ABSTRACT
Internet of things (IoT) is capable of transferring information efficiently regarding wireless energy consumption, and at the same time, it is capable of detecting the usage of electricity. With the current technology, taking readings requires us to go to the meter reading room. Consequently, keeping tabs on our energy usage is a lot of work. A sophisticated digital gadget called a smart energy meter was created to take the place of the conventional electricity meter. By enabling us to manage and lower our energy use, installing a smart meter will help us do away with projected costs. It has the ability to acquire data remotely and submit meter readings to energy providers. The aim of the present work is the measurement of electricity consumption in home appliances. The circuit in the current work is interfaced with the ESP32 Wi-Fi module to examine all the requirements for an electrical energy meter using the SCT-013 current sensor and ZMPT101B voltage sensor. The system can send the data to the Blynk server from all over the world with original hardware circuitry on a permanent PCB. On the Blynk application dashboard, the voltage, current, power, and overall unit utilized are displayed in kWh. Lastly, we do an energy audit, which provides detailed information about total electrical energy consumption by the utilities in the central library, NITTTR, Sector-26, Chandigarh, and recommends necessary energy conservation opportunities (ECOs) for the conservation of energy. Further, we conclude with necessary energy conservation recommendations using our proposed system.
