Ulbotech - T381
The T381 is a compact plug and play OBDII GPS tracker from Ulbotech. Built around a 4G LTE modem and an internal u‑blox GNSS module, the device provides real time location reporting, vehicle telemetry and an immobilizer output for anti‑theft control. Its OBDII and SAE J1939 support lets it surface engine parameters and diagnostic trouble codes for fleet monitoring and preventative maintenance, while a built in Wi‑Fi hotspot and Wi‑Fi bridging help reduce cellular data use for in‑cab devices.
As a Plaspy compatible device, the T381 can stream location, OBD parameters and driver event data directly into Plaspy for live monitoring, alerts and historical reporting. That compatibility makes it suitable for rapid deployment across mixed vehicle fleets where immediate visibility into position, engine state and basic security control is required. Plaspy users can aggregate T381 data alongside other devices to support routing, maintenance planning and operational oversight.
Key Highlights
- Plug and play OBDII form factor for fast vehicle onboarding and immediate telemetry access.
- Real time GNSS tracking with cellular connectivity to report position and movement to Plaspy.
- Full OBDII and SAE J1939 telemetry including RPM speed coolant temperature fuel level fuel consumption and DTCs for diagnostics and reporting.
- Built in Wi‑Fi hotspot and bridging to reduce cellular usage for in‑cab terminals and connected devices.
- Integrated anti theft immobilizer output allowing remote engine cut control from a fleet platform.
- Internal backup battery and compact design to maintain reporting during short power interruptions.
How It Works with Plaspy
When used with Plaspy the T381 acts as a telematics endpoint that sends location and vehicle diagnostics into the Plaspy dashboard for real time visibility and historical analysis. Data from the OBD interface and the GNSS receiver populate Plaspy features for monitoring, alerts and reporting so operators can manage vehicles from a single platform.
- Live location updates and movement history visible in Plaspy for routing and tracking.
- Automatic delivery of engine diagnostics and DTC alerts to support maintenance workflows.
- Fuel level and consumption reporting available for efficiency analysis and cost control.
- Remote control of the immobilizer output via Plaspy for security and recovery procedures.
- Driver behavior and safety event reporting delivered as events for coaching and compliance.
- Reduced cellular usage for in cab devices through the T381 Wi‑Fi hotspot and bridging while maintaining connectivity to Plaspy.
Typical Use Cases
- Fleet management and utilization tracking for small to medium vehicle fleets.
- Anti theft workflows that combine location reporting with remote immobilization.
- Fuel monitoring and consumption analysis to identify inefficiencies and reduce costs.
- Rental and insurance fleets that require in time diagnostics and driving behavior insight.
- Roadside diagnostics and faster service dispatch using DTC and vehicle status reporting.
Why Choose This Tracker with Plaspy
