14+ Water Level Circuit Diagram. Water level alarm using 555 timer. Double check all connections because playing with high voltage is danger.
Though there are many solutions to it like ball valves which automatically stop. In the circuit ultrasonic sensor module's trigger and echo pins are directly connected to pin 7 and 6 of arduino. Most the circuit only display the amount of water present in circuit, but this circuit will on and off the motor according to the level of water present in tank.
Initially there is no voltage applied to the base of.
14+ Water Level Circuit Diagram. Water level indicator and alarm using uln2003. The probes are arranged in such a way that they sense ¼th, 1/2, ¾th and even full levels as they are placed with equal spacing one. If you want to learn how to make a schematic and pcb then watch my tutorial. Each sensors float is suspended from above using an aluminium rod.
