The water level indicator circuit uses a 7 segment display to indicate the water level (low, medium and full) in the tank. The water level in the electronic indicator circuit is based on the 7408 four-door, two inputs of IC (which contains four independent gates) and IC 7404 hex inverting gates.
When the tank is filled with a buzzer used to alert water overflows the tank. The water level in the electronic display circuit displays the water level, showing L, H and F for low, medium and full, respectively.
The circuit uses five level sensors to detect different water levels (one for common GND, one low, one for a high half and an overflow). A high voltage on the input pin of the door no, low voltage outputs. Low voltage at the input pin of the door does not, generates a high voltage.
