Water plays an indispensable role in human lives as people cannot survive without it; moreover, water is very essential in agriculture for producing quality grains. Henceforth, it is highly required to develop a water monitoring system (WMS) to avoid water waste. The water level in the tank is shown by WMS using LED sensors. LED sensors are installed at three levels: LED 1 in the lower level of the water tank, LED 2 in the middle of the water tank, and LED 3 in the upper level of the water tank. Several devices, including mobile phones, laptop computers, and other devices save all sensor data in the cloud. This article mainly explores the efficient ways to decrease water waste in the cloud by utilizing WMA.
