I have a battery and a 5V active buzzer. Putting the end of circuits (just raw wire) in the bucket full of the tap water is not completing the circuit. The buzzer, battery, and circuit are fine since when I just connect the battery and buzzer, it gets completed, and the buzzer starts buzzing.
Wire: 0.55mm copper wire Battery: 3 x SR44 1.55V 190mAh = ~4.5V Buzzer: 5V Active Buzzer
I have a use of this project. I have to check if water is coming out of another end of pipe. I also tried to put the wires at the end of a pipe when water was flowing through, and the circuit was not complete.
I am not sure here. Should I change the wires or increase the battery (by adding a few more SR44 cell)?
I am just a hobbyist and do not know many peculiar details. I would need your help to get this circuit working when water flows. Thanks.
