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 ...

Here is a design concept for a cheap single point optical liquid sensor that can detect the presence or absence of certain colored liquids inside a transparent tube. It can be tailored to output a ...

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next ...

The LiQuilaz ® II optical liquid particle counter from Particle Measuring Systems is a volumetric monitor that has been specifically developed with a range of sizing sensitivities as low as 0.2 µm. It ...

Carbon nanotube: these structures have been used to create a new and flexible light sensor. (Courtesy: iStock/theasis) A flexible, ultrathin optical sensor that uses carbon nanotubes to convert light ...
