LPG gas is supplied in pressurized steel cylinders. As this gas is heavier than air, when it leaks from a cylinder it flows along floor and tends to settle in low spots such as a basement. This can ...

For over four decades, gas-leak-detection sensor tech has remained relatively unchanged and proven costly and often unreliable. Advances have changed the landscape, though, with sensors now including ...

Detecting the presence of harmful gases was a necessity for early miners as well as manufacturers and consumers at the start of the industrial revolution. One of the first gas detectors was a flame ...

Micro-thermal conductivity detector (µTCD) gas sensors work by detecting changes in the thermal conductivity of the surrounding medium and are used as detectors in many applications such as gas ...

Controlling environmental gas pollution has become critically important as poor air quality has significant health and economic impacts on modern society. Novel gas sensing devices based on ...

Ammonia (NH 3)—the second-most-produced chemical globally—has proven to be highly important in furthering human civilization over the centuries, both in terms of technological capabilities and ...

Researchers have developed the first fully-integrated, non-dispersive infrared (NDIR) gas sensor enabled by specially engineered synthetic materials known as metamaterials. The sensor has no moving ...

Sensors that measure air flow, air quality, and chemical makeup are being deployed increasingly for both indoor and outdoor environmental monitoring, in homes, automobiles, and industrial facilities.
