Introduction: HOW TO MAKE a WATER TANK ALARM

Connect all negative terminals of leds with each other like shown in the image and connect the resistor also.

Step 1:

Connect all negative terminals of leds with each other like shown in the image and connect the resistor also.

Step 2:

Connect the negative end of the battery with the resistor.

Step 3:

Connect a wire with the possitive end of the battery connector and leave the wire touching in the bottom of the tank so that the circuit will become complete.

Step 4:

Connect a wire with the possitive end of the battery connector and leave the wire touching in the bottom of the tank so that the circuit will become complete.

    or.... you only consider the light indicator panel....

    or... you're hopping to get full voltage/current through the water to lit the led's?

    I think you should explain a little better what is your purpose! Just to clarify please!

    Thank you!

    I am not certain what this monitors, what the circuit looks like, or what kind of sensor it uses to give an alarm. What is this? How do I use it? What does it do for me? Why do I need it? How have people done what this does until now? Thank you.
