Nejayote is the residual water from the corn nixtamalization process, this is considered a pollutant when it is discharged into the public sewer system due to its high demand for oxygen, high temperature, and pH. There is Biohydrogen production with the use of dark-phase fermentation of nejayote in the presence of clostridius. To determine the concentrations of the different gases produced H2, CH4, CO2, was designed and build a data acquisition system on Lab View development platform, using MQ-X type sensors and Arduino UNO prototyping board. Was adapted an airtight plastic container with capacity of 30 ml with special nozzles to allow multiple needle entries and injections of different samples. This device allows us to quantify the biohydrogen obtained from the various concentrations used in the reactors to obtain the optimal mixture.
