From navigation to solar weather forecasting, many different areas of research require space-based sensors to measure Earth's magnetic field as accurately as possible at any given moment. So far, ...

For 4,000 years mapping showed us the world from a new point of view. Modern AI enabled maps are now running the world.

A team of researchers from Argonne National Laboratory, the Pritzker School of Molecular Engineering at the University of Chicago and the University of Wisconsin-Milwaukee, has devised a pathway for ...

As spring deadlines settle and students like you look to reactivate dormant tinkering skills, the Arduino ecosystem in 2026 offers a streamlined path back to hands-on engineering. The Circuit ...

A team of researchers used tiny imperfections on a diamond lattice to successfully measure Earth’s magnetic field. The ...

Lidar systems use pulses of infrared light to measure distance and map a 3D scene with high resolution, allowing autonomous vehicles to rapidly react to obstacles that appear in their path. But ...

AI is reshaping how Arduino and IoT sensor systems are built, debugged, and maintained. From mobile-enabled vibration alerts to self-learning calibration, developers can now achieve better accuracy ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Editor’s note: In this Design Idea (DI), contributor Bonicatto designs a digital filter system (DFS). This is a benchtop filtering system that can apply various filter types to an incoming signal. The ...

Patients are being warned to stop using some glucose monitors made by Abbott Diabetes Care after the company found malfunctioning sensors may be linked to hundreds of adverse events and several deaths ...

The fuel and spark strategies for a supercharged street car are only as smart as the sensors feeding data to the ECM. Here’s what happens when a blown beast’s MAP sensor can’t keep up, and how to fix ...
