Overview
The Hawk Data Logger (Digital Matter Hawk Pro) is a modular, weather-proof sensor hub and data logger engineered for civil construction and geotechnical telemetry.
Featuring interchangeable I/O cards, the Hawk connects to external sensors (e.g., piezometers, inclinometers, dust/noise monitors, energy meters) while functioning as a long-range Bluetooth Low Energy (BLE) gateway across site workfronts.
Target Applications
The Hawk Data Logger is deployed for:
Environmental & Geotechnical Monitoring: Logging groundwater pressure, tiltmeter angles, and structural settlement.
Site Utility & Energy Logging: Monitoring 3-phase power meters, water flow meters, and fuel tank levels.
Consumables & Material Tracking: Tracking high-value spools, cable reels, and steel beams via BLE gateway scanning.
Remote BLE Gateway: Receiving telemetry from nearby BLE tags within 50m radius.

Telemetry & Implied Analytics
RAW Data Captured:
Sensor Measurements: Digital and analog readings from connected instruments (e.g., pressure $kPa$, voltage, pulse counts).
BLE Gateway Telemetry: Scanned MAC addresses, RSSI signal strength, and Eddystone IDs from nearby BLE tags.
Location & Diagnostic Data: GPS location coordinates, battery voltage, solar charging status.
Implied Platform Analytics:
Sensor Trend Analysis: Real-time threshold tracking, trend graphs, and alert notifications in 4D Viewer.
BLE Tag Location Estimation: Implied spatial position (within 50 meters of the Hawk gateway) for tracked materials and tools.
Location History: Movement trail of tracked items based on gateway coordinates over time.
Summary & Next Steps
Key Takeaway: The Hawk Data Logger bridges specialized site sensors and BLE tags directly into the Tobe Twin platform for real-time geotechnical, utility, and material tracking.
Next Steps: See BLE Device - Minew Helmet Tags for wearable tags scanned by the Hawk gateway.
