Design of Urban Bus Alarm System (UBAS)

The main goal of the system developed in this paper is to reduce fatalities caused by children being forgotten in buses. The study is particularly interested in designing and developing an alarm system that detects sitting and moving people inside a turned-off bus using affordable electronic components such as Arduino, several sensors such as motion, infrared, and pressure sensors, and a camera to livestream the bus's status via WiFi to any smart device, where the status of sensors and the number of remaining passengers can be viewed via the Blynk APP. The designed three level alarm system shows its applicability and can be plugged into any conventional bus to create an alarm system suitable for urbanized buses and called Urban Bus Alarm System (UBAS).
