Thermo-Powered IoT Fire Detector: A Self-Sustained Smart Safety System

Fire detection systems play a critical role in ensuring safety, yet their reliance on external power sources limits their deployment in remote or energy-constrained environments. This study presents a novel system that transforms waste heat into electrical energy for fire detection. Using the See beck effect, the system harvests heat from power plant chimneys, vehicle exhausts, and direct fire sources to power a microcontroller, heat sensors, an OLED display, and an IoT module. The sensors monitor temperature fluctuations, identifying potential fire hazards. Data is displayed locally and sent to the cloud for remote monitoring and timely alerts. By repurposing waste heat, the system minimizes environmental impact, reduces energy waste, and eliminates dependence on external power sources. This approach combines energy recovery with smart safety features, offering a sustainable and cost-effective solution for fire detection while addressing global energy challenges.
