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 ...

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 ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

Making this keyboard is way much harder than I expected, so I upload my project and code. Hopefully it can help more people. After several weeks of woe and pain, here's the only way for a Arduino UNO ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
