Abstract- Water is the basic need for the survival of the humans and many parts of world are still facing scarcity of water. Therefore, it becomes very crucial for us to save water. This system can be one of the tools to do so. Agriculture is one of those areas which consume a lot of water. Irrigation is a time-consuming process and must be done on a timely basis. The aim of the article is to develop an auto irrigation system which measures the moisture of the soil and automatically turns on or off the water supply system. In the proposed system, the data of the moisture content updated for regulating the water pump. This paper will give a clear knowledge about the suitable method for the better irrigation.
Keywords—Moisture sensor, Arduino, Microcontroller.
