Vehicle anti-occupancy detection device

With the rapid advancement of the times and technology, the updating of automobiles is very swift. The popularization of automobiles brings convenience to life, but also numerous problems. Safety accidents caused by being mistakenly left in the car have become a significant proportion of non-traffic accident deaths inside vehicles. This paper focuses on a vehicle detection device aimed at preventing accidental human occupancy. By utilizing the central control function of a microcontroller, it achieves data collection, display, judgment, and corresponding operation functions of various devices. It uses human and sound sensors to detect the presence of humans in the vehicle, preventing dangerous situations such as children or the elderly being trapped inside.
