This is an Arduino project using an HC-SR04 Ultrasonic Sensor and LEDs to measure the distance of objects, similar to a scale. When an object comes close to the HC-SR04 ultrasonic sensor, it indicates ...

Measure distance using an ultrasonic sensor and display it on the Serial Monitor. Ultrasonic Distance Measurement with Arduino This project demonstrates how to use an HC-SR04 ultrasonic sensor with an ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

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 ...

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 ...

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 ...

Makers, developers and enthusiasts building distance related projects may be interested to know that the HC-SR04 ultrasonic sonar distance sensor is now available to purchase directly from the ...

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 ...
