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 ...

VCC This pin is used to supply power to the sensor. It typically requires 5V DC power supply. Trig (Trigger) This pin is used to send a trigger signal to the sensor. When a HIGH signal (usually 5V) is ...

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 ...

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 ...
