remote sensors - wich (wired) connection is better?

Using Arduino Project Guidance
15

RS485 Cable spec;-
Shielded: Yes
Impedance: 100-130 ohms
Distributed capacitance: <100 pF/m
Wire: AWG 18

Cat 5/6 Cable spec;-
Shielded:STP, ScTP, UTP
Impedance: 85-115 ohms
Distributed capacitance: <= 52 pf/m
Wire: 24–26 AWG/Cat5, 22–24 AWG/Cat6

2 catches for using Cat 5/6 Cable sub RS485 Cable;-

  1. Impedance, It could be fine tune the transceiver resistor to keep match.
  2. Only STP Shielded cable is compatible, order that type cable only.
