Overview
In the Tobe Twin platform, a Device refers to any hardware unit deployed on site to capture location, operational metrics, environmental telemetry, or movement data.
Devices range from hardwired 12V vehicle trackers and OBD-II plug-and-play dongles to long-life battery sensors and wearable Bluetooth Low Energy (BLE) tags.
Device Categories
SensGrid supports four primary hardware categories:
Wired Devices (e.g., Arrow / Dart3 BLE)
Permanently wired into vehicle or machine 12V/24V power systems.
Captures high-frequency GPS tracking, true ignition-based run hours, harsh driving events, and acts as a mobile BLE gateway.
OBD-II Devices (e.g., Bolt / Bolt2)
Plug-and-play trackers inserted directly into light vehicle OBD-II diagnostic ports.
Captures GPS location, virtual run hours, vibration run state, and accelerometer events without requiring custom wiring.
Battery-Powered Devices (e.g., Barra Fusion, Manta Fusion, Remora, Hawk)
Autonomous, ruggedized trackers powered by long-life lithium batteries.
Deployed on non-powered assets like site sheds, gang boxes, toilets, trailers, and remote monitoring points.
BLE Tags (e.g., Minew Helmet Tags, Eddystone Driver Tags)
Compact, low-cost Bluetooth beacons attached to tools, equipment, or workforce PPE (safety helmets, wristbands, ID cards).
Relays spatial location automatically whenever brought within range (up to 50 meters) of a BLE gateway device.
Telemetry & Analytics Capabilities
Depending on hardware specifications, devices capture raw sensor telemetry which Tobe Twin translates into operational insights:
Data Type | Raw Sensor Telemetry | Derived Platform Analytics |
Location & Movement | GPS Coordinates, 3-Axis Accelerometer | Live Map Position, Travel History, Speeding, Harsh Acceleration, Harsh Braking, Cornering |
Operational State | 12V Ignition Input, Movement / Vibration | Active Run State, Idle Hours, Cumulative Run Hours, Odometer ($km$) |
Security & Safety | Tamper Switches, Digital Inputs | Unauthorised Movement, Door Open/Close, Remote Engine Immobilisation |
Bluetooth Scans | BLE MAC Addresses, Eddystone / iBeacon IDs | BLE Driver ID, Tool Inventory Scanning, Workforce Zone Headcount |
Summary & Next Steps
Key Takeaway: Devices collect live spatial and operational data across site assets, sending telemetry to Tobe Twin for real-time tracking, safety monitoring, and utilisation reporting.
