T381 OBDII GPS Tracker — Plaspy Compatible

The T381 is a plug-and-play OBDII GPS tracker designed for easy integration with Plaspy. Built around a 4G LTE modem and an internal u‑blox GNSS module, the T381 delivers reliable real-time tracking, vehicle telemetry and integrated anti-theft control through an immobilizer output. Its OBDII and SAE J1939 support lets Plaspy collect engine parameters and diagnostic trouble codes (DTCs) for fleet management and preventative maintenance.

The device includes a built-in Wi‑Fi hotspot and Wi‑Fi bridging to reduce mobile data usage for connected terminals, plus a compact form factor and internal backup battery for simple installation and uninterrupted reporting. Whether you need fleet management, fuel monitoring or anti-theft immobilization, the T381 is Plaspy compatible and ready for rapid deployment.

Key Highlights

• Plug-and-play OBDII installer experience for fast vehicle onboarding with Plaspy.
• Real-time tracking via 4G LTE with fallback to 3G/2G to maintain location and telemetry continuity.
• Full OBDII and SAE J1939 telemetry: RPM, speed, engine coolant temperature, fuel level, fuel consumption and DTCs for fleet diagnostics and fuel monitoring.
• Built-in Wi‑Fi hotspot (up to 10 clients) and Wi‑Fi bridging to reduce cellular data costs for in-cab devices.
• Anti-theft capability with a digital immobilizer (engine cut) output to enable remote immobilization from Plaspy.
• Advanced motion and driver behavior detection with a 3‑axis accelerometer and event detection for harsh braking, acceleration and cornering.
• FOTA updates over 4G LTE or Wi‑Fi for streamlined remote management and firmware maintenance.
• Works alongside Plaspy deployments that include Bluetooth sensors — the T381 focuses on OBDII and Wi‑Fi telemetry while Plaspy can aggregate Bluetooth data from compatible peripherals.

How It Works with Plaspy

When paired with Plaspy, the T381 becomes an integrated telematics endpoint that streams location, diagnostics and driver-event data to your Plaspy dashboard in real time. Installation is straightforward: plug the T381 into the vehicle’s OBDII port and Plaspy begins receiving OBD parameters and GNSS position reports. Data can be used for live vehicle tracking, automated alerts, and historical reporting.

• Real-time location and telemetry updates from the u‑blox GNSS and OBDII parameters.
• In-time DTC monitoring and OBD II parameter alarms for fast diagnostic workflows.
• Fuel monitoring and fuel consumption data sent to Plaspy for efficiency reporting and cost control.
• Immobilizer (engine cut) digital output controlled through Plaspy for anti-theft and secure recovery workflows.
• Driver behavior and safety events (harsh braking, acceleration, cornering) delivered as actionable events for coaching and compliance.
• Wi‑Fi hotspot and Wi‑Fi bridging reduce cellular usage for in-cab tablets and devices while still allowing the T381 to maintain connectivity to Plaspy.
• FOTA via 4G or Wi‑Fi ensures the tracker firmware stays current and compatible with Plaspy features and protocols.

Technical Overview

Use Cases

• Fleet management: live GPS tracker and OBD telemetry for routing, utilization, maintenance planning and driver scoring.
• Anti-theft and immobilization: remote engine cut control plus location reporting for vehicle recovery and security workflows.
• Fuel monitoring & telemetry: continuous fuel level and consumption data to reduce waste and improve efficiency.
• Rental, insurance and vehicle profiling: in-time DTCs and driving behavior events for usage-based services and claims investigation.
• Roadside assistance and diagnostics: immediate access to engine trouble codes and vehicle status for faster service dispatch.

Why Choose This Tracker with Plaspy

The T381 delivers a compact, OBDII-based GPS tracker that plugs into the vehicle and immediately extends Plaspy with engine-level telemetry and accurate GNSS positioning. Its combination of 4G connectivity, Wi‑Fi hotspot/bridging and FOTA provides operational flexibility: devices stay updated, in-cab terminals can conserve mobile data, and fleet telemetry continues even in marginal cellular conditions. For operators focused on real-time tracking, fuel monitoring, anti-theft immobilization and driver behavior insights, the T381 offers a practical, Plaspy compatible solution that balances performance and ease of deployment.
