A pH monitoring system was developed at the “Tecnológico Nacional de México campus Mexicali” as an essential tool for carrying out the Project “Optimization of the harvesting process of the Chlorella sorokiniana microalgae by co-pelletizing with the atoxygen strain Aspergillus flavus and improvement of the lipid content.” The technology used consisted of a wireless sensor network with implementation of the PREEMPT-RM real-time algorithm and a low energy consumption PIC16F886 microcontroller for control processes. The system was able to collect and present data in a graphical user interface through internet connectivity. It provided an effective solution for continuous monitoring and precise pH control, allowing timely adjustments to optimize microalgae harvesting. The pH electrode calibration system was validated with buffer solutions to evaluate its effectiveness and performance, guaranteeing effective response time monitoring. Later it was used for the detection and precise control of the pH in the culture medium and in the biofloculation, finding that a good monitoring system allows immediate actions to be taken to optimize the microalgae harvesting process.
