Indoor Hydroponic System Using IoT-Based LED

Abstract

The goal of this research is to design a hydroponic automation system for germination until generative growth based on ESP32 microcontroller, and BLYNK called LOTUS. ESP32 acts as main controller for all sensors and actuators. LOTUS able to control temperature, humidity, irrigation, and automatic lighting. LOTUS uses automatic irrigation with ebb-and-flow method. LOTUS included with LED Drivers that able to regulate the amount of light intensity on LED and provide more power efficient usage level. System successfully manages to reduce temperature, humidity, automatic lighting, and irrigation on time. Results from this research show that reading accuracy of the sensors temperature and humidity are, 99,11% for temperature, 97,275% for humidity, power usage for whole system is 49,6 watt, and adjustable irrigation system.
