How to Make a High Quality Water Level Indicator | 5 Level in a PCB
A water level indicator is a system that relays information back to a control panel to indicate whether a body of water has a high or low water level. Some water level indicators use a combination of probe sensors or float switches to sense water levels. “The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container. The purpose of a water level indicator is to gauge and manage water levels in a water tank. And this is my DIY one.

Components Needed:

5 pcs BC547 NPN Transistor
5 pcs 100 ohm resistor
5 pcs LED lights 5mm
Insulated wires
Soldering
9v input
