Automated Hydroponic System for Deep Water Culture to Grow Tomato using ATMEGA328

This paper presents a way to automate the growth of plants with hydroponics in deep water culture using a simple algorithm to maintain the pH level in water and supply nutrients to the nutrient solution when necessary. Despite hydroponic crops being highly nutritious and free from pest, it is difficult to grow hydroponic crops since it requires constant attention to maintain the suitable conditions for the plants and requires knowledge about the hydroponic system to grow them. A sensor is used to log the data from the pH meter and electrical conductivity meter. This data is then used to identify different phenomena and notification is sent to a person. The automated system is designed to take the required action when a certain phenomenon occurs. Index Terms - Hydroponics, Automation, Soil-Less Culture, pH, Nutri-Culture
