This project provides a reliable early-warning system for smoke and combustible gas detection, suitable for home or industrial safety monitoring.
Electrochemical Gas Sensing: Interfaces with the MQ-2 sensor, which captures analog voltage changes proportional to gas concentrations (LPG, Smoke, CO). The Arduino's ADC converts this to a digital value for threshold comparison.
Dual-Action Alarm Hub: When the PPM level exceeds the safety setpoint, the Arduino simultaneously triggers a high-decibel piezo siren and flashes a primary alert LED.
Calibration Logic
Baseline Normalization: Includes a startup calibration routine that samples atmospheric conditions for 60 seconds to ensure accurate reading offsets in varying environments.
