AB  - Most of the complex environmental controls used in smart greenhouses in Korea are controlled based on data collected from environmental sensors located at specific locations inside the greenhouse. The internal environment of a vinyl greenhouse frequently changes depending on the external environment flowing in. Even though different environmental conditions exist in the same greenhouse, controlling them with a single value causes non-uniformity of the internal environment and causes problems such as increased crop cultivation period and reduced production. In this study, the temperature uniformity inside the greenhouse was analyzed using standard deviation, and the sensor location that estimates the representative value inside the greenhouse was derived using clustering. When the optimal location of sensors was determined in real time using the system of this study, the optimal number of sensors was found to be 2 to 4, and the optimal location of sensors varied depending on the standard deviation of the temperature inside the greenhouse. By configuring the existing limited wired data collection device with a wired and wireless sensor so that it can move flexibly, it is expected that research on precise greenhouse control that adapts to the environment according to changes within the greenhouse will be possible.
