WaterIT — Smart Irrigation and Plant Care System
Sahu Dec 13,2025
WaterIT is a smart plant watering and care system that I built to solve a problem I kept seeing around me: plants were either getting too much water or not enough, simply because people were guessing. At home and in school gardens, watering was usually done on a fixed schedule without checking soil condition, weather, or the type of plant. This often led to wasted water and unhealthy plants. I wanted to build something simple, affordable, and intelligent that could take decisions on its own and ...
