Is there anyone who has a library part for an electrical conductivity (EC) probe? Because I’ve been searching but only found pH, TDS, and other sensors.

Not enough information to do anything with here. We would need a web site for whatever it is that you want which contains the physical dimensions of the device and the connection information to see if there is an existing part or to make a part (if possible) if there is not. Filling in the template which you appear to have ignored in this category would be a good start.

A google search of the form “fritzing part atlas EZO-EC” says neither appears to exist at present (there are other Atlas parts around both on the net and it core parts, but not apparently this one.). Both can be made but I am extremely busy right now and won’t have time. @RAPTOR7762 can you make these?

In Fritzing, there is already a library for the circuit modules; perhaps if a universal probe could be made so it can be connected to the modules, it would be very helpful.

</div>

You would need to provide a link to the .fzpz file for the module (as I didn’t find it in the google search) to see if the probe has connections (which is not likely.) Otherwise a jpeg image of the probe can be added as an image in breadboard and “connected” to the module to provide a visual which will have no connections in schematic.

</div>

Or can I use a potentiometer as an input to the module so that I don’t have to worry about the probe?

</div>

That will work as well. I see the part is in the Atlas bin of core parts but isn’t tagged as EC so doesn’t appear in the google search. It does have connections for the probe so either a probe part (which I don’t have to to create!) or a pot should do you.

Thank you for answering my doubts about that; you’ve been very helpful.

This part should do for the EC\_EZO interface board. I have not done the probe, it may be best to use an image in breadboard for the probe depending on what you want to do. In any case this is all I have time for right now.

Appreciate it, thanks for the design

@Sunnu\_Fadli Actually i think u need a purple carrier board (forgot what it’s called) But it’s needed to connect the probe. So do u need that part

Yes, if you don’t mind
