@pjblink - what are the components you have built in there? I see the Arduino Nano and a relay - are they all attached to a board? Is there a radio in there, too? I clicked on the (old) link above for Mini RBoard, but I get a gateway error when going to the page to purchase...

@Nca78 have you been using the Rain Water Level Sensor modules for a while? Can you run more than one on a pro mini? I was thinking, since they are small, that I could use a few at different levels to have different actions. I saw a water level eTape, but it is a bit expensive (haven't seen a Chinese knockoff yet). Or I suppose I could combine the sensor for initial water detection, then the ultra sonic to figure out depth.
