A Low-Cost Arduino based Automatic Irrigation System using Soil Moisture Sensor: Design and Analysis

A low cost Arduino based Automatic Irrigation system using Soil moisture sensor is presented in this paper in which the soil moisture sensor gives it's output depending on the conditions of the soil and later with the help of Arduino it get's worked. As agriculture is given higher priority in the life of an economy so for the better agricultural growth, water is essential factor. Lack of enough water and excess of water leads to damage of plants. So we need an effective and efficient technology for better farming. Thus, the usage of a low cost arduino based automatic irrigation system using soil moisture sensor is expected to be useful to for the irrigation process in agriculture. This system requires an Arduino-UNO which contains ADC converter in it. A soil moisture sensor is the main component in this system which is used to measure the conditions of the soil like whether the soil is dry or wet. For displaying the conditions of the soil, 16×2 LCD display is the better choice to display and at last a motor is used to pump the water to the plant or crops.
