What is a GSM technology?

The term GSM stands for “Global System for Mobile communications” and it is a digital cellular technology used to transmit mobile voice as well as data services. It supports voice calls and the speed of the data transfer ranges up to 9.6 kbps, together with the broadcast of Short Message Service (SMS). The operating frequency of GSM ranges from 900MHz to 1.8GHz bands in Europe country and in the USA, it would be 1.9GHz and 850MHz bands.In many Lain American countries and in Australia these services are also transmitted through the 850MHz spectrum.

Programmable Energy Meter

The programmable energy meter is an electrical instrument used to measure the amount of electrical energy used by the buyers. These instruments are used in every place such as homes, organizations, industries to control the electricity consumption by different loads like lights, fans and other usages. Prepaid electricity meters are most interesting types of meters. Watt is the basic unit for power and 1 thousand watts are equal to one kilowatt. If we use 1KW in one hour, it is measured as one unit of energy consumed. These energy meters measure the immediate voltage and currents, the product of these two gives instantaneous power. This power is integrated over a period which gives the energy utilized over that time period.Please follow the below link for: Three Types of Energy Meters

GSM based Programmable Energy Meter with Bill Estimation Display

The main goal of this project is designed to read the electrical energy paid in units and also in rupees to show on an LCD display.

The hardware requirements are; 8051 series Microcontroller, Level Shifter IC, GSM module, LCD, LED, Crystal, Resistors, Capacitors, Diodes, Transformer, Regulator, Opto-Isolator, Energy Meter, Lamp. The software requirements are; Keil compiler, Language: Embedded C or assembly.

Nowadays, the cost of an electricity has become an essential for the customer to know as to how much electricity is spent to control electricity bill in his budget. In this project, the customer will acquire his energy consumption data on a real time base on an LCD display. The similar data is sent through a GSM modem to the electricity department through an SMS. An 8051 family Microcontroller is interfaced to the programmable energy meter to acquire the Watt Hour pulses.

Based on the program, the Microcontroller processes the pulses to analyze the units spent and cost involved. Further, it gives a command to the SIM loaded GSM modem for transferring the data to the department of electricity through an SMS.

Further, the proposed system can be developed by controlling the loads remotely through an SMS. Also, the department of an electricity can

Further, this project can be enhanced by to control the electrical appliances remotely via SMS. Also, the electricity department can send the amount of the monthly bill over SMS to the receiving unit for user information.

This is all about GSM based energy meter with bill estimation display to the user. We hope that you have got a better understanding of this concept.
