About this project
Build an addressable multi-zone fire detection system using ESP32 and four MQ-135 air quality sensors monitoring separate building zones. The system features a real-time web dashboard accessible via WiFi, displaying smoke concentration levels, zone-specific alarm status, and event logs. SD card logging provides tamper-proof audit trail for fire marshal inspections. NFPA 72 compliant zone annunciation identifies exact fire location, enabling faster emergency response compared to conventional single-point detectors.
