LOW POWER CONSUMPTION FOR O2 AND CO GASES MEASURING BASED IoT SYSTEM AT CONFINED SPACE AREA

Abstract

Confined spaces such as tanks pose significant risks to workers due to limited airflow and hazardous gas accumulation. Occupational Safety and Health Administration OSHA in confined space requirement mentioned the oxygen (O₂) concentration for confined spaces is typically between 19.5% and 23.5%, while carbon monoxide (CO) levels should remain below 5 ppm to ensure a safe working environment. The absence of real-time monitoring increases the potential for accidents and threats to worker safety based on. With real-time monitoring, the standby person (SP) can stay more alert to gas concentrations in the confined space and helping to respond quickly to any dangerous changes. This study aims to develop a portable device for low power consumption gas measurement system for O₂ and CO using Internet of Things (PCGIoT) technology that providing remote monitoring capabilities to ensure safety. The system's performance was analysed of its power consumption and demonstrating its ability to deliver accurate, real-time data. The results demonstrate the system's ability to effectively monitor gas levels in confined spaces to ensuring safety by detecting changes in carbon monoxide (CO) and oxygen (O₂) concentrations. The findings demonstrate that by detecting variations in CO and O₂ concentrations, the system can efficiently monitor gas levels in tight places to guarantee safety. O₂ concentrations often fall as CO levels rise. This has a track record of using the Internet of Things. Additionally, because PCGIoT devices use very little current, batteries last for around 40 hours, making it a good option for continuous monitoring while reducing exposure to hazardous gas levels and all the hazards that come with it. With data accessible remotely, the device provides the most practical way to continually monitor gas safety for workers in restricted spaces.
