Development of Heateye: A Smart Application an Arduino-Based Heat Detector Device for Household Appliances

In the Philippines, household appliances are often used for extended periods, which may lead to overheating, electrical hazards, and, eventually, fire-related incidents. Existing temperature monitoring systems typically offer only basic alert mechanisms, limiting their effectiveness in preventing accidents and ensuring appliance safety. This study focuses on the development of HeatEye, an Arduino-based heat detector integrated with a mobile application for real-time temperature monitoring and remote appliance control. The system uses an Arduino Uno, an LM35 temperature sensor, an HC-05 Bluetooth module, and a relay module to detect abnormal heat levels and automatically respond when the temperature exceeds the programmed threshold. The mobile application provides live temperature updates, overheating notifications, ON/OFF remote operation, timer automation, and historical temperature logs with graphical visualization.
