Diseño e implementación de un prototipo electrónico germinador de semillas aplicado para la producción de brotes para el área alimenticia.

Abstract

It was designed and implemented an electronic seed germinating prototype applied for the production of sprouts for the food field. It consists of four stages: data acquisition, action, control and reception: and information display. The first stage collects the information regarding temperature, relative humidity and luminosity, the action stage is responsible for stabilizing the microclimate of the germinator. The control and reception stage is made up of an Arduino mega 2560 PRO which is in charge of receiving and processing the information. Finally, the last stage consists of supervision through a human machine interface (HMI) created in Nextion Editor and remote monitoring of the microclimate parameters of the germinator through a mobile application developed in Android Studio. From the tests carried out on the characterization of the temperature, humidity and luminosity sensors, relative percentage errors of 1.90%, 1.85% and 0.12% respectively were obtained. establishing that the results are between "good" and "very good". From the repeatability tests of the prototype based on the coefficient of variation, a maximum value of 0.88% was determined, which implies little variability according to the authors' report. According to experts in the food area, who applied quality tests on the sprout produced with the prototype, determined its excellent quality, with a degree of acceptability "7" that defines the best organoleptic characteristics, much higher than products marketed in the area. From what has been analyzed, it is concluded that the developed prototype is competitive with similar commercial teams. It is recommended to incorporate artificial intelligence to the prototype, which facilitates the quality in the selection of the seeds before and during the germination process.
