Abstract: Leaking Liquefied Petroleum Gas (LPG) and other flammable gases into residential, industrial, and business areas can be very dangerous. There is a chance of fire, explosion, and toxic exposure. Existing gas detectors that work on their own don't have the ability to be monitored from afar, to expand the network, or to be activated automatically. The design, implementation, and testing of a Wireless Sensor Network (WSN)-based smart gas detection system that can continuously track hydrogen, smoke, LPG, methane (CH4), and carbon monoxide (CO) are all shown in this paper. The system uses MQ-series electrochemical sensors that are linked to Arduino microcontrollers through a tree-shaped ZigBee mesh network. When safety limits are crossed, the system sounds and lights up alarms at the same time, turns on an exhaust fan and shuts off the gas valve, sends SMS alerts through a GSM module, and posts real-time data to the ThingSpeak IoT cloud platform. An experiment with three sensor nodes shows that the system can reliably identify objects 97.3% of the time, respond in 3.8 seconds on average, and communicate wirelessly 99.1% of the time at up to 150 meters away. The proposed system is much more accurate, has faster reaction times, and covers more operations than current systems. |
