Sin embargo, tienen altos costos, por lo que se requiere el diseño, construcción y operación de aparatos con precios accesibles para pequeños productores. El objetivo del presente trabajo fue, diseñar, construir y verificar un prototipo de germinador de bajo costo, bajo las directrices de diseño de un prototipo. Dicho germinador, se construyó usando materiales disponibles en la región y es capaz de controlar automáticamente la temperatura y fotoperiodo mediante los circuitos W1401 y Tem-8 48386 respectivamente. Además, mediante conmutadores simples se puede controlar la intensidad lumínica. Adicionalmente, se construyó un verificador de temperatura con una tarjeta Arduino Uno. El sistema de verificación permitió el monitoreo de los cambios de temperatura en tiempo real (cada minuto). El prototipo se probó germinando semillas de Capsicum chinense, usando distintos volúmenes de agua de imbibición. De acuerdo con los resultados obtenidos, el prototipo construido se ajusta a los requerimientos recomendados tanto por la International seed testing association (ISTA), como por la Food and Agriculture Organitation (FAO) para la evaluación de semillas, pero, además mostró un rendimiento mayor, en comparación con una incubadora comercial y aun costo de construcción y operación muy menor.]]></p></abstract>

However, they have high costs, so the design, construction and operation of devices with accessible prices for small producers is required. The objective of this work was to design, build and verify a prototype of low cost germinator, under the guidelines of a prototype design. Said germinator was built using materials available in the region and is able to automatically control the temperature and photoperiod through circuits W1401 and Tem-8 48386 respectively. Furthermore, by means of simple switches, the light intensity can be controlled. Additionally, a temperature verifier was built with an Arduino Uno card. The verification system allowed the monitoring of temperature changes in real time (every minute). The prototype was tested by germinating seeds of Capsicum chinense, using different volumes of imbibition water. According to the results obtained, the built prototype is adjusted to the requirements recommended by the International seed testing association (ISTA), as well as by the Food and Agriculture Organization (FAO) for the evaluation of seeds, but also showed a higher yield, compared to a commercial incubator and even a very minor construction and operation cost.]]></p></abstract>
