Smoke Detector System
Arduino micro-controller hazardous gas and smoke monitor with audio-visual alarms
How It Connects
An embedded IoT safety system powered by an Arduino microcontroller and MQ-series analog gas sensors. Continuously samples PPM thresholds for carbon monoxide and combustible smoke, triggering buzzer sirens, status LEDs, and relay shutoffs when dangerous concentrations are breached.

How It Works
Continuous ADC Sampling
Samples analog voltage from MQ-2 sensor every 200 milliseconds.
Threshold Breach Alert
Triggers high-decibel piezo buzzer and flashing red LED indicator.
