Paper Abstract

There are many applications requiring measurements on-site for example when accidental spills occur either outdoors or on the floor of IoT-enabled smart-factories (e.g., Industry 4.0). In other cases, a portable, fiber-optic spectrometer may be required for “bringing part of the lab to the sample” types of chemical analysis applications. Conceptually, there two approaches that can be used to put an optical spectrometer on IoT. One, is to design it from the ground up. The other, is to purchase a portable, battery-operated fiberoptic spectrometer; to use the manufacturer’s software (without any modification), and to employ a wireless connection, so that user interface and data-display will take place on the screen of a smartphone. In this paper, a dual-processor approach was taken to accomplish these tasks, as will be described in some detail.
