Automatic Irrigation System by using Smart IoT Sensors

Abstract

Traditional ways of manual irrigation are more time consuming and requires lot of human efforts. In order to reduce time, efforts and cost, modern techniques need to be integrated in farming. In this study one such modern solution has been proposed to minimize human efforts and reduce the time by automating the process of watering the plants when it is required. In the proposed technique the soil moisture and water level in the tank is sensed by using smart IoT devices and water is supplied to the plants when it is required. The soil moisture sensor monitors the actual level of water in the soil. When the moisture level of the soil reduces to the predefined threshold value, it switches on the water pump automatically if there is sufficient water in the tank. Further, the system is also integrated with a smart mobile application where farmer can monitor moisture level of soil, water level in the tank and auto On/Off the switch of water pump as per requirement. In case if farmer want to On/Off the pump manually, such facility is also integrated in the smart mobile application. The smart integrated model developed and tested successfully on different soils having different level of moisture and by varying the level of water in the tank.
