Smart detection system with real-time notifications for smoke and gas

Gas leakage is one of the hazards that causes significant damage. Some of the risks include safety hazards: gas leaks can lead to explosions, fires, and pose significant risks to life and property. Economic losses: gas leaks can result in financial losses due to wasted resources. Uncontrolled gas leaks can lead to higher utility bills for consumers and loss of revenue for gas companies. Fire accidents are like disasters which causes enormous damage to both living and non- living things. The damage might be small or large, but there is always some sort of loss. Ionization or a photoelectric sensor can both be used to detect smoke. Carbon dioxide can be sensed to identify fire without smoke. Carbon monoxide detection allows for the detection of incomplete burning. When taking into account primarily residences, shops, and small business stores, no one can predict when a fire or smoke will occur. Therefore, a device for continuous, low-cost monitoring is needed. Regarding this, a system has been designed that detects smoke, combustible gases, or fire and sends out an alert to warn those nearby, as well as sending warning notifications to store or house owners. WhatsApp, the most widely used app worldwide, serves as a platform for receiving notifications. The results show that the system was effective in repeatedly alerting and sending notifications whenever smoke or any combustible gas occurred and stops sending notifications when gas or smoke stops
