It could technically be used but you would have to code an arduino in between or run thru an ADC. But this may prove difficult because the code would have to be compatible with the reef pi ph driver. Or you would have to write ypur own driver.
It would be much easier to get a compatible ph board. Reef pi can use one of three boards.
1. The EZO board
2. The reef-pi ph board designed by @Roberto_b
3. The ph board that is a redesign of the roberto_b board using easier and cheaper to get parts. @Michael Lane did the redesign and sells them on his tindie site

The choice for Addd-On boards is becoming quite vast now. There are definitely options for all levels of bumblefartery

Thanks for the mention, shipping my first wave of them this week!
. Thats so cool. Keep up the good work.
@Ranjib first of all thank you for this amazing project!
there's a way to run the ATO pump for n seconds and after that the system goes into a "failsafe" status? I'm trying with the alert but something doesn't work in right way. The first time I have the right trigger but after that I cannot make it work again.
Second question is about setting up the email alert. I've created a dedidacted gmail address to send email from reef-pi, generated the application password but I cannot send the test email... What I'm doing wrong?
Thank you very much!
Best regards

Thank you very much! Another question how do I set the LCD screen? does it only work with the original Rpi LCD?
rpi doens't have any analog to digital capabilities, but ADS1115 seems to be a common module. It should be relatively straight-forward to add a driver for this ADC to reef-pi. I have a few other things I'm looking at, but if someone has a bit of programming experience, I'd be happy to offer advice on implementing a driver for this chip.
The pumps don't have a good solution yet, but ATO, dosing, pH, and outlets are pretty much solved. I have some wiring diagrams examples, but feel free to tag me if you start a dedicated build thread. It's easy for individual build questions to get lost in this main thread.
This is HS100 (you suggested HS110).
reef-pi's built in display controls are only for . official touch screen.

How much does it cost ? Ezo itself is 40$ excluding voltage isolated. With voltage isolator and BNC connector the circuit itself is 80$ . Probe extra. The reef-pi ph probe is 40$ including adc, voltage isolator and bnc port.
I think it was because I had 5v regulator on mine and not on Atlas.
affordability, opensource and applicability are some of the key pillars for reef-pi. The EC/Salinity probe was left out because it violates all three of these. I have a spare tentacle board that I am planning to use for EC probe support at some point in time, but i see that less important compared to stepper drivers, light acclimation, wave maker support, startup/shutdown macro and many other awesome features that reef-pi still dont have :-(Yeah Atlas is very expensive. I'm pricing it the same as others at $40 but have room to move, in campaign its $25 extra. It has microcontroller, op-amp, ADM3260 isolator and a good 5v regulator, head to head with Atlas in 7.0 using same probe mine is more stable.

I need to make a listing for the Reef-pi version but same thing without all the extras. Reef-pi version will also be shorter and no USB's.
One day I'm hoping to create a driver for EZO EC or convince one of you, I understand why you haven't. I already have an EC board in my box but still need to get equipment to compare against so on shelf for now, it will work like EZO but only $40 max instead of $100. I will give all files so you have, I know you like readily available. A lot of users I have won't convert to Reef-pi until it has salinity monitoring.
