I thought it might be a fun project to build a reverse osmosis controller that would work with the RA. I am not sure if an Uno would be good for this or not or using some of the available RA modules.

Here is the concept. Please keep in mind some of this is useful but somewhat overboard. its just something I thought would be fun to build.

Monitor multible tds readings
incoming
post pre filters
post membranes(I run dual so I would want to keep an eye on both)

Monitor flow with meter sensors
incoming
drain
outgoing
between any given 2 sensors you should be able to do the math to give you the gallons of the 3rd sensor but its overboard anyway

monitor pressure
monitor water pressure of incomoning
post filters
strorage tank

monior leaks
the RA leak detector would work perfect. my ro unit is in the basement so I dont always look at it.

Control
booster pump
uv
system shut off
scheduled membrane flush
RA buzzer
Notifications

Any thoughts? :D
