Buyer scenario
Wired sensors are stable and easy to power when cable exists. Wireless sensors reduce installation work but need network, battery and payload planning.
Decision table
Installation
- Wired sensors
- Cable routing and panel work
- Wireless sensors
- Radio coverage and mounting work
- Guidance
- The cheaper sensor is not always the cheaper installation.
Power
- Wired sensors
- Usually powered by cabinet or loop
- Wireless sensors
- Battery, solar or local power options
- Guidance
- Battery maintenance must be part of the plan.
Data reliability
- Wired sensors
- Predictable when wiring is protected
- Wireless sensors
- Depends on signal strength and reporting interval
- Guidance
- Wireless needs a coverage check.
Typical Hardware Architecture
Final system design, software integration, PLC/SCADA programming and site installation are handled by the customer or their system integrator.
RTU / Data Logger
RS485 to Ethernet Gateway / Serial Server
Customer system
Customer's SCADA / Cloud / PLC System

Choose Wired sensors when
- The site already has cable trays or cabinets
- High polling frequency is required
- Maintenance teams prefer fixed wiring
Choose Wireless sensors when
- Cabling cost is high or disruptive
- Sensors are outdoors or spread out
- Low-frequency telemetry is enough
Information needed for quotation
- Sensor locations and distances
- Available cable path or radio coverage
- Power source at each point
- Reporting interval and alarm urgency
