Arduino Based Automatic Irrigation Control System By Utilizing Moisture Content

Abstract

This work is on development to an efficient and affordable watering system. An automatic plant watering system using Arduino microcontroller UNO R3 is programmed such that it interrupts the signals to the motor. Soil sensor is connected to the pin to the Arduino board which senses the moisture content present in the soil. Whenever the soil moisture content goes down, the sensor senses the humidity change and instructs the microcontroller so that pump can be activated, thus reducing water wastage. Global warming in nowadays is a serious issue. As the temperatures are rising, there is an observable change in the climatic conditions that is not usually found in the region. With the rising sea levels, many part of the world suffer with either severe famine/drought or floods. Due to this unpredictability of water resources, the farmers are un able to get good yields or may spoil the yield by watering the crops more than required. Hence, we intend to find an economical solution by developing a cost-efficient watering system that has the capability of sensing the moisture content in the soil and water them, if needed.
