Abstract
In this paper, a portable potentiostat, based on the ad-hoc designed Analog Front End (AFE) and equipped with a microcontroller including a Wi-Fi network processor is presented. Unlike the most common portable sensors that lean on a smartphone or personal computers, the device exploits the cloud service for data storage. This feature enhances the device portability and makes it suitable for various semi-quantitative and quantitative analyses. The effectiveness of the proposed sensor was validated with measurements on known concentrations of potassium ferri/ferrocyanide redox probe in aqueous solution. The resulting calibration curve was compared with the results reported in the literature, showing an R2 value comparable or even higher. This result is very promising for both semi-quantitative and quantitative analyses.
