Arduino Liquid Sensor Example Code and Schematic

How to read water level in a container using the Arduino development board and the eTape capacitive liquid level sensor. The eTape liquid level sensor changes resistance with the water level, using a voltage divider circuit the Arduino can read this change in resistance as a change in voltage and output the value in the serial monitor window.

Interesting, I might use this for a rain gauge. Thanks for the video.

There is a block in LabVIEW called "Elapsed Time" that outputs a boolean every time a specified amount of time has passed, in your case every hour. You could connect the boolean output of this block to a case block and put the Arduino voltage reading block inside.

can you tell me what arduino code did you use?

Hello, what exactly is your arduino code reading in? Are these resistance values?

Hi, did you buy the one without the case

Im trying to sample a voltage coming from a solar panel and automatically write the average of the sampled voltage to a spreadsheet every hour using arduino and labview. Im already using arduino labview to control the solar panel using 2 stepper motors but cant figure out how to modify the arduino continuous sampling vi to suit my needs any a video showing sampling with the arduino would be much appreciated.

What arduino code and what is your circuit. Can you show it well?
