Is it possible to create a cheap and effective proximity sensor for a vehicle using an Arduino and distance sensor? This proposed system could act as a collision prevention system by sounding an alarm if the distance between an object and a vehicle decreases to a dangerous level.

In 2021, frontal impacts accounted for 18 driver deaths per million registered passenger vehicles in the US [1]. However, an onboard digital warning system could have easily prevented many of these collisions. Such a system can give a driver precious seconds to take action and avoid a crash. This is why most new vehicles have a built-in collision prevention system that uses radar to sound an alarm if it gets too close to whatever is in front of them [2]. These systems have been proven to reduce crashes and injuries from forward collisions by about 40% [3]. Unfortunately, older vehicles do not have this warning mechanism built in. To fix this problem, we propose an affordable collision prevention system with an Arduino Uno, an ultrasonic sensor, and a piezo buzzer that works similarly to a newer car.
