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 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 ...

The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Abstract: This paper shows non-contact water level monitoring system implemented using LabVIEW and arduino. Water depth of the tank is measured by Ultrasonic sensor. Hence the water level present in ...

Fans of the bouncing lamp from the Pixar corporate logo will enjoy [Daniel]’s latest project. It’s a motion controlled desk lamp that uses ultrasonic sensors to control its physical position. The core ...

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 ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...
