DESIGN OF FERTIGATION SYSTEM CONTROL IN GREEN HOUSE BASED ON INTERNET OF THING (IoT)

Abstract - Green house must be able to control the environment with temperature and humidity parameters that are suitable for plant growth. However, manual watering always done at any time, which is time-consuming farmers. Greenhouses modern technology create automatic controls such as sprinklers. Thus, time spent on plants less than system. In addition, farmers can save water has been wasted all this because they do not know condition of requirements plants. An system a DHT 22 sensor used greenhouse environment. With development internet almost over world, giving changes daily human activities. Internet Things (IoT) allows objects connect communicate each other. fertigation device, IOT connects devices solenoid valves monitored via network. IoT built ESP8266 module access internet. The hardware design uses microcontroller method. data then sent online an open-source site acts web server. server controlling monitoring accessed conclusion tool automatically. automatically, greater 30 90%. So maintained properly. controlled WIFI network through Blynk application. Can display status humidity, conditions LCD from anywhere anytime.
