And by watering little water we can reduce the temps. For better controls we need to also monitor the temperature as soil temps above 35C are also harmful for plants. To solve this problem we can make a Internet connected device that controls he irrigation system. So that there is no over watering and all plants get the "required" amount of water. ![]() ![]() To solve that I planned to make a device that controls the irrigating system properly. almost 30% of irrigation water is wasted in over watering. There is overwatering (like a lot) at some plaes and completely dry (where vegetation dies) in some other. I have observed many a times that in some parks, water is not given properly to plants. To make the irrigation system in gardens, farms and backyards more smart and automatic. ![]()
