Greenhouse Automation Using Internet of Things in Hydroponics

Abstract

Hydroponics is a technique in agriculture that uses very minimal nutrient material to nourish the plants. In this project it is proposed to connect all the sensors and actuators to the UBIDOTS cloud and make the environment a closed loop system under the concept Internet of Things (IoT). We have used these sensors to create an artificial luminance to provide efficient photosynthesis even in low light conditions/night. The system also focuses on monitoring the temperature and humidity inside greenhouse. Using this ambience values, the weather inside the greenhouse is controlled by actuating the exhaust fan and fogger. The entire project is automated using IoT and the microcontroller used is ESP32 which has an inbuilt Wi-Fi Module for connecting to cloud. All the data will be viewed in UBIDOTS cloud platform in real time. The variations in all the data can be visually seen by the user in the application.
