The Automatic Smart Bus Stop Sunshade System is designed to provide improved protection and comfort for passengers waiting at bus stops during different weather conditions. Conventional bus shelters provide only fixed coverage and may not effectively protect passengers from changing sunlight directions or rainfall. The proposed system uses an intelligent motorized sunshade mechanism that automatically adjusts its position according to environmental conditions. The system uses Light Dependent Resistor (LDR) sensors to detect the direction and intensity of sunlight. Based on the sensor readings, the microcontroller controls a servo motor to rotate or adjust the sunshade towards the appropriate direction, providing maximum protection from direct sunlight. A rain sensor is also incorporated to detect rainfall and automatically adjust or expand the sunshade to provide better coverage for passengers. The microcontroller acts as the main controlling unit and continuously monitors the inputs from the LDR and rain sensors. According to the programmed conditions, it controls the motorized mechanism automatically without requiring human intervention. The system is programmed using Embedded C language. This proposed smart bus stop system improves passenger comfort, provides protection from sunlight and rain, and offers an efficient and automated solution for modern public transportation infrastructure.
