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 project demonstrates how to use an ESP32 microcontroller to measure the distance to an object using an ultrasonic sensor and display the measured distance on a 16x2 LCD. The project is designed ...

The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...

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 ...

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 ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...
