This project is based on Arduino UNO and an ultrasonic sensor. It is designed to measure distance and trigger a buzzer if the measured distance is below a certain threshold. The ultrasonic sensor ...

This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?

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 ...

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 ...

Abstract: An advanced blind assistance device integrates an ultrasonic sensor, Arduino UNO board, buzzer, and GSM module to create a cost-effective solution for enhancing the safety and autonomy of ...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle-avoidance and distance-measurement systems. The ultrasonic range finder measures the ...

Abstract: Early stage failure signals of rotating machinery are weak, and only high-sensitivity sensors can detect the mechanical damage status. This article proposes a design method for a highly ...
