This clever tutorial shows how to create a circuit that indicates how much water is in a container using a built-in alarm system, stopping any possible overflows.

By using blue LED lights as a visual indicator this homemade device signifies whether the water level is low, medium, high or full.

Wrapping the platforms in aluminum foil allows the circuit to be completed when the water level increases meaning the LED lights switch on and when full the alarm goes off.

Such a device is useful when it is not possible to see the water level in a container.

How to make a water level indicator is a science project to save water from overflowing.

A water level indicator is used to show the level of water in an overhead tank. This keeps the user informed about the water level at all times and avoids the situation of water running out when it is most needed. There are many videos on youtube But this one is unique because this water level indicator circuit also has an alarm feature. It not only indicates the amount of water present in the overhead tank but also gives an alarm when the tank is full.
