Hi!
I started my aquarium system managed with Ferduino. Yestarday i prepared the water and tomorrow i'm going to buy the rocks.
Unfortunately i'm still in troubles for 2 topics.
I performed calibration for all the probes the readings are absolutely not stable. I know that it is beacause of the fact that
probes are not isolated, ad Fernando explained. I tried to contact Chris in order to buy the isolation module but he is
too busy and till now he wasn't able to help me. anyway, this is a serious issue: i bought circuits and probes and i must have them
working, obviously. Moreover when i will use the calcium reactor the probes will be absolutely mandatory.
The other issue is with temperature sensors. I have the standard 3 probes connected in parasite mode with Ferduino with the
proper jack. At the beginning everything is fine. the dedicated page found the sensors, i can match with one is for water, for heatsink
and for ambient temperature. After a couple of hours the readings drop to -127°C and Ferduino is not able to find the probes
any more. if I deplug 2 specific probes and i leave the heatsink one connected, Ferduino find it, and it works in each connectors, no differences.
If I connect any other probes in any other position the system is not able to find any probes, neither the one that has been working previously.
If i leave connected only the working probe and i wait several hours, SOMETIMES if i connect a second probes it works, but the issue
pops out again after some hours.
I really need at least water temperature and heatsink temperature...
When i'm in the single sensor working condition and i upload the test code for temperature sensors that sensor obviously works well.
But if i connect a second sensor also the test code says "parasite power is OFF".
Any idea?
thank you so much
