Bridging to remote location, only 2 conductors available.
-
Hi,
Am very new to this and am having an issue reaching an underground cistern via RF (have tried various antenna configs etc).
Unfortunately, I only have 2 unused conductors from my house into that cistern,
Does anyone have an idea how I can best get the data from a sr-04 ultrasound distance meter into my Mysensors network using only those 2 conductors (power is also available at the cistern)?
Many thanks in advance,
B

You would probably need a common ground also.

you could probably use rs485 (isolated) for this..
