Led is used to provide a visual indication of the required level detection. Any liquid it will activate the led when the two probes shown in the circuit will detect liquid. We can design the water level indicator circuit using uln2003 ic as the main component.
Here we have created 4 levels low medium high and full we can create alarms for more levels.
The circuit is based on 5 transistor switches. Before starting the design process of this circuit let s give you a brief explanation of the uln 2003 ic. This is the circuit diagram of a simple corrosion free water level indicator for home and industries. Any liquid it will activate the led when the two probes shown in the circuit will detect liquid.
