In recent years, water crisis in Asia is reaching an alarming proportion that might very soon attain the worldwide global crisis and there is an utmost need to save water. The water crisis occurs due to the increase of population, poor water harvesting, and water wastage in the manufacturing industries, process industries and agriculture sector. Therefore, each sector requires a mechanism to reduce the water wastage and save it for future needs. In this paper, an efficient irrigation system is designed to reduce the water wastage in agriculture fields. Due to the farmer’s irregularity and negligence, they leave the motor turned ON for several hours which will lead to wastage of water and more power consumption. Similarly, they forget to switch ON the motor, which also leads to the damage of crops due to insufficient water supply. The proposed system controls the flow of water in the fields in accordance with the intensity of sunlight and moisture content present in the soil. This system uses the microcontroller (Arduino UNO) assisted with LDR (Light Dependent Resistor), capacitive type moisture sensor and DHT 11 (temperature and humidity sensor). Based on the sunlight intensity and moisture content present in the soil, the Arduino UNO is programmed to turn ON/OFF solenoid valve connected to the pipeline that controls the flow of water in the agricultural fields. Thus the proposed system can operate automatically and supply water to the fields whenever needed without any human intrusion. Further, a Wi-Fi module ESP8266 is connected such that the solenoid valve can be operated manually through mobile phones/laptops based on the measured parameters if required.
