Buyer scenario
RS485 is strong for short wired runs and predictable polling. LoRaWAN is better when low-power sensors are spread across a wider site and cabling is expensive.
Decision table
Site layout
- RS485
- Best for cabinets, pump rooms and short cable trays
- LoRaWAN
- Best for tanks, farms and distributed outdoor points
- Guidance
- Start from distance and cabling cost, not only device price.
Power
- RS485
- Usually mains or cabinet powered
- LoRaWAN
- Often battery or solar assisted
- Guidance
- Low-power reporting favors LoRaWAN when intervals are acceptable.
Integration
- RS485
- Direct Modbus RTU polling
- LoRaWAN
- Payload decoder and network server needed
- Guidance
- RS485 is simpler for PLC/SCADA; LoRaWAN needs payload planning.

Choose RS485 when
- Devices are inside one cabinet or nearby panels
- A PLC, RTU or gateway already polls Modbus RTU
- Power and cable routing are available
Choose LoRaWAN when
- Sensors are far apart or outdoors
- Battery life matters more than high-frequency polling
- A LoRaWAN gateway can cover multiple points
Information needed for quotation
- Distance between sensors and gateway
- Power source at each point
- Required reporting interval
- Target country and LoRaWAN band
