Diseño e implementación de un sistema de monitoreo para el control de nutrientes, PH, C.E., temperatura y flujo de agua, en hidroponía mediante el uso de sistemas embebidos, ubicado en el departamento de horticultura, de la Facultad de Recursos Naturales, de la Escuela Superior Politécnica de Chimborazo

Abstract

The design and implementation of a monitoring system for the control of nutrients, ph, ec, temperature, and water flow in hydroponics using embedded systems was efficient in the acquisition of data in the horticulture department of espoch. It was because of the interface implemented between labview and arduino, obtaining greater efficiency than with the use of portable pocket instruments. In this way, it was verified that the working values of the implemented system are within the range of 5.5 and 6.5 for the ph, 1200 ms/cm and 2200 ms/cm for electrical conductivity, 24 ° c and 26 ° c for temperature. Through the 5% tukey test, the two data collection methods were compared, and the implemented system was validated, with which values of 6.35 were obtained for ph, 1872.91 ms / cm for electrical conductivity and 24.89 ° c for temperature. There were no significant differences with the measurements obtained with portable instruments, which were 6.4 for ph, 1903.2ms / cm for electrical conductivity and 25.07 ° c for temperature. It could be stated that the results obtained statistically are the same, so it was recommended to use the implemented monitoring system since it was accurate. The values obtained for both ph, c.e., temperature of the nft hydroponic system were reliable. They were compared with a measurement standard acquired manually, demonstrating that the implemented system was efficient, complying with the requirements of the espoch horticulture department.
