Fire accidents pose significant risks to life and property, often due to delayed detection. Traditional single-sensor alarms lack accuracy and reliability. This presentation introduces an innovative multisensor fire alarm system using Arduino UNO, combining smoke and flame detection for early and accurate fire warnings. The system provides immediate audio-visual alerts, making it ideal for homes, schools, and industries. Its low-cost design and modular structure allow for future enhancements, demonstrating how embedded technology can enhance safety.
Problem Statement
Traditional fire alarms rely on single sensors, leading to false alarms or delayed detection
Many fire incidents escalate due to inadequate early warning systems
Existing solutions lack accuracy and reliability in diverse environments
There is a need for a cost-effective, accurate, and responsive fire detection system
Objectives
Design a multisensor fire alarm system using Arduino UNO
Integrate smoke and flame sensors for dual detection
Ensure immediate audio-visual alerts via buzzer and LED
Develop a low-cost, easy-to-assemble prototype
Enhance accuracy and reduce false alarms through threshold monitoring
System Components
