In this case, Arduino distance sensors use sound to work out how distant objects are. Ultrasonic waves that humans can't hear are emitted by the sensor, and the time the sound takes to bounce back ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module ... The set-up process is very simple, and best understood by referring the wiring diagram.

Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

There are at least 20 different ones available in the Arduino Store, but which among them is the best board for beginners ... like a piano made out of ultrasonic sensors, a tissue box that ...

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 ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...
