IoT-Based Real-Time Carbon Monoxide Mitigation for MSME Indoor Environments

This study aims to develop an IoT-based real-time carbon monoxide mitigation system for monitoring and controlling CO levels in MSME indoor environments.The methods used in this study include problem analysis, and product design, followed by three stages of experiments in which the CO concentration is systematically increased from 50 ppm to above 200 ppm for system response testing.The subjects of this study were MSMEs that use fossil fuel equipment in their daily operations.The results show that the system effectively detects increased CO levels and responds appropriately.At a CO concentration of 58 PPM, Fan 1 is activated, while at a CO concentration of 105 PPM, Fan 1 and Fan 2 are activated with low-intensity buzzer alarms.When the CO concentration exceeds 200 PPM, the system triggers maximum safety action, activating both fans, a high-intensity buzzer, and a red emergency light.In addition, real-time notifications are sent to mobile devices, ensuring alertness and rapid response.The findings of this study indicate that the use of IoT technology in managing workplace safety can significantly increase the speed and effectiveness of responses to CO gas threats, potentially reducing the risks faced by workers in MSME workplaces.
