I find the pro/con for this solution in an industrial environment interesting:
- adding yet another power/data line for a sensor is expensive, possibly requiring equipment to be shutdown, new mounting points to be drilled, etc.
- trying to find an accessible current carrying wire that isn't further enclosed in a ferrous enclosure that would block RF.
It reminds me of the time my boss suggested using inductive power for a camera in a dairy barn. It's a wet and difficult environment where urine, salt, water, temperature swings were common. How were we going to get the power to the inductive coil? Ah, yeah.
