Description: Smart greenhouse is a greenhouse that utilizes ICT to measure indoor and outdoor environmental conditions via sensors without time and place limitation, to analyze the collected information to maintain and manage for proper plant growth. Recently, smart greenhouses have been distributed to farmers through ICT convergence projects in Korea. However, difficulties in operation and maintenance exist because of the variation of environmental controllers, core technologies of the smart greenhouse. Consequently, there is a need to implement and distribute environment controllers that use the same platform. In this study, an open platform for smart greenhouse environmental control system was developed to enhance the accessibility of developers and to implement a smart greenhouse environment controller on the same platform. The open platform for the environmental control system consist of an open source environment controller, a power controller & supply, environmental measurement sensors, and CCTVs. The internal hardware includes a Cubieboard2, base board, A/D input module, relay output module, and isolation input module. The program was developed by using Open API, and made of modules for information collection of environmental sensors, control of actuators, and remote upgrade function. As an open platform environment controller is provided with embedded programs and libraries, a developer using an open platform will be able to apply with their own control algorithms. The performance evaluation results of the open platform became real-time monitoring of temperature, humidity, CO2, wind direction & speed, solar radiation. Additionally, actuators such as ventilation windows, flow fans, heating, and CO2 generators were remotely controlled.
