Arduino based Smart System for Control and Effective Billing

As the technology is advancing in each and every field, it also advanced in making houses smarter where one can control the appliance remotely. Here the word smart also helps in generating the bill(displays on Bluetooth app) in a way of reducing the human effort in calculating all the necessary parameters. But not every person knows how electricity works and how the bill is generated. So, the main objective of this project is to let every user know how the consumption of each appliance effect the bill. This project also helps the user to control the home appliance remotely using a smart phone(using same Bluetooth app). So, the application designed in this project will full fill the need. PZEM004T is used to get the values of voltage and current which will be further used in the generation of bill. The values from the sensors are communicated to the Arduino and the bill is generated. Here, a Bluetooth module is used which acts as a medium and helps the data gets transmitted. All the necessary controls of the appliance and its energy consumption will be present in an Android Application.
