Energy Meter Billing with Load Control over GSM with User Programmable Number Features
The main objective of the project is to develop a GSM based energy meter reading system and load control through SMS. Electricity department sends employees to take meter reading every month, which is an expensive and time consuming job. The proposed project provides a convenient and efficient method to avoid this problem.
The electricity department and the user can get the readings of the energy meter of consumers via SMS. The loads can also be controlled by the user of this system via SMS using this project.
A microcontroller input is effectively interfaced to a digital energy meter that takes the reading from the energy meter and displays the same on an LCD. The reading of the energy meter is also sent to the control room by an SMS via SIM loaded GSM modem.
This GSM modem can also receive commands from the cell phone to control the owner’s electrical loads. It uses a standard digital energy meter that delivers output pulses to the microcontroller to perform counting for necessary action. On receiving command it can switch ON/OFF the loads.
Further this project can be interfaced with a non volatile memory IC like EEPROM along with a keypad so that the user the change the mobile number as per the requirement.

"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: GSM stands for Global System for Mobile communications. It is a communication standard using time division multiple access technique.
Q: What is the frequency range of GSM operates in this project?
A: Frequency range of GSM is 900MHz.
Q: How can I feed the mobile number?
A: One can feed the mobile number by giving a missed call to the SIM number of the GSM modem.
Q: Which energy meter is used?
A: 230VAC, 5-20A Digital energy meter is used
Q: How energy tariff is calculated?
A: An appropriate program in the microcontroller uses the pulses from the energy meter, to calculate the energy unit consumed and hence the per unit cost.
Q: Can it be possible to switch on the lamps?
A: Yes it is possible by sending an SMS.
Q: Is it possible to switch on the lamps?
A: Yes, any electrical load up to 200W can be used.
Q: Which microcontroller is used in this project?
A: A 40 pin microcontroller from 8051 family is used in this project.
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: What to do when the lamp fails and what is the maximum lamp rating that can be used?
A: If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.
