The Control Model for Environmental Factor Effecting on Growth of St. John's Wort

St. John's wort (Hypericum perforatum L.) is a perennial herb and it has been used in medicine to treat various diseases. In terms of growth, it has required environmental factors and weather to appropriate. Thus, this paper presented the control model for environmental factor effecting on growth of St. John's wort by using two approaches. Those are the designed greenhouse and using Internet of Thing (IoT) and application. This work applied IoT as using the Wireless Sensor Network (WSN) and various sensors to measure, monitoring the change and control environmental factors in the greenhouse through the mobile and web application. This paper focused on three factor i.e. temperature, air humidity, and light. The proposed system was installed and tested in real situation at PSU farm. The result showed that the design and construction greenhouse can assist to control factors for the plant. The designed greenhouse can support to suitable adjust the factors of growth of St. John's wort. Moreover, the developed IoT and application can improve and controlled the factors better.
