A Review on Automatic Soil Water Controller for Different Crops in a Field

Abstract: The efficient use of water in agriculture is one of the most important agricultural challenges that modern technologies are helping to achieve. In a country like India where people in huge number are engaged in agriculture, proper and precise irrigation system can lead to much better productivity. This paper presents a system capable of controlling an irrigation system autonomously. By acquiring soil moisture and temperature data, the system is capable to deliver proper quantity of water at the most different periods of crop growth, through the usage of a Programmable Logic Controller (PLC), optimizing the water supply. This project includes selecting field area as well the crop type in selected field.
