Prototype of Sand Concentration Measurement System Using the Internet of Things

We constructed a simple airborne sand dust concentration measurement system by combining a commercially available dust sensor with a microcomputer and cloud-type Internet-of-things service. The system uses an optical dust sensor to measure the dust generated when strong winds blow on farmlands. The measurement at observation points on the map can be displayed by means of different colored markers, denoting different dust concentrations, by creating a new web service using a JavaScript open-source library. In addition, information useful for the daily life of residents can be displayed, such as whether laundry can be taken out to dry.
