Biometric Authentication and Risk Alert System for Chemical Laboratories

When chemical laboratories are exposed to harmful gases like toluene, they pose significant safety issues, leading to severe health problems. Inadequate gas detection systems and unauthorized access cause serious safety risks. This project aims to improve safety and security of chemical laboratories by combining biometric authentication with real-time gas detection. Biometric authentication system has been widely used in the industries for safety while gas detection system is important for industrial safety. However, both these systems work independently and thus, leaves the gap in providing complete safety solutions. The system uses microcontrollers, fingerprint module for biometric authentication and gas detection sensors for gas detection. Wirelessly, real-time data and risk warnings are transmitted. A model was built consisting of fingerprint authentication system and gas detection system. Entry is controlled by fingerprint authentication system, while the gas detection system inside the lab triggers alarms and locks door if toluene level exceeds 200 ppm.
