Environmental contaminants like fluoride, lead, and pesticides exist all around and even within us. While researchers have simple ways to measure concentrations of such contaminants inside lab ...

ams launched its color sensor intended for portable devices which is ideally suitable for light source detection when operating under a wide range of light sources, the TCS3490. Providing accurate ...

Not all poisonous gases have a smell or a color. But a tiny grid of pastel- and candy-colored squares that effectively “sniffs” out hazardous chemicals in the air such as chlorosarin — a highly toxic ...

A team of researchers has developed a new biosensor that turns the invisible signals into visible color changes to detect urea levels in a simple way. The sensor works by combining gold nanoparticles ...

A quick and simple fluorescent test can detect trace quantities of benzene in both liquid and vapor form. The new test uses paper strips impregnated with a supramolecular host-guest assembly system ...

Designed to provide ultra-long range color verification, the BFS 30M color sensor offers a detection range of 30-100mm, with a recommended operating range of 50mm. The BFS 30M’s high switching ...

Although ultrasonic sensors have been around for several decades, their popularity in sensing applications continues due to their capability, flexibility and relatively low cost. Products like ...
