Abstract

Arduino is an open and low-cost platform that enables interaction with devices featuring various functionalities, such as sensors and modules. For monitoring a benchtop bioreactor, sensors for oxygen, pH, pressure, temperature, among others, are examples of devices applicable in bioprocesses. The Arduino UNO R3 microcontroller was employed to create a system for obtaining dissolved oxygen and pressure data in the bioreactor. An electronic circuit and routines for sensor calibration were developed, along with a programming code allowing the acquisition and storage of data from the sensors. An Autodesk AutoCAD sketch was created to design an experimental setup for calibrating the pressure transducer sensor, which, together with a standard manometer, will form a unified system interconnected to receive identical pressure information applied to the liquid column. The methodology used for dissolved oxygen sensor calibration proved to be effective. The programming code developed for the pressure sensor will be validated through experiments using the apparatus proposed in this study.
