The destruction of forests in Panama, the effects of climate change, collectors and illegal trafficking has led to Orchid Peristeria Elata having the status of endangered species. Known in Panama under the name Flower of the Holy Spirit, this orchid has been declared by law as representative element of Panamanian folklore. Despite the efforts made to conserve this orchid in its natural habitat, the results are still insufficient. In this paper we propose using an open source platform for low-cost computing to monitor and control environmental conditions in an unheated greenhouse for the care of the orchid Peristeria Elata. This platform is based on the Web and Arduino technology. Through this platform the monitoring will be done remotely; using sensors, a set of environmental variables will be monitored inside the greenhouse and irrigation mechanisms will be controlled. Using these technologies can play similar conditions this orchid in their natural habitat.
