I’m looking for a serial technology to implement a bi-directional serial bus that could link sensors and microcontrollers over a distance to about 50m. I2C would be fine if it had the range.
My requirements are:
- 50m range
- all components can transmit & receive
- wiring: ground+2 wires or ground+4 wires
- unrestricted network topology (Y-splits etc.)
- implementable with Arduino
- sensor & controller ICs available
Can anyone help?
