Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

There are many types of magnetic field sensors on the market. A brief list would include (but not be limited to) these, with the more exotic devices first: The MEMS solutions are gaining market share ...

Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object approaching the sensor changes magnetic flux through ...

Quantum Sensors Boost Magnetic Navigation As An Alternative To GPS is available to both Aviation Week & Space Technology and AWIN subscribers. Subscribe now to read this content, plus receive critical ...

The Compact Magnetic Sensor (CMS) is a low cost, low power, weatherproof device that detects small changes in Earth’s magnetic field. It is capable of running in battery mode for a week in various ...

Researchers used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes ...

As the EV market grows, so does demand for robust magnetic field sensors within these vehicles. Stray magnetic fields may diminish the accuracy of these sensors, though, which is where active ...

The new magnetic sensor is inexpensive to make, works on minimal power and is 20 times more sensitive than many traditional sensors. A team of Brown University physicists has developed a new type of ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...
