The main breanch is the next generation which uses the V2.2 lingpiod and is written in C++. (See https://github.com/HankB/GPIOD_Debian_Raspberry_Pi/tree/main/60 ...

MIT engineers have created an ultrasonic device that rapidly frees water from materials designed to absorb moisture from the air. Instead of waiting hours for heat to evaporate the trapped water, the ...

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 ...

Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

You brush your teeth, floss regularly and faithfully wear your retainer every night. But despite your diligent oral health habits, your retainer or mouth guard can get yellowed, cloudy or stained.

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 ...

A new category of sensing technology transforms mobile robot vision from 2D to 3D, improves safety performance and provides 50-80% cost savings compared to traditional, LiDAR-based systems and sensor ...

If you need to measure a distance, it is tempting to reach for the ubiquitous ultrasonic module like an HC-SR04. These work well, and they are reasonably easy to use. However, they aren’t without ...

Potholes are practically present on all roads in Mali. Malian drivers seek to locate potholes on the road when driving. And during night trips in Mali, it is very difficult to locate potholes on the ...

Modern vehicles rely on a massive amount of electrical systems, sensors, and control modules to keep the wheels turning. Some of those devices are well-known, like your car's main computer or engine ...
