HUMID-LIGHT moisture sensor for real-time air quality monitoring

Overview

HUMID-LIGHT is an innovative optical sensing device designed for accurate and rapid measurement of moisture content through powders or porous media. It utilizes speckle imaging, a technique involving the scattering of coherent light by a wet colloidal powder, which enables high-speed detection of environmental condition changes with exceptional accuracy. This sensor provides significant advantages over traditional humidity sensors, offering 10 times better resolution at approximately 0.1% relative humidity and ultra-fast measurement capabilities of less than 5 milliseconds.
