Salinity Probe

[ucez]

I added relay expansion, power control expansion, and salinity expansion. Having 2 issues 1) salinity probe calibration stability and 2) both the salinity probe and ph probe seem to be oscillating between on/off same period, same length of time...Trying to figure out #2 before sorting out #1. If you look at web chart it's really obvious. File is attached.

Any ideas?

[binder]

have you tried isolating the expansion modules? like just add 1 at a time and check how it does. so remove the extras and just put the salinity probe in and see if everything still oscillates the same.

A new pattern has emerged, salinity still oscillating, but pH is now off (reading 1). I disconnected all the expansions, but pH is still not working.

[ucez]

I tried going back to original set up and old code. No luck, pH reading 1. Tried different pH probe as well.

[ucez]

Saga continues, salinity oscillating, pH not working at all. Maybe I have the connections wrong. Here's what I've got...

RA to main relay
main relay to expansion hub
expansion hub to relay box 1
expansion hub to power control expansion
expansion hub to salinity expansion
The power control expansion power is from the main relay
The salinity expansion power is from the power control expansion.

Below is my code.

Is there a way to "reset" the RA to start fresh? Note I already tried removing all the new expansions and loading the old code. pH was still dead...

[binder]

to reset to a fresh start, inside the arduino app, there is a restore preloaded code option that will do just that.

i would also suggest trying to not have your expansion power devices plugged into the ra, just in case there is some sort of interference. so plug your salinity module into the wall or another power strip (this is what i do).
now i have had some intermittent issues with my salinity probe, so if you haven’t calibrated it, you could try that again.

as for the ph probe, look at the probe and make sure it’s not damaged or broken. probes wear out over time and need to be recalibrated or replaced (i’m sure you already knew that but i’m just stating it again).

that’s all the suggestions that i have. maybe someone else has more ideas.

It's definitely not the probe, tried 3, all read 1.00. I restored the preloaded code and plugged the salinity expansion into a power strip, no change. pH is still reading 1.00.

[ucez]

Plugging the expansions into separate power strip seems have stabilized the readings. pH slowly climbed from 1 to 5.1, still off, but at least it's reading...will try to recalibrate and see what happens.

[binder]

that is interesting to know.

[ucez]

pH has definitely stabilized, so that's good. However, salinity is still variable, bounces from 26 - 36. Is this typical?
