Water Level Sensor Circuit Diagram. Water level alarm circuit using level sensor the following circuit shows the water level circuit diagram. Before starting the design process of this circuit let s give you a brief explanation of the uln 2003 ic.
Uln 2003 ic belongs to the family of uln 200x series if ics. Here we have created 4 levels low medium high and full we can create alarms for more levels. For any electrically conductive liquid level measurement this single chip circuit is very compact and simple.
A water level sensor or liquid level detector is a very useful device for measuring or detecting a required level of water liquid or fluid in a tank pool well aquarium washing machines etc.
The circuit diagram is quite simple with only a few components but it can perform a great number of tasks as a monitor for the desired level of any fluid. This is the circuit diagram of a simple corrosion free water level indicator for home and industries. Water level sensor circuit diagram. Uln 2003 ic belongs to the family of uln 200x series if ics.
