This paper presents the design of the Internet of Things (IoT)-based greenhouse traceability model for the tracking and recordkeeping of seedlings and other agricultural products in the germination and growth stages. Traced products are generally of high quality and high commercial value, making the voluntary adoption of traceability processes for the market in processed products and trade in fresh products more common today. The transmission of diseases to humans, along with the cases of chemical poisoning, provided the motive for changes in trade relations between the countries and in the manner of assessing consumer safety. The model allows the tracking of variables, such as luminosity, humidity, temperature, and water consumption, thereby revealing overall water use, growth patterns of the plants, and the timeline for harvest of produce. The system enables automated control of the indoor environment of the greenhouse using an irrigation system or temperature control and presents the main outline of internal traceability of agricultural products from seed to final produce. By means of an IoT platform, this greenhouse design finally facilitates a novel analysis of the behavior of a number of species that comprise the local agriculture in one region of Colombia.
