In India, outdoor water usage itself averages to more than 9 billion gallons of water each day, specifically for landscape irrigation. About 50% of this water is wasted due to overwatering caused by inefficiencies in traditional irrigation methods and systems. Smart irrigation technology might just be the answer. Unlike traditional irrigation controllers that operate on a pre-set programmed schedule and timers, smart irrigation controllers monitor weather, soil conditions, evaporation and plant water use to automatically adjust the watering schedule to actual conditions of the site. For example, as outdoor temperatures increase or rainfall decreases, smart irrigation controllers consider on site-specific variables, such as humidity, soil moisture levels, temperature etc. to adjust the watering run times or schedules. In this paper, we propose a system which takes into account conditions like humidity and temperature and uses a two timer shift program where if the temperature is above the threshold value and humidity reading is below a certain level, it postpones the initial irrigation batch to the next shift which might be set to occur after like 10 hours thus saving a lot of resources as if it rained just a few hours after the initial shift, all that water as well as electricity is saved.
