This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

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 ...

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 ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

Thankfully, there's an Arduino project to help you out with that — this gesture-controlled system for VLC. It features two ultrasonic sensors mounted on your computer's display monitor (much ...

DIY blog Mad Science has put together a tutorial to roll your own sensor system with an Arduino. The build is incredibly simple and you only need a ping sonic range finder, Arduino, a buzzer ...

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 ...

If this sounds like rocket science to you, well, it’s not, as someone has built such a device using a cheap Arduino board. Paired with two sonic sensors mounted on the garage ceiling ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.
