The “object detection and alerting system in car using IoT” for enhanced safety project introduces a novel approach to bolster safety by seamlessly integrating Internet of Things (IoT) technology into object detection and alerting systems. This project addresses the critical need for proactive detection of objects and obstacles in various environments, enhancing user awareness and minimizing potential hazards. Nowadays, there are many safety and security systems in the car such as airbags, anti-lock systems, etc. Whenever a hand is placed on the car door panel or frame and the car door is closed unnotified or unchecked or accidentally or in another case like whenever the children are playing and place their hand on the car door panel accidentally while the car door is closing, this causes injuries. So, we came up with a system “object detection on the car door panel and alerting system” in a car which detects the obstacle while closing the car door and prevents these types of injuries or accidents from occurring. The project's design embraces the principles of IoT scalability and adaptability. The modular architecture allows for seamless expansion of the network to cover larger areas or new environments. Additionally, it can integrate with existing IoT ecosystems, smart homes, or industrial setups, amplifying its usability across diverse applications.
