The objective of this work is to develop a low-cost data acquisition system, which aims to optimize the anaerobic biodigestion process in an Indian model biodigester prototype, by monitoring the main parameters of the process. In this development, we decided to create a system from scratch, including the entire measure-process-show procedure using hardware tools and free software as means of reducing costs. This platform must be capable of obtaining analog data from the sensors arranged in the biodigester in long periods for the creation of more accurate reports. The system must be able to send this information to a Web server, so these values can be continuously tracked anywhere with access to the internet. The monitoring must be done in a hybrid application for An-droid, iOS and web browser.
