Congratulations to the ICStation team! They have developed this wonderful water level sensor module by great efforts.This module with small size and high cost-effective is easy to use.In this article, we will use the digital storage oscilloscope to show you how the output voltage change with the immersion depth.What’s more,we will show you an interesting actual application case.You will have a clear idea of how this module to realize the function of water level alarm.

This module is designed mainly for the DIY hobbyist and provide them a low-cost and easy-to-use water level detection scheme.The stability and durability of this module can not reach the industrial standard.But we use the high-quality PCB board to improve its stability and durability.If you just want to DIY for fun, this module will be a good choice.

Step 1: Diagram

<p>i just bought the same sensor and made it work. awesome!</p><p>now i need to find one that can be fully submerged in water. it doesn't seem like a PCB version would last long inside water. where would be a good place to look for a submergable version of this water sensor?</p>
Did you ever find a submerge lie version?
<p>Where can I get the code?</p><p>Also, I dont have a voltage mesure thingy (sorry for my word usage), how can i check if my sensor works?<br></p><p>Thanks a ton, I wish i can procced with the project.</p>
<p>Also, Does the R1 LED have to turn on?</p>
<p>After some experimentation, I've determined that this type of water sensor isn't useful as-is. The flat surface holds water, so the sensor really has two states: dry and &quot;has touched water some time in the last hour&quot;. Ok for a toy or educational implementation, but would need me to take a Dremmel tool to it to be useful in actually watching for water.</p>
<p>Also the connection diagram or a picture with more details of the cables and pins</p>
<p>Hello man, do you have the sketch from this project? i would like to use it and improve it adding more stuff . Thanks!. my email is diegoprado23@gmail.com </p>
