Circuit Diagram

Connected to the Arduino UNO R4 is an ESP32, which interfaces with a 7-inch HMI display to provide users with a comprehensive and intuitive view of their energy consumption. The display presents real-time information on AC voltage, wattage, and power factor, all of which are measured continuously by voltage and current sensors. This setup enables users to monitor their energy usage effectively and make informed decisions based on current data.

The system also integrates renewable energy sources, including solar panels and a windmill demo featuring an N20 motor. The solar panels are equipped with sensors to monitor light intensity and voltage, while the SMMPT solar charger efficiently manages energy storage by charging batteries from the solar power collected. This combination of renewable sources not only supports sustainability but also enhances energy efficiency.

For user interaction and control, the system features a 4-channel relay module, allowing precise management of various AC applications. Additionally, the VC-02 offline voice recognition module provides voice-command functionality, enabling users to control the system with ease and convenience. Integration with Blynk facilitates remote monitoring and control, giving users the ability to access and manage their energy system from anywhere in the world.

Overall, the Arduino UNO R4 is pivotal in orchestrating the system's diverse components, ensuring a cohesive and efficient energy management solution. Its ability to integrate real-time data display, renewable energy sources, advanced control features, and remote monitoring capabilities underscores its role as the central element in creating a smarter, more sustainable home.
