A research team develops a real-time humidity sensing optical sensor. The response time of the new sensor is 10,000 times faster than the conventional sensors and can be mass-produced at low cost. The ...

The circuit shown in the figure measures relative humidity in air at the low temperatures found in applications like cold storage of food items and greenhouses. Instead of using electrical signal ...

A research team develops self-powering, color-changing humidity sensors. Applicable to various fields including smart windows, health care and safety management. Smart windows that automatically ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

The Hong Kong Polytechnic University (PolyU) has developed new side-hole polymer optical fiber sensors, which can be used in multiple medical treatments without the drawbacks of other optical fibers ...

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 ...

(Nanowerk News) The Hercules beetle native to South America has a fascinating trait of changing its shell colors depending on the external humidity conditions. This is because the inside of the beetle ...
