Why passive ultrasonic offers a unique option of sensing discrete open/close events. How a team used passive, non-electronic metal tag for signal initialization. How they used DSP-based, non-ML, ...

The **HC-SR04 Ultrasonic Distance Sensor** is one of the most popular distance measurement modules used in Arduino, ESP32, robotics, and IoT projects. It measures the distance between the sensor and ...

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 ...

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 ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

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 ...
