The ultrasonic radar system operates by integrating an ultrasonic sensor, a servo motor, and a microcontroller (Arduino) to detect and measure the distance of objects within its range. The ultrasonic ...

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 ...

Connect a 9V battery to Arduino DC barrel jack to power the Arduino and the ultrasonic sensor. Install a separate battery pack into the battery holder to power the motor driver and the motors. Ensure ...

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 ...

[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]’ ...
