The present research work arose from the need to study the influence of various beneficial microorganisms in the production of biogas under controlled temperature conditions. In addition, a biodigester prototype was designed using an embedded system with Arduino. To control the internal temperature, a 1000-Watt resistor was used for internal heating, using an electronic device such as the DS18B20 temperature sensor. The research began in july 2019 and culminated in March 2020. For the trial, a 60-liter batch biodigester was designed with a real-time internal temperature control system using the Arduino Mega 2560 microcontroller. Manure was used as inoculum. of hen from the farm of the poultry program of La Molina National Agrarian University. Three treatments were analyzed using the same substrate, which consisted of a mixture of: chicken manure, food waste from the dining room of the National University of Engineering and sawdust. The treatments were: Treatment 1 (Treatment C), the substrate was pre-composted, the biodigester was loaded and water was added; Treatment 2 (Treatment EM 1), bocashi fertilizer was made to the substrate with beneficial microorganisms, obtained according to the methodology of Cárdena (2012), the biodigester was loaded and 50% (of the liquid volume of the biodigester) of water and 50% (of the liquid volume of the biodigester) of wastewater from the Residual Water Treatment Research Center (CITRAR) of the National University of Engineering; Treatment 3 (EM Treatment 2), bocashi fertilizer was made to the substrate with beneficial microorganisms, obtained according to the methodology used by the Nicaraguan Institute of Agrarian Technology (INTI), the biodigester was loaded and 50% (of the liquid volume of the biodigester) of water and 50% (of the liquid cantidad were added. biodigester) of wastewater from the Wastewater Treatment Research Center (CITRAR) of the National University of Engineering. The objective is to compare the volume and quality of the biogas produced. The highest volume production was obtained in Treatment EM 1 in comparison with Treatment C and Treatment EM 2. The maximum values in the results of the percentage of methane of the biogas produced were: For Treatment C, 58.4% of CH4; for EM Treatment 1, 62.3% CH4; for EM Treatment 2, 62% CH4.
