This project enables real-time distance measurement using an ultrasonic sensor (HC-SR04) and displays the measured distance on a webpage. The ESP32 microcontroller reads the data from the ultrasonic ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

This project demonstrates how to use an HC-SR04 ultrasonic sensor with Arduino and ESP32 to measure distances accurately and integrate them into DIY electronics or IoT projects. The ultrasonic sensor ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...
