Design and Implementation of an Arduino-Based Home Security System with Fire, Gas and Intrusion Detection
Ms. Prajota D. Shrimanwar
Home security has become a major concern due to increasing incidents of fire hazards, gas leakage, and unauthorized intrusions. Traditional security systems are often expensive and limited to a single function. This paper presents the design and implementation of a low-cost Arduino-based home security system capable of detecting fire, gas leakage, and human intrusion using a flame sensor, MQ-2 gas sensor, and PIR motion sensor. The system provides real-time alerts through a buzzer and a 16×2 LCD display. Experimental results show fast response time, reliable performance, and effective hazard detection. The proposed system is economical, easy to implement, and suitable for homes, offices, and small commercial environments.
