Off the shelf way to send data over Dc power cables?
Jackster:
It is probably over complicating the design but I would like to send data, something like I2C, over a DC power cable.
My needs is to send a sensor output to a brain box but I would rather not use wireless, and a data cable is out of the question.
So I am hoping there os something that is off the shelf that allows one to do this with ease.
I only need to send data over 2m.
And the power line is only ever powered by batteries. Looking at 5-30v range.
Any ideas?
Is this even possible?
Thank you!
Edit
Looks like I used to basic of search terms on Google. Finding ICs now.
Mr.B:
What is the sensor?
If you are only wanting temperature, the DS18B20 only needs two wires to operate.
It sends its data over the power supply line using a protocol invented by Dallas, now Maxum.
Multiple implementation librarys exist for multiple MCUs.
Jackster:
Little bit worried about this sort of thing giving off signals.
Will have wireless mic equipment near where this is going.

Not sure on the sensor atm.
Still looking to find what I need.
It will be a level sensor though. Hopefully one with built in compensation for moving around.
Can't have 8t giving off incorrect readings if one is moving the sensor around left and right.

What's the required bandwidth/speed ?

Erm, 2m, whats stopping you just adding more wires/cores?
Simplex/ half/full duplex?
Off-the-shelf solutions: Bluetooth/RF data modules? Infra red modules.
