Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

Code to measure distances using an ultrasonic sensor connected to pins 9 (trigger) and 8 (echo) on the Arduino Uno. The distance is calculated in centimeters and inches, and displayed on the Serial ...

This project involves developing a simple application using an Arduino and an ultrasonic sensor to measure the speed of an object. The application will calculate the speed based on the time taken for ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using ...

The system consists of an ultrasonic sensor, an Arduino board, and a webcam. Speed and location of vehicles are determined accurately by using ultrasonic sensor, and the distance is calculated over a ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...
