Arduino code for detecting basic hand gestures using HC-SR04 ultrasonic distance sensor array. This code utilizes three HC-SR04 ultrasonic distance sensor modules placed linearly with a fixed distance ...

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 ...

If you are an electronics engineer or a beginner and want to build an obstacle avoidance robot, you need to first learn how an obstacle avoidance system works! which makes this project of ours super ...

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 ...

Abstract: We developed a new 3D image sensor consisting of an FPGA board, an ultrasonic transmitter, an array receiver and an AD converter. The image sensor transmits 41.7 kHz ultrasonic wave ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...
