IoT-Based Prepaid Energy Meter Using Nodemcu and Arduino

Abstract

The conventional energy meter, which we use in our households to measure energy consumption, is an offline device, so it has to be monitored manually. As the country’s population increases, it is becoming most difficult to take the reading of energy meter from each home. As number of houses increases, it may be possible but it take lot of manpower. The customers are unaware of electricity usage, which results in huge bills. Electricity theft is common in some rural areas which results in both operational and economic loss. To avoid these problems, our Prepaid Energy Meter plays a key role. This proposed project makes consumers happy because they can monitor their usage through the internet. In this proposed model, an automated system by NodeMCU and Arduino is implemented. SMS is sent to recharge the meter. Since IoT is being used, it can monitor the status of the energy through the Internet. The recharge can also be done through the Internet. If there is an insufficient balance, then the power supply connection is simply disconnected from the house. The automated alerts are also sent in the form of messages to the end user's mobile phone according to the balance present in the system. With this proposal labor requirements, electricity theft, and billing errors are reduced.
