An IR sensor is used to detect the presence of a person on the seat. Once detection is confirmed, a servo-motor–based automatic seat belt mechanism secures the passenger safely. For mobility assistance, a servo controller and ROBO switch are employed to operate a movable chair that lifts, rotates, and positions PHC passengers comfortably into the bus. The bus movement is controlled via an HC-05 Bluetooth module, enabling remote operation through an Android mobile application, which ensures safer and easier handling by the caretaker or driver.

A fire sensor is incorporated to detect fire or high-temperature conditions inside the bus. On detection, a buzzer alert is triggered to warn passengers and operators immediately. Power to the entire system is regulated using an LM2596 voltage regulator, ensuring stable operation from the battery supply. Additionally, an L298N motor driver controls the DC motor responsible for bus movement.

Overall, the system provides automatic safety, enhanced accessibility, remote control capability, and early fire detection, making public transport more inclusive, reliable, and secure for physically challenged and elderly passengers.
