Wireless sensor network for real-time monitoring of temperature, humidity and illuminance in an orchid greenhouse

Abstract

Some countries in South America such as Ecuador, Colombia and Peru have increased their presence in the production and export of orchids. Ecuador has 14% of the world's species and in 2014 its orchid exports increased 8%, this shows the importance of this product for the country. An orchid greenhouse is a botanical garden specialized in the cultivation, preservation and exhibition of orchids, these places require that physical variables such as ambient temperature, humidity and illuminance to be continuously monitored and controlled for the proper growth of orchids. The present work proposes the design, prototyping and deployment of a wireless sensor network for the monitoring of physical variables in the Municipal orchid greenhouse of Loja, based on open hardware technology. As a result, two prototypes were implemented: one from the variable monitoring node and the other from the central node for visualization and recording of variables. For the validation of the prototypes, performance tests were carried out in the field. Approximately 3000 samples were obtained with a 100% reliability rate in the transit of the data within the process of acquisition, transmission, reception and storage.
