The generated voltage is continuously monitored using a voltage sensor and regulated through a charging circuit to safely charge a battery. The stored energy is supplied to loads such as a bulb through an inverter and to six exhaust fans that are connected to the incinerator to maintain proper airflow and remove flue gases.

A heater, controlled through a solid-state relay (SSR), is connected to the incinerator to support and stabilize the combustion process when required. Additionally, a vibration motor is attached to the incinerator to remove accumulated dust and ash particles, ensuring efficient heat transfer to the Peltier plates and improving overall system performance.

A regulated power supply (230V AC input) provides power to the control circuitry and supporting components. The PIC microcontroller acts as the central control unit, managing heater operation, monitoring voltage levels, controlling system components, and displaying key parameters on an LCD display.

This system demonstrates an effective method of converting waste heat from incineration into usable electrical energy while reducing waste volume and supporting small-scale power generation applications.
