Wherever hydrogen is present, safety sensors are required to detect leaks and prevent the formation of flammable oxyhydrogen gas when hydrogen is mixed with air. It is therefore a challenge that today ...

I spent several weeks testing Withings’ BeamO thermometer to see who could benefit the most from its futuristic design.

What use is a sensor that's wrong?

An international collaboration involving researchers from the University of Innsbruck has developed a novel luminescent material that enables particularly robust and precise optical temperature ...

I love the Pi, but it's not always the best tool for the job.

Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors ...

It happens each year when the weather turns cold: The coats, hats, sweaters and blankets come out. The lights come on earlier. And the arguments over how high or low to set the thermostat begin. But ...

A dual resonator graphene sensor measures pressure with exceptional precision and stability, using built-in temperature compensation to maintain accuracy across wide pressure and temperature ranges.

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

A massive heat dome will bring stifling temperatures and oppressive humidity for millions across much of the United States in the coming days. The high-pressure system is forecast to cause widespread ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...
