At times you just need a simple device that just works and this is one. This DIY kit indicates the level of water and sets an buzzer whenever it reaches a certain level. There are 4 levels and the buzzer can be triggered at any level you wish with the help of jumper.
How it works?
As seen the diagram above, the positive voltage(+9V to +12V) is always present at the bottom of the tank. The other wires for level 1, level 2, level 3 and level 4 are arranged as shown. You can use the water proof tape to strap these wires on the main wire that goes to the bottom. Check the pictures at the bottom, I had installed it at my home.
