Smart Radiator Monitoring Vehicle System for Automotive Engine Safety and Efficiency

Vehicle engine overheating is a widespread issue that often goes unnoticed until significant damage has already occurred. This problem is commonly caused by radiator-related faults such as coolant leaks, clogged passages, or malfunctioning thermostats. Many existing systems fail to provide early and accurate warnings, putting vehicle performance and safety at risk. The study developed a Smart Radiator Monitoring Vehicle System that offers real-time temperature tracking and immediate alerts to help vehicle owners respond before serious issues arise. The system uses a DS18B20 digital temperature sensor connected to an Arduino Uno microcontroller, which continuously monitors engine coolant temperature. When readings exceed safe levels, the system activates visual and auditory alerts and displays real-time data on an LCD screen. The development followed the ADDIE framework Analysis, Design, Development, Implementation, and Evaluation ensuring that each stage addressed real user needs and technical challenges. We tested it on Ford Ranger diesel-powered vehicles; the system demonstrated high reliability, accuracy, and usability in identifying overheating conditions. This solution provides a practical, affordable, and easy-to-install way to enhance engine safety and efficiency. The study also supports the growing integration of IoT and embedded systems in modern automotive applications.
