This soldering kit makes it possible to check and display the fill level of water containers such as rain barrels, aquariums, fountains, water tanks and much more. The coloured LEDs on the board signal the different fill levels.
If necessary, the board also controls an external relay, which switches on a pump, for example. A standard 9 V battery (not included) serves as the power supply.
