In the water level sensor schematic, the common probes connecting the underground tank and the overhead tank to +9V supply are marked ‘C’. The other probe in underground tank, which is slightly above ...

In the loop () we check to see if the water level has reached any sensor and if so then turn an the corresponding led. We also use the LCD to display HIGH if the water has reached the highest poing, ...

Circuit Fig. 3 shows the circuit diagram of the automatic water level indicator cum controller. It is built around an Arduino Uno board (MOD1), three LEDs, a 5V SPDT relay, and other components. First ...

As the top sensor goes low (water above level C), the CLR signal is activated and the output of the flipflop is low. This allows Q1 to turn on and activate a triac or relay for the pump.
