I have seen some discussions on creating some DIY leak detector boards and using them on the Apex BoB but can this also be done with an FMM module? The optical sensors are not too expensive but $30 for a box to detect water seems a little high. I have a BoB but it is full and picked up a second FMM just trying to figure out the best way to add 2 floor sensors and 2 water level sensors. The FMM is expecting 4 wires vs. 2 from the pics I have seen.
If going with Apex equipment is the best way, I can do that too but a little DIY feels good form time to time.
Thanks
