Dustroid is an Online Dust Monitoring system to measure particulate monitor for accurate and simultaneous measurement of PM10 and PM2.5 in the ambient air. It is capable of monitoring various particulate size ranging from 1 micron to 100 microns. It can measure different kinds of dust pollution like Suspended Particulate Matters (SPM), Respiratory Particulate Matters (RPM), and Total Suspended Particulates (TSP). It works on the Active Sampling method to count particulate matters using a highly accurate laser beam. Dustroid can be used for dust monitoring in areas with dust-laden activities like construction, mining, quarrying, ports, metallurgical processes, and many more. The data gathered from the dust monitor can assist in dust suppression automation, for instance, to activate suppressants at the location once the threshold is breached.
