Low-Cost Acquisition System for a Photobioreactor Using Open-Source Raspberry Pi

<p>Code used to read the sensors, and light control</p>

This application, developed in Python, performs the task of reading the sensors placed in a bubble column bioreactor. The measured variables are temperature, dissolved oxygen, carbon dioxide, and liquid level. Additionally, it controls the light intensity and spectrum. The executable of this application is an interface divided into three screens. The first screen displays the measurements from each sensor, the second screen shows the light control with the variables that can be adjusted, and the third screen provides the option to save data, allowing the user to select the storage path. This is the latest version of the application; however, we will continue adding improvements.
