Iot based smart prepaid energy meter

Project Title

Iot based smart prepaid energy meter

Project Area of Specialization Internet of ThingsProject Summary

The aim of the project is to minimize the queue at the electricity billing counters and to restrict the usage of electricity automatically, if the bill is not paid. The work system adopts a totally new concept of Prepaid Electricity. The GSM technology is used so that the consumer would receive messages about the consumption of power (in watts) and if it reaches the minimum amount, it would automatically alert the consumer to recharge. The users can view their current energy meter reading through mobile they can also monitor their energy meter online. By using this system, the users will be aware of the electricity uses in his/her home. With slight modifications to the system, it can be used by corporate companies to monitor their power consumption and help them reduced the power wastage to a greater scale.

Project Objectives

 the advancement of technology and dependencies over the 
electrical appliances increases, the usage and requirement of 
electricity is also increases rapidly. Project is a smart energy 
prepaid meter based on Internet of Things. This smart meter
 will be helpful in generating the real-time data of the 
electricity usage. Users will be able to see their daily usage 
from a web app with the help of their unique identification 
number and password provided to them at the time of 
installation of this device. The main aim of this project is to 
make a novel system which will help in reducing the usage of 
electricity and bring transparency between the electricity 
providers and the customers. This meter needs to be recharged 
similar to a mobile phone, 

Project Implementation Method

We have use esp-wroom 32 as our controller which is integrated with gsm modem, voltage sensor and current sensor. Gsm modem is used for recharging of units as like we recharge our sim. The data is then read by esp-wroom 32 and it is send to the firebase based server. A mobile application is integrated with server and we can also moniter all the parameters on mobile application.

Benefits of the Project

It is highly accurate as the whole idea of reading the units and then billing manually or any other mean is eliminated

Consumer can't escape from paying the electricity bill

On the consumer front, the tedious task of paying the bill amd waiting anxiously for the bill is eliminated

Technical Details of Final Deliverable

Wapda 220 v supply coming from normal energy meter is then goes through a 220v-12v step down transformer. Then we use bridge configuration of diodes for conversion of Ac to Dc. And some filter capacitors. This 12v dc is then converted into 5v fotrelays operations and 3.3v for esp-wroom 32 using 2 regulators. Gsm modem received message and our controller reads these instructions for recharging of system. Similarly our controller send message through gsm when units getting low or end. and when all units get consumed electricity automatically cutts off. All the parameters are send after some time interval to the server and our application continuesly reads server and update data on it self.

Consumer can also turn ON  or OFF the rooms electricity from any where through application.
