HeatGuard - Arduino Rate-of-Rise Heat Detection System

About this project

Build intelligent rate-of-rise heat detection system using Arduino Uno with DHT22 temperature sensor for early fire warning. Monitor temperature rise rate to detect fires before fixed-temperature thresholds are reached, implement dual-threshold detection (rate-of-rise + fixed temperature), display real-time temperature trends on LCD, trigger alarm on rapid temperature increase (>8°C/minute per NFPA standards), log temperature history for fire investigation. Perfect for areas with high ambient temperatures, enclosed spaces, industrial environments, and clean rooms where smoke detectors are unsuitable.
