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 ...

New data offers insights into how heat is affecting different communities across Hawaiʻi Island. HPR's Savannah Harriman-Pote talks to the team behind the project.

Three cheap hygroscopic salt solutions on carbon nanotube sensors distinguish nine toxic gases, including warfare agents, without engineered receptor molecules.

It's a real solution for efficiently drying laundry indoors ...

Lilypad Paint has a premium finish and also functions as a desiccant, pulling water vapor out of the air when humidity rises. A gallon can absorb about 13 ounces of vapor, roughly what a hot shower ...

Aqara's advanced presence sensor drops to AED 264 on Amazon.ae from AED 399. Unlike basic motion sensors, this uses mmWave tech to detect you even when sitting still. Works with HomeKit, Alexa, Google ...
