During hot summer months, tragic accidents can occur when children are left behind in school buses. To stop this from happening, we decided to take action!

We are a team of four students from Chung-Ang University Affiliated High School, working together under the name “중고이노(CAUINO)”. Combining creativity and technology, we aim to build a real-time passenger counting system that ensures no child is forgotten inside the bus.

Our system uses Arduino-based sensors to count children as they board and exit the bus. If the numbers don’t match, the system raises an alert to the driver and school staff, preventing potential accidents before they happen.
