The use of electrochemical sensors proved to be efficient in terms of accuracy and capability to measure the analyte concentration even in the field in a short time. Thus, in this paper, we propose a mobile system, including hardware and software, to facilitate the use of a potentiostat commonly used with an electrochemical sensor. The software expressed by a mobile application allows the control of the developed wireless potentiostat. It assures the remote selection of specific parameters associated with implemented voltammetry methods. The APP enables the control of multiple potentiostats simultaneously that materialize the electrochemical sensor network. The developed software can also store the electrochemical data on the cloud. The implemented mobile system allows to perform real-time measurements for different applications, including healthcare, agriculture, or water quality.
