Optical, mechanical, and capacitive sensors can all be used with reef-pi. I think mechanical float sensor makes the most sense unless there are other restrictions.
Here's how I understand the differences between them.
+ No moving parts to get jammed by snails or algae
- Water drops can stick to the sensor causing false readings
+ Can be mounted on the outside of the reservoir
- Somewhat difficult to get lined up exactly where you want it since the trigger point is somewhere in the sensor
+ 2 can be wired in series to provide fail safe shut off
+ Easy to identify switching point
- Snails and algae can cause the switch to stick
Will have a 20G long sump, maybe go with a mechanical float with an optical backup. So many things that I am working on but trying to collect things to have on hand so when I get to that point I can just continue along. I have one float already will need to figure out what else is needed to make it work.
