Any issues with the camper installations? I’m concerned now with installation on my four tanks.
For what it’s worth, my design includes 8266 module which is WiFi which allows me wireless connectivity to status panel I designed or to phone or tablet.
I may post the approach here if I decide the algae (or other material)film problem doesn’t prevent me from completing the installation.

Interesting: I can only see algae being a problem if you mount the copper strips on the inside. In my application here the copper tape/sensors are on the outside.
