In the field of agriculture or even in the home plant it is necessary to monitor the water level of the plant,its moisture contents and accordingly pour water to them.So this is some times ignored when dont pay attention towards the plant.So in vigyan ashram we developed a small kind of device that will sense the water contents of the plant and will do corresponding action.
In this case when we insert the probes in to the plants base and if there is no water then the corresponding indications in the form of LED and BUZZER are provided and corresponding action can taken.
