Smart Digital Electric Meter

Project Title

Smart Digital Electric Meter

Project Area of Specialization Internet of ThingsProject Summary

Our project is based on internet of things which includes the replacement of existing electric meters with our new and Smart Digital Electric Meter that allows for elimination of misreads and rereads by lineman, accurate meter reading and consumption, user can get to know the accurate usage of electricity, that will help to reduce bill cost. Remote turn off and on capabilities are also gained and provide operational efficiencies and improved customer service. Electric companies can create a geographical mapping of city electric meters with consumption chart of different areas.

Project Objectives

The goal of this projectis that above we discussed problem statements like customer having problemsinbilling and consumption of electricity because these things are manually in this time but ouraim is thattomake things automatic in our project like e-billing, notified consumers along with the company.

Project Implementation Method

Firstly, electricity is passes from our device. Our device has an Arduino unit installed in it with the internetshield and a small memory unit which stores recording of the consumption of the electricity. Internetshieldthen transfer it to our web server, with shared database for the android application. All of the information isbeing displayed in our web portal while limited information to the user.Resultant will eliminates misreadsand extra units charges.

Benefits of the Project

Following are the advantages of the meter.

•From our meter misreading error will be eliminated

•Reduces third party meter reading

•Removes Theft of Electricity

•Power Saving

•Removes meter Tampering

•User will be updated withtheir consumption

•High Power Consumption with area details

Technical Details of Final Deliverable

We try to implement our project in to real. As our project have three phases which is smart meter, web portal and an android mobile application Firstly, moving to the smart meter. It consists of many electronics sensors. Current, Voltage, SD Card, LCD, GPS and GSM module. All of these components combine to make smart meter. A circuit is designed on which all of these components are embedded. Arduino works as a CPU for this circuit, take the values received from the sensors send to the server after doing some calculations. It can also display these data to the LCD. Receiving the values from the meter are stored in web database. From the web portal company can aware of the user’s consumption and overloading. User also can login to view its detailed data on web portal. An android application is provided to the user where he can see its consumption, voltages units consumed and the estimated end month bill.

Arduino We are doing multitasking in Arduino with the help of millis( ) function. Each function performs in a loop in Arduino for example, if we want to send Data from GSM, and GSM takes times in sending data which led the device stuck in that piece of code for a while. To overcome this and Arduino keep on recording data we use multitasking in Arduino. Units Calculations units = kwH watt = V * I V = Volt I = current (Ampere) kwH = kwH + (watt / 1000 / 3600) Initially kwH is zero, so zero is added with the current units. After some time, previous units are added in consumed units We use Soft Serial Library in Arduino which allow serial communication on other digital pins of Arduino. AT Command are used to control GSM. Every command line is start with “AT” or “at”. For Example, ATA Answer Command ATD Dial Command ATH Hang Up Call EmonLib (e monitor library) it is used in Arduino to monitor AC voltages and Current. SD FAT library used in Arduino for SD Card. SD Card is used in our project as a backup database. If there is any power failure, meter start saving reading in the memory card. Liquid Crystal library used in Arduino for LCD. And I2C library is used for I2C Circuit which convert 16 pins of LCD to 4 pins.
