This study was conducted to make use of Korea Meteorological Administration(KMA)’s Automatic
Weather Station(AWS) data to operate smart green greenhouse. A Web-based KMA AWS data receiving
system using JAVA and APM_SETUP 8 on windows 7 platform was developed. The system was
composed of server and client. The server program was developed by a Java application to receive weather
data from the KMA every 30 minutes and to send the weather data to smart greenhouse. The client
program was developed by a Java applets to receive the KMA AWS data from the server every 30
minutes through communicating with the server so that smart greenhouse could recognize the KMA AWS
data as the ambient weather information. This system was evaluated by comparing with local weather data
measured by Inc. Ezfarm. In case of ambient air temperature, it showed some difference between virtual
data and measured data. But, the average absolute deviation of the difference has a little difference as less
than 2.24℃. Therefore, the virtual weather data of the developed system was considered available as the
ambient weather information of the smart greenhouse.
