Paper Abstract

There are many applications requiring chemical analysis in the field and analytical results in (near) real-time. For example, when accidental spills occur. In others, collecting samples in the field followed by analysis in a lab increases costs and introduces time-delays. In such cases, “bring part of the lab to the sample” would be ideal. Toward this ideal (and to further reduce size and weight), we developed a relatively inexpensive, battery-operated, wireless data acquisition hardware system around an Arduino nano micro-controller and a 16-bit ADC (Analog-to- Digital Converter) with a max sampling rate of 860 samples/s. The hardware communicates the acquired data using low-power Bluetooth. Software for data acquisition and data display was written in Python. Potential ways of making the hardware-software approach described here a part of the Internet-of-Things (IoT) are presented.
