Smart Fire Alert
IoT safety system combining ESP32 smoke and flame sensors with instant remote alerts and emergency workflows.
The Problem
Traditional fire alarms only sound locally, failing to notify remote property owners or emergency contacts when a building is unattended.
The Solution
ESP32-powered sensor fusion system that detects smoke and flame signatures simultaneously, triggering immediate cloud alerts and dashboard notifications.
Development
Multi-sensor threshold logic written in C++ for ESP32 to reduce false alarms while maintaining rapid response times.
Challenges
Calibrating optical smoke and infrared flame sensor thresholds to avoid false positives from dust or sunlight.
Outcome
Working hardware prototype streaming live alerts to remote dashboard.
Lessons
In safety-critical IoT systems, false-positive filtering is just as critical as detection speed.
