Using this schematic electronic project can be designed a very simple water level indicator electronic circuit that uses a 7-segment display to indicate the water level (low, half and full)in the tank. This water level indicator electronic circuit shows the water level by displaying L, H and F for low, half and full, respectively. This water level
water level indicator using 7 segment display - schematic

indicator electronic circuit is based on the 7408 quad two inputs and gates IC (that contains four input independent gates) and a 7404 hex inverting gates IC. The circuit uses five level sensors to sense the different water levels ( one for common GND, one for low, one for high one for half and one for overflow ).
