A key aspect in bioprocesses is the monitoring and control of the physical variables that affect it. Hence, the tailor-made software development, capable of: reading, storing and graphing information of process variables is of vital importance to users. This article presents the development of SICOAVENZ (Automatic Variable Control System for Enzymatic Reactions), an application that communicates with a data acquisition board, to which sensors and actuators that allow interaction with a

... r are connected, in which an enzymatic extract is obtained. The software was developed under object-oriented programming using C # (C Sharp). Where it is shown that implementing low-cost systems using efficient, easy-to-manage and potentially scalable software architectures, is possible. It was also possible to develop a software that allows: 1) control pH and temperature variables, 2) keep a constant record of the behavior of these variables, 3) generate reports in Microsoft Excel, 4) handle information according to the role (Administrator or User) and 5) to observe through a video camera the experiment in progress. This development is characterized because it can: 1) have a wide range of application in different fields of action, 2) ensure reproducibility of the process and 3) give independence to scientific personnel.
