Hardware
The gateway and sensor vendor is not decided. This page describes roles, not a brand. Hardware is quoted with the pilot after the survey, and this page has no price list.
Modbus RTU and RS485. A certified 4G/LTE gateway with Ethernet, RS232, RS485 and configurable I/O. It polls Modbus RTU devices and forwards readings over HTTPS or MQTT. Dual SIM covers operator failover. Use one at each process area that has serial meters or transmitters. Analog 4–20 mA signals come in through a Modbus RTU input module when the gateway input is a voltage input. The vendor is chosen at the survey.
Ethernet, Modbus TCP and LTE. A multi-vendor router with Ethernet and dual SIM. Use it at the main switchboard or control room where PLCs, VFDs or meters speak Modbus TCP, or where the factory LAN needs a managed uplink. LoRaWAN sensors can join the same platform later by publishing MQTT.
| Category | Examples |
|---|---|
| Climate | Temperature, relative humidity, CO₂ |
| Process | Process temperature, pressure, flow, level |
| Machine | Vibration, current, run contact, running hours |
| Energy and utilities | kW and kWh meters, steam pressure, water volume |
| Quality and mass | Moisture, weight, count |
| Safety contacts | Door, leak. Not a worker-tracking product. |
Any device that can speak Modbus, MQTT or HTTP can feed the same platform. LoRaWAN is compatible later, by publishing MQTT, and it is not the path we lead with.
