Industrial internet of things solution for monitoring ammonia and carbon monoxide in industrial staging areas.

Hazardous gas leaks are currently leading the cause of industrial accidents. Human activities in industrial areas, especially when conducting inspection using a Gas Cylinder containing CO and NH3 which are invisible and have a negative impact on health with Permissible Exposure Limit 50 ppm. Due to the risks of gas leakage, some solution to minimize the risk to human health is needed. There are still many conventional gas leak detections which no regular and real-time monitoring. To overcome this, a CO & NH3 gas monitoring and detection system were designed in the staging area which can automatically be monitored remotely based on the Internet of Things (IoT). The sensors used are MQ-7 to measure CO gas concentration and MQ-135 sensors to measure NH3 gas concentration. Gas concentration status will be monitored via the web in real-time and notification of each gas status will be sent via Telegram. Once the gas concentration is exceeding the safe limit, it will turn the DC fan on. Buzzer and LED are used as indicators of gas condition status in the room. Are better for continuing this study also monitor other parameters like room temperature for making more safer environment for workers. [ABSTRACT FROM AUTHOR]
