Drowsiness is one of the major factors for road accidents. According to the recent survey it accounts for nearly 40% of Road Accidents due to drivers dozing off. For preventing these kind of accident from occurring and to alert the drivers there are many exiting systems which are designed using several methodologies. Most of these Systems have camera as their input parameters. This Paper is an example for IOT based Drowsiness Detection system using IR sensor. Here IR based eye sensor is used to detect the eye blink of the drivers. Arduino nano is used for drowsy devices detection and other eye blink related detections.
