PRELIMINARY — PROPOSED VALUES. Values marked ‡ are proposed, industry-typical figures for this product class, provided so no specification is left blank. They are not measured and not final, and no value in this document is a certification claim. Engineering must confirm every ‡ value before this datasheet is released as final. See §12 for change control.
Figure FIG-001 — Sensorium™ Gateway, the ruggedized Connect layer of the Sensorium™ family.
1. At a glance
The Sensorium™ Gateway is the Connect module of the 5Tech Sensorium™ family: a ruggedized edge gateway that serves as the local hub for a site. It aggregates data from Sensorium™ BLE sensor nodes — Zone Awareness sensors and SmartBolts — over Bluetooth Low Energy, applies edge processing, and transmits results to the 5Tech Platform by MQTT over TLS on Wi-Fi or wired Ethernet, with LTE cellular as an ordered option. It is built for industrial and outdoor sites where connectivity can be intermittent.
| Product | Sensorium™ Gateway (Universal IoT Gateway) |
| Family / role | Sensorium™ · Connect |
| Function | BLE sensor aggregation, edge processing, secure MQTT/TLS uplink to the 5Tech Platform |
| Uplink | Wi-Fi (2.4/5 GHz) · Gigabit Ethernet · LTE cellular option |
| Downlink (Sense) | Bluetooth Low Energy 5.x, up to 50‡ Sensorium™ nodes |
| Enclosure | Die-cast aluminium body with non-metallic antenna cap; IP65‡ (IEC 60529) |

Key features
- Local BLE 5.x aggregation hub for up to 50‡ Sensorium™ Zone Awareness and SmartBolt nodes.
- Wi-Fi and Gigabit Ethernet uplink with MQTT over TLS 1.2/1.3‡ to the 5Tech Platform; LTE Cat-4‡ cellular as an ordered option.
- Edge processing: filter, buffer, and pre-process data before uplink; ≥ 72 h‡ local store-and-forward buffer so data survives connectivity gaps.
- Ruggedized IP65‡ die-cast aluminium enclosure with a non-metallic antenna cap so the internal BLE antenna radiates through the housing.
- Redundant DC power inputs (A/B) with reverse-polarity and surge protection for continuity.
- Authenticated, encrypted MQTT/TLS uplink with per-device X.509 identity‡.
Typical applications
- Site connectivity over Wi-Fi or Ethernet, with a cellular option where fixed networks are limited.
- Aggregating BLE safety and asset-monitoring sensors on a single site uplink.
- Edge buffering so no data is lost during connectivity gaps.
2. System context
The Gateway is the bridge between Sense (BLE sensor nodes) and Decide (the 5Tech Platform). Sensor data flows up through the Gateway to the Platform; monitoring, automation rules, and configuration flow back down.
Figure FIG-002 — Sense → Connect → Decide. The Gateway is the Connect layer.
- Sense — Sensorium™ Zone Awareness (proximity / zone sensing) and SmartBolt (load / vibration sensing) BLE nodes.
- Connect — the Sensorium™ Gateway aggregates and pre-processes their data over BLE.
- Decide — the 5Tech Platform (Monitoring · Automation · AI assistance) turns data into monitoring, alerts, and recommendations.
- Solutions — Fleet Management and Construction Sites Monitoring are built on this chain.
3. Functional overview
Figure FIG-003 — Functional blocks: field I/O, edge compute, network uplink (Wi-Fi/Ethernet, cellular option), switching, security, and redundant power.
The Gateway combines four functional groups:
- Field I/O — a BLE 5.x central that aggregates Sensorium™ sensor nodes, plus an isolated RS-485 port and digital I/O for third-party sensors and PLCs.
- Edge compute — buffers, filters, and pre-processes data at the edge; runs local logic so the site keeps functioning through connectivity gaps (≥ 72 h‡ store-and-forward).
- Connectivity — Wi-Fi and wired Gigabit Ethernet networking, with an LTE cellular modem as an ordered option, keeping the MQTT/TLS uplink to the 5Tech Platform available.
- Power & integrity — redundant DC power conditioning, reverse-polarity/surge protection, and a hardware watchdog for continuity.
Data path: BLE sensor nodes → field I/O → edge compute (buffer/filter) → MQTT/TLS uplink → 5Tech Platform. Control and configuration flow back over the same secured channel.
4. Ordering information
Order codes below are the proposed scheme; the base identifier and suffixes are ‡ pending confirmation. Configure = base + uplink option + I/O option.
| Order code | Configuration | Notes |
|---|---|---|
SEN-GW-100‡ |
Base gateway | Wi-Fi + 2× GbE, BLE 5.x, RS-485, 2 DI / 2 DO |
SEN-GW-100-C‡ |
Cellular variant | Base + factory-fitted LTE Cat-4‡ modem |
SEN-GW-100-X‡ |
Extended-I/O variant | Base + additional isolated RS-485 / DI-DO |
Accessories and spares: see §10.
5. Mechanical specifications
Figure FIG-004 — Front and side elevations with mounting pattern (mm). Values ‡ proposed.
| Parameter | Value | Condition / note |
|---|---|---|
| Dimensions (W × H × D) | 180 × 130 × 60 mm‡ | Enclosure only, excluding antennas/connectors |
| Weight | 1.1 kg‡ | Base configuration, no antennas |
| Mounting | DIN rail (35 mm) or wall bracket‡ | Vibration-qualified per §8; see §10 |
| Enclosure body | Die-cast aluminium, powder-coated graphite‡ | External convection fins; no vents (fanless) |
| Antenna cap | Polycarbonate (RF-transparent)‡ | Houses the internal BLE antenna |
| Ingress protection | IP65‡ (IEC 60529) | See §8 |
The internal BLE antenna radiates through the non-metallic polycarbonate cap; Wi-Fi and cellular use external SMA antennas (§7). This resolves the metal-enclosure / internal-antenna conflict.

11. Monitored signals & alert behaviour (illustrative)
Figure FIG-007 — Illustrative — a monitored signal crossing its configured alert threshold (or an abnormal trend) raises an alert; a person decides on any action. Representative behaviour, not measured data.
The Gateway reports its own health signals — uplink status, sensor-node connectivity, and power health — to the 5Tech Platform; when a signal crosses a configured threshold or shows an abnormal trend, the Platform raises an alert and a person decides on any action. Thresholds are configured per deployment.
| Signal | Example alert trigger‡ | Response |
|---|---|---|
| Platform uplink (MQTT/TLS) | Uplink lost > 60 s‡ | Alert + notify (person decides) |
| BLE sensor-node link | A paired node stops reporting beyond 3× its interval‡ | Alert + notify (person decides) |
| Redundant DC power input | One of inputs A/B drops below 9 V‡ | Alert + notify (person decides) |
Illustrative — representative, not measured; trigger values ‡ proposed and configurable.
