FDC 1004 Capacitance Water Level Sensor

Partly project / partly code related issues. I bought one these chips cap sensor chips here:

https://www.protocentral.com/gasliquid/1082-fdc1004-capacitance-converter-breakout-board-0642078949616.html

It works as described / setup in the example (you can find the example code at the Github link from the link above...bottom of page)

In the example, it uses channel 1 of the ic (in the code it's actually CHANNEL 0) to read the capacitance of the water. It reads by using two conductive strips running parallel along the entire (outside) length of a container.

My question is HOW DO I SETUP A SECOND , REFERENCE CHANNEL TO COMPARE AGAINST? Basically I want add another, shorter pair of conductive strips at a fixed length to compare against the longer leads to help dispense accurate water amounts. I looked at the code (which comunicates to the Arduino via i2c) but setting up a second channel is WAY beyond my coding skills. Any suggestions on how to tackle this would be great. This chip seems an absolutely amazing little thing...if I can utilize its full potential. Please and thank you.

If you want someone to code or do research for you, you should request that a mod move this to the "Gigs and Collaborations" forum.

If you make an attempt yourself, you can post the code here and get help.

It might be useful to also say a bit more about the project - A lot of dispensing systems use weight , which is easier to deal with .

OK Shannon...I will take your advice to move this to a more appropriate arena - thank you
