The aim of this project is to design and implement a Bill Estimation system based on IoT with an objective to provide the user with real-time electricity consumption and electricity bill estimation. The proposed system uses an Arduino Uno module integrated with ESP32 as opposed to the earlier model which used NodeMCU. Arduino Uno is used in order to control the appliances more efficiently and to provide accurate data to the user. To precisely measure the current it uses an array of multiple sensors based on which the appliances are controlled thus electricity is also reduced. Our system can be implemented in two ways, a decentralized version where each electrical appliance or gadget provides input data to the Arduino Uno and a centralized version that has loads coming from different rooms containing electrical appliances as an input to the Arduino Uno. Therefore our project has the potential to be used in industries as well as commercially by the public.
