This project presents an eco-friendly method of generating electricity from biodegradable kitchen waste, such as vegetable and fruit waste, while incorporating IoT-based monitoring for real-time performance analysis. The system helps address waste management and renewable energy generation by converting organic waste into useful electrical energy. The waste materials are crushed into a slurry and separated into solid and liquid components. The liquid waste, rich in organic acids, acts as an electrolyte in a bio-electrochemical setup. Using zinc and copper electrodes, a chemical reaction generates DC voltage, which is stored in a rechargeable battery and used to power LEDs and other low-voltage loads. To enhance the system, a voltage sensor continuously monitors the generated output. A PIC microcontroller processes the sensor data and transmits it to the ThingSpeak cloud platform through an ESP8266 Wi-Fi module. This enables real-time monitoring, remote access, data logging, and performance analysis of the energy generation process. The proposed system demonstrates how biodegradable waste can be converted into a sustainable energy source while integrating modern IoT technology for smart monitoring. It is suitable for science exhibitions, educational projects, renewable energy research, and low-cost green energy applications.
