IoT based Vehicle Over-Speed Detection and Accident Avoidance System

Vehicle over-speed detection and accident-avoidance system is an Internet of Things (IoT) based system which collects data via sensors such as ultrasonic sensors and alerts the driver. The sensor is mounted upon a microcontroller i.e. Arduino which is responsible for the sensors to work. This system consists of an Ultrasonic Sensor, Arduino UNO, Potentiometer, CAN Controller, DC Motor, GSM, LCD display and a buzzer. The ultrasonic sensor detects the object/vehicle ahead of the vehicle and sends the data to Arduino UNO, if a particular vehicle is in close proximity to the front vehicle, the proposed system automatically controls the vehicle speed. This system also consists of an over-speed detection, which detects the speed and alerts the driver if the vehicle reaches a specific speed limit. Also, in the proposed system in case if driver overspeeds, an SMS alert would be sent to cab company or car rental agency concerned person's cellphone.
