Hello everyone ,
The presentation attached below is regarding application of IoT in water level controllers .I personally feel that checking water level in over head tank in house apartments and switching ON/OFF of the pump in order to fill the tank manually is a very tedious job . For this the person has to be present in the house in order to avoid drying of the tanks .Using IoT this problem can be solved as the device automatically checks the water level and fills accordingly .It even sends alert to the owner when there is any issue in the tank.
