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

Abstract

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