For years I used Reefangel + to control my pumps and my ATO system. Reefangel has a 4 port air pressure based water level sensors. They are very idiot proof since they are just 1/2 inch pvc pipes providing the pressure information. In my case the sensors are in my ATO bottle (3 parallel connected water bottles), return pump sump section, tank to sump and middle sump. Return pump water level sensor starts the ATO activity and stops it when full, ATO water level checks the levels, when it is low it stops the ATO pump to make suction sounds and others sensors give me a sense of security. At one point I was using the tank to sump sensor to control my DC return pump to keep the tank level steady.
In the last earthquake in Bay Area, it seems like waves were over the rim, not only I found water on the floor but I noticed my RA+ is acting funny. I opened it up and found enough salt water around the ICs. I cleaned it up with electronics cleaner but it is still have issues. And I bought an Apex EL to replace it, just because they are my neighbors ( same town), not that it is helpful.
I don’t like any of Apex ATO solutions, I liked RA+ air pressure based water level sensors. I would like to be able use my existing sensors. Anyone tried to integrate them? I guess the sensors just give a level information within 0-5v. I am planning to check the output using an oscillator, but anyone tried that?
