At your site
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
- Compare site distance, cable installation cost and 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.

Hardware used in the comparison
Product-family photos; the model and enclosure may vary.
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

FAQ
How do I choose between the two options?
RS485 fits these conditions: Devices are inside one cabinet or nearby panels. LoRaWAN fits these conditions: Sensors are far apart or outdoors. SunGene can shortlist hardware after reviewing the site and integration details.
Can SunGene quote both options?
Yes. Send the site layout, measurements, available network and quantity. We can compare equipment and accessories for both options.
Does this comparison include pricing or guaranteed certification?
No. Pricing and certification depend on the selected hardware configuration and target country, so they are confirmed during quotation.
Can we test an option before a wider rollout?
Ask for a sample or pilot configuration. Agree the interfaces, power, mounting and receiving system, then compare local readings with the received data. Confirm model-specific documents and any required approvals before ordering.
