Industrial Worker Safety Device with Proactive Gas Leak and Fire Protection System

Gas leaks and fires present dangers that require detection and decisive action to protect lives and property. This paper specifically proposes cutting-edge sensor technologies with intelligent threshold algorithms and real-time communication capabilities to enhance the safety and well-being of industrial workers by reducing the risk of accidents and injuries, which addresses Sustainable Development Goal (SDG) 3 (good health and well-being). It includes MQ5 and MQ135 gas sensors, a DHT11 temperature sensor, and an IR flame sensor to provide monitoring. The real-time data from the gas sensors is carefully analyzed to trigger alerts at two threshold levels directly linked to gas concentrations, ensuring warnings in case of any risks. If the second threshold is exceeded, indicating the presence of gas, the device activates a safety protocol. An exhaust fan swiftly dissipates any accumulated gas, while a servo motor promptly shuts off the gas supply, effectively preventing any escalation of the situation. An integrated Wi-Fi module will enable communication and notifications through a dedicated smartphone app or web interface to enhance functionality, which enables remote device control and real-time access to sensor data for users. This combination of sensor technologies, intelligent algorithms, and remote accessibility showcases how technology-driven solutions can significantly enhance safety measures.
