Development of Smart Greenhouse System for Hydroponic Agriculture

Food availability is a very important problem to be resolved due to the growing world population. The problem faced is how to increase agricultural production. In addition, how to reduce the use of pesticides so that they are not harmful to humans. One solution to overcome this problem is to create a smart greenhouse system. Farming in this smart greenhouse system does not use pesticides. This study aims to develop smart greenhouses for hydroponic farming based on the Internet of Thing (IoT). In this study, we also measured the chlorophyll content of mustard leaves grown hydroponically in a greenhouse system to determine the nitrogen status of the mustard plant. The controller unit of this system is the Arduino Mega2560. Data on temperature, humidity, TDS, PH, light, and actuator conditions (pumps, lights, fans, sprayers, and valves) are stored on the real-time database firebase. Data communication between the Arduino Mega2560 and the Firebase platform uses an internet connection via the ESP-01 module. The results showed that all components such as sensors and actuators were functioning properly. Environmental conditions in the greenhouse can be monitored via an application on a smartphone and all actuators can be controlled via an application on a smartphone.
