This time a took a look at (and inside) an ultrasonic parking sensor. It looks like a traffic light and it should prevent you from hitting the wall of your garage :). It uses an ultrasonic impulse that's being reflected from your car to detect its distance. I reverse engineer its schematic and try to explain how does it work.
