Sensors Readings

[wpeeters 30]

And hereby the result of the test of the Ph probe signal split.
Remember, I have Ph injector pomp which also read Ph values. I want to split the signal from the cable so I can also read through 0-10V and Fibaro RGBW device and make warnings when Ph is too low or too high.

The test is starting at the red vertical line. If I split the signal and connect to second module (ph mv to 0-10V converter) the Ph value is increasing a little bit (8.82 to 9.38). The Ph value is decreasing again when I disconnect Ph probe from the second module. The high peak is the disconnect of the probe and switch from cheap to expensive Ph probe. Same behavior on this one and almost the same values.
Conclusion : I'll split the signal once my pool is up and running again in spring. I'll calibrate the probe while connected to only 1 output and calibrate again once more after splitting the signal.
Warning : This is very short term test. I have no idea what behavior can be on long term and what the impact is on the life time of the Ph probe.

Hi, Do you use the ph and orp probes that you linked from Aliexpress in the Zelia pod?

I read somewhere that they didnt fit the Zelia pod?

Hi and thank you all for an inspiring topic want to do this as well but am also investing to include the pressure gauge on the sand filter, anyone with experience of this?

With the pressure sensor i get reading of the pressure inside sand filter and when pressure rises above 0.9 Bar i get a notification to backwash my filter

yes @Forall, there is

Thanks must have missed that post and which one you use ?

[SmartHomeEddy 821]

Your welcome.
 

I new it was there because I have read it and I liked the solution, pressure rises when the filter needs a backwash.

Thank you

 

I bought the probe Holders from PoolPlanet

 

here is the link if you are interested

these probes were supposed to be connected to the Z3 Salt chlorinator but since it was waaayyyyyyy too small i have decided to use it for my DIY project .....

 

The probe holder is quite cheap and very very beautiful ...

 

..

 

I'm Thinking of making a list of all the hardware that is needed ( i think i have already ) so if anyone wants to build one it is quite easy .... as long as there is some basic electrical skills embeded in the brain

 

The other thing i was thinking is that if anyone knows a way to build a VD in order to have better control of this, can post it here so that other members can benefit from it

 

 

I am looking for the correct probes that fit in this probeholder.

Can you provide me with a link to the correct ph, temp and orb probe?

Hi @akatar

 

do you mean the sensors?

@SmartHomeEddy Thanks!

I was interested in your solution. Can you give advice on how to buy, what is your latest knowledge? Have you tried connecting it to the smart fibaro implant?

They could somehow be attached and inserted into the pool pipe. Some redukction or? It possible to insert other probes  like from aliexpress? Thanks
