Microcontroller based system continuously records the readings and the live
meter reading can be sent to the Electricity department on request. This system also can
be used to disconnect the power supply to the house in case of non-payment of electricity
bills. A dedicated GSM modem with SIM card is required for each energy meter.
The major building blocks of this project are:
1. Microcontroller based control system with regulated power supply.
2. GSM Modem for remote communication
3. Electromagnetic Relay and Relay Driver for Power Supply Control.
4. Digital Energy Meter.
5. LCD Display to display the meter readings.
