Automated Hydroponics Systems, A Review and Improvement

Harmful chemicals in weedicides, pesticides, and artificial coloring which are used in commercial crops are an issue for many consumers and buyers, everyone desires and deserves healthy food. This will create a need or demand for healthy crops without pesticides. One solution for this problem is Hydroponics in which plants are grown without soil while nutrients are supplied through water, however, due to the busy nature of people and more and more people moving away from agriculture, researchers came up with an automatic way to grow hydroponic plants. The nutrient-rich solution is pumped with the help of a motor while sensors manage temperature, electrical conductivity, humidity, and light with the help of a microcontroller. Grow lights are installed to grow plants in an indoor environment. In this paper, we are going to discuss the previous works in the fields of automation of hydroponics and propose our architecture for an automated hydroponic system.
