This project demonstrates the control of an SG90 servo motor using an HC-SR04 ultrasonic sensor and an Arduino Uno. The ultrasonic sensor measures the distance between the sensor and an object. Based ...

If you’re unfamiliar, board-certified dermatologist Michele Green, MD, describes them as handheld devices that use high-frequency vibrations, typically between 20,000 and 30,000 hertz, to exfoliate ...

Sonair’s ADAR One 3D ultrasonic sensor provides spatial awareness for robotic systems, enabling detection of people and obstacles across multiple heights in shared work environments. Sonair has ...

Researchers have demonstrated they can make coffee comparable to conventional espresso using ultrasonic waves. Because the process doesn’t need hot water, it consumes 75 percent less energy. The ...

Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether you want to measure ...

Looking ahead: Midjourney built its name on AI-generated images. Now, it is talking about something far more ambitious: scanning the human body. In a post this week, the company outlined plans for a ...

Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using only sound. Without electricity, electronics, or batteries. The sensors are ...

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without directly attaching ...

Editor’s Note: When I first published this, I stated that R2 would be dropping ultrasonic sensors and moving to a vision-only setup. After going back and revisiting Rivian’s Autonomy Day presentation ...

Measuring distance without touching anything might sound like advanced robotics, but it's actually one of the most common sensing techniques in electronics. Car parking assistance systems, ...
