Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

[Andy] demonstrates building an ultrasonic anemometer using a cheap after-market parking distance sensor kit and an Arduino. Demo video after the break. Aside from the price, these kits have the ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same ... See the tried-and-true adapter circuit diagram below. A simple Arduino Sketch for obtaining the ...
