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.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

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 ...

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 ...

A network of 74 sensors — 57 of which were ultrasonic sensors developed by the University of Augsburg (shown at top and as light blue dots in upper and low mold halves) — were used in the T-RTM ...

Ultrasonic Sensor Interfacing using Altera Cyclone IV FPGA Project Overview This project demonstrates the interfacing of an ultrasonic distance measurement sensor with an Altera Cyclone IV FPGA board ...

The ultrasonic beam from this sensor penetrates the skin, detects signals reflected from the vessel walls, and measures changes in vessel diameter. Using this principle, it measures the real-time ...
