Renewable Energy Based Smart Irrigation System

Agriculture is the primary occupation in India and is called India's backbone. But of late, a lot of problems are being faced in agriculture by the farmers. One of the major problems being water scarcity. As per surveys, almost 20 percent of the agricultural land is wasted due to water scarcity and becomes a barren land. Thus, this research gives an idea of smart irrigation system. This irrigation system uses three sensors namely temperature sensor, humidity sensor and soil moisture sensor, and fuzzy logic is used to operate the solenoid valve. The data from the sensors is then sent to the cloud by using adafruit.io and the farmer can view the moisture level, humidity level and temperature recorded by these sensors. All the operations are governed by an Arduino and the power supply for the Arduino is given by a solar panel which uses LDR (Light Dependent Resistor) and makes it into an automatic tracking system. The crops are grown in two tubs and comparison of growth of plant with automated irrigation and normal irrigation is carried out. (C) 2019 The Authors. Published by Elsevier B. V.
