The growing needs of man and the increasing population of earth causes the scarcity of water. This greatly affects the plants, and the requirement water management is high. Water use has been growing globally at more than twice the rate of population increases in the last century, and an increasing number of regions are reaching the limit at which water services can be sustainably delivered, especially in arid regions. In the present scenario the conventional methods of watering, like flood mode and sprinkler, is not that much effective and is responsible for water wastage. Improper watering systems create breeding areas for disease spreading organisms. Hence, the way watering pants must be smart, and this is achieved by watering plants depending on the necessity of plants and the moisture level of water. This project deals with an automated plant watering system that senses the moisture content of the soil thus determining the necessity of pumping water with the collected data. Also determines the minimum amount of water required to maintain the balance between the soil defensible water and environment parameters.
