Introduction: How to Make Simple Water Level Indicator

Picture of How to Make Simple Water Level Indicator

Do you want to make water level indicator for easy! Try this. This simple water level indicator no needs Transistor or IC. I Make this for another project! this can use for Water bottle, Water tank, or another things you want to use this

Step 1: The Schematic

Picture of The Schematic

Follow the schematic. You can use breadboard, PCB, or just solder it.

Step 2: Make the Case

Picture of Make the Case

For better look, I make The case from mini bottle. and I glue heatsink under the bottle for better stand.

Step 3: Full Instructions and Testing Video

Thanks For look my work. I Hope this work for you. Because I made this 100% work.

thats a cool and simple build, yo.

The resistor isn't even needed !

balsuryana (author)rafununu2016-02-25

Yes but I only keep the LED does not burn

rafununu (author)balsuryana2016-02-25

But they won't with the resistance of water. Anyway a 33ohm is too small to protect the leds.

balsuryana (author)rafununu2016-02-25

In the scematic image, I write 33ohm or bigger.

Use an appropriate resistor for LED and best result.

Thanks for your suggestion

:)

Using a transistor would make it more sensitive

true and the LED would more likely burn at a constant bright level. Yet, this is a smart idea

BeachsideHank (author)2016-02-24

It is as you say, simple and cheap, no real need for heightened sensitivity since water will conduct enough to illuminate the appropriate LED.
