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 ...

This project demonstrates how to use an HC-SR04 ultrasonic sensor with Arduino and ESP32 to measure distances accurately and integrate them into DIY electronics or IoT projects. The ultrasonic sensor ...

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 ...

Abstract: 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 ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...
