GSM based Monthly Electricity Energy Meter Billing and SMS upon GSMwith User Programmable Number Features together with Onsite Display to the user
The project is designed for reading electrical energy consumed in units and in rupees to display on an LCD screen to the user. This data is also provided to the electrical department using GSM technology for billing purposes. Owing to high electricity cost these days it becomes necessary for the consumer to know as to how much electricity is consumed to control electricity bill within his budget.
In this proposed system, the consumer will get his energy consumption data on real time basis on a LCD display. The same data is sent through GSM modem to the electricity department via SMS. A microcontroller of 8051 family is interfaced to the energy meter to get the Watt Hour pulses.
The microcontroller then processes these pulses according the program written in it, to calculate the units consumed and cost involved. Further it gives command to the SIM loaded GSM modem for sending the data to the electricity department via SMS.
Further this project can be enhanced by to control the electrical appliances remotely via SMS. Also, the electricity department can send the monthly bill amount over SMS to the receiving unit for consumer information.

"I live in Hyderabad, a place that is known for engineering colleges. Went with frnd and bought a set from Ameerpet(tht hs rdymade stuff like this) and it failed just b4 viva. Thats when we got this thx to a senior who is sorta like a geek.. and let me tell u.. Its one reason why me and my frnds got thru the final sem. Works great and is useful too later.. "Ravi Teja

"A must-buy. It helped me practice in real time and learn how to make a project by looking at an actual workable unit. (fyi - you get a fully built unit and another full set of components to build another by yourself) so it was great value for us. We shared the costs by 3 (our team for the project) but i got to keep my unit as the other two kept the original. Showed it for my on-campus and got thru too becuase it not just looked neat and profesionally bt worked great later. (still have it in my room, now working with GE in Bangalore) "Anusha

"We have used it for our institution - it is available in lab and has been good for explaining various models in live during class. Strongly suggest every college dept to have it for labs as it is working well - even with regular use at lab for more than 1 year. Note:We got the unit complementarity before launch in 2014 and have later purchased few batches. The team behind it is professional and know what electronics students need and i am writing this review on their request on 13/05/2016"Mr. Ramesh Kumar Jha

Q: What is GSM?
A: It stands for Global system for Mobile Communications. It is a communication standard using time division multiple access technique.
Q: What is the frequency range for GSM?
A: GSM frequency range is 900MHz
Q: How can I feed the mobile number?
A: By giving a missed call to the SIM number of the GSM interfaced to the controller, one can feed the mobile number.
Q: How energy tariff is calculated?
A: Energy tariff is calculated by using digital pulses from energy meter, an appropriate program calculates the pulses and converts it in energy units and then calculates the per unit cost.
Q: Which microcontroller is used in this project?
A: A 40 pin microcontroller from 8051 family is used in this project.
Q: Which energy meter used?
A: A 230VAC, 5-20A digital energy meter is used.
Q: How exactly is the pulse reading taken from energy meter?
A: From any digital energy meter internal circuit that delivers one pulse per a certain fraction of one unit is taken from its blinking LED points.
Q: What is the formula for calculating smoothing capacitor value?
A: There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q: Why did you set sending of SMS for only 10 pulses?
A: We can write the program for monthly or weekly or daily basis, but we cannot wait for that much of time to see the output or we cannot wait for 3200 pulses which make 1 unit. Also here our load is 100W bulb so we have to wait for 10 hours to get 1 unit. So we go for 10 pulses to send SMS.
