Human security from death defying gases using an intelligent sensor system

• The paper claims novelty for being able to detect the hazardous gases like methane thereby protecting the human community from death.
• Using GSM giving alert signal is common but the approach of detecting the presence of gases and its level are very precise and clearly stated.
• The states of art in writing the manuscript using latest papers are relevant and the ideas of implementation are exemplary.
• The conclusion and further progress in this research are obvious and more helpful for the society in handling hazardous gases.

Hazardous gas contamination causes threat to human life. In many developing countries, the sewers are still cleaned by unskilled laborers. Situations may arise where harmful gases may get emitted via sewage and can potentially endanger life. Furthermore, in coal mining, there is a possibility of hitting a source of natural gas which cannot be determined unless or until a sensor is utilized. To prevent such hazardous situations, this new gas detection system detects those types of gases, analyzes them for us and provides essential details about it.Our system is designed to track the presence of hazardous gases, identify the safety limit and calculate the level in that situation, thereby preventing hazards to human life. It allows detection of carbon monoxide and methane at the given time, along with their accurate concentration values in ppm. The system also provides a threat detection alert so that the persons immediately evacuate that area, thereby preventing any possible dangers. The alert messages are broadcasted using GSM technology and hence, can be used to notify other rescue workers about the potential hazard the worker is facing at the moment.
