The use of fermenters is common in various biotechnological processes. Currently, a fermenter or bioreactor can monitor physical and chemical variables which are displayed to the operator through a screen. In addition to the construction materials of a bioreactor, nowadays its acquisition is expensive and inaccessible for educational and research purposes. To address this problem, the Fermenta V1.0 interface was designed and developed to simulate a bioprocess performed by a fermenter, using a Nextion touch screen and Arduino UNO; for its programming, the appropriate integrated development environments were implemented. The interface was able to emulate different electronic devices such as sensors, solenoid valves, peristaltic pumps, lighting, and agitation. In this first stage, the starting point is established to facilitate the coupling of the Fermenta V1.0 interface with various sensors oriented to the monitoring of a fermenter. With the incorporation of the electronic devices to the interface, it will be possible to adapt the system (interface-sensors) to a biotechnological process where the use of a fermenter is required and the need to monitor temperature, dissolved oxygen, pH, CO2, lighting, agitation.
