NodeMCU Based Automatic Electricity Meter Reading Using IOT

The use of electricity is increasing continuously day by day in our country. With the rapid development in technologies and wireless communication in industries, the advancement in technology changes the people life, decrease their manual efforts & also rises the economic growth of the country. Before manual reading technique was used everywhere, for that worker have to work hard. A person from the Electricity office came into our house, note the reading manually, calculate or estimate the bill consumed by a consumer & send it to them. In each area, each house worker has to go to note the reading & if the consumer is not present then he has to again revisit to take the reading, so it will be a difficult task for them to manage & calculate the bill. While doing all these tasks, sometimes they do mistakes in taking a reading or calculating the bill, sometimes misplace the bill like one consumer bill goes to another, due to that it is not possible to get an accurate bill or consumer obtaining extra amount as compared to their consumption unit. All the issues can be resolved with the help of only IoT, it is used to give accurate meter reading using the internet without human intervention, used to reduce the power consumption & used inadequate amount, also protect the system from theft if someone tries to misuse the electricity or if the user did not paid the given bill whatever they consumed at a given time, then by using relay host will cut the supply automatically from the remote area. In this project, a normal meter is converted to a smart meter reading with the help of NodeMCU & IoT. The consumer can manage the power consumption as per need as the consumer can see the daily consumption of power. If any theft occurs then in meter, it shows theft or bill is not paid on time by consumer then message will send to the consumers through NodeMCU & automatically supply will cut using a relay.
