Water Level Detector | Water Level Sensitive Circuit for Projects

This is a water sensitive circuit diagram.I suppose this circuit will give you lots of benefits .I have modified this circuit up to some extent and have added to our water pump moter (230 v).

Numeric Water Level Indicator Circuit

The numeric water level indicator circuit works off 5V regulated power supply. It is built around priority encoder IC 74HC147 (IC1), BCD-to-7-segment decoder IC CD4511 (IC2), 7-segment display LTS543 (DIS1) and a few discrete components.
