Sistema de control y monitoreo electrónico en la elaboración de abono orgánico

Abstract

ABSTRACT In the present work of investigation I realize a system of control and electronic monitoring of two systems of decomposition in different aerobic and anaerobic means, by means of the utilization of organic residues, in the aerobic system I realize the elaboration of organic fertilizer whereas in the anaerobic system I determine the formation of gas methane taking into account each one of the parameters that intervene in every system of decomposition. The aerobic decomposition system is constituted by a composter with organic waste for the formation of organic fertilizer, the parameters that intervene for the formation are temperature, humidity and pH, in addition, a system of eight biodigesters was made with four different types of excreta in each one and their respective replicas to carry out the study of anaerobic decomposition that is generated taking the respective control of its parameters such as: temperature, humidity and generation of methane gas CH-4 formed in each biodigester. The electronic system consists of a sensorization stage in which the ds18b20 sensor, capacitive humidity sensor v1.2 and pH sensor are used for an aerobic environment and BME280 sensors and MQ-4 sensors for an anaerobic environment. And a control stage through the actuation of solenoid valves, the reading of these values are stored in a phpmyadmin database and then sent to an external AWS service to be monitored. The design of the web page is user friendly, it allows to review the current status of the compost and the 8 biodigesters providing information on the time it takes to decompose, form organic fertilizer and methane gas, also allows us to visualize through graphs each of the parameters, a report of data and alerts for each phase for preventive action. In addition, the operational maintenance of the water expulsion for filling the tank and for the drip system inside the compost in the aerobic environment and the expulsion of methane gas for the anaerobic environment is performed.
