Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

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

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Abstract: An exceptionally sensitive and photothermally tunable polymer microbubble is fabricated at the fiber tip for enhanced ultrasonic detection. A modified acrylate adhesive (MAA) is applied to ...

Blind Spot Management System or BSMS is an IoT-based parking safety project built to help drivers and lot controllers detect blind spot risks in real time. Drivers often cannot see around sharp turns ...

Abstract: Urban flooding remains a critical challenge, exacerbated by inadequate drainage systems and the lack of timely early warning mechanisms. This paper presents a sustainable urban flood ...
