The Ulbotech L101 is a compact OBD GPS data logger designed for plug-and-play vehicle telemetry and is Plaspy compatible for straightforward integration into fleet and asset management workflows. Combining a u‑blox 6M GNSS module, an OBDII reader that supports all common protocols, Bluetooth 4.0 Low Energy (BLE), and a 3‑axis accelerometer, the L101 provides real-time tracking and rich vehicle telemetry without complex wiring. Its plug-in OBDII form factor and onboard microSD storage make it ideal for long-term data capture, driver behavior monitoring, and anti-theft measures.
As a GPS tracker engineered for fleet management, insurance telematics, and rental monitoring, the L101 delivers accurate position fixes, OBDII diagnostics, and driving-event detection that Plaspy can ingest for alerts, reports, and automated workflows. With fuel monitoring, geo-fence enforcement, and an immobilizer output for engine cut use, the L101 helps fleet operators and service providers turn raw vehicle data into actionable insights through Plaspy’s real-time tracking and reporting capabilities.
Key Highlights
- Plug-and-play OBDII installation for quick deployment across fleets and rental vehicles.
- High-sensitivity u‑blox 6M GNSS for accurate GPS tracking (position accuracy ~3 m autonomous).
- Comprehensive OBDII telemetry: supports J1850, ISO 9141-2, ISO14230, ISO15765 (CAN) protocols.
- Built-in BLE 4.0 for mobile live monitoring and connections to Bluetooth sensors or smartphones.
- Driver behavior detection (8 event types) and configurable geo-fences (circle, rectangle, polygon up to 32 points).
- Internal microSD (up to 4 GB) and micro USB U‑disk for local data access and simple data transfer.
- Anti-theft capability via an internal immobilizer (engine cut) output and alarm generation based on OBDII data.
How It Works with Plaspy
When deployed with Plaspy, the Ulbotech L101 provides continuous vehicle location and detailed telemetry that Plaspy uses for real-time tracking, alerts, and historical reporting. The L101 records GPS coordinates and OBDII parameters and sends recorded data to servers or mobile gateways for ingestion by Plaspy. Plaspy then normalizes GPS tracker and OBD telemetry, enabling fleet managers to monitor routes, fuel use, ignition state, and driver behavior from a single dashboard.
- Real-time location and telemetry updates (GPS position, speed, heading) for Plaspy dashboards.
- OBDII data and diagnostics: RPM, engine parameters, and fuel-related PIDs for fuel monitoring and vehicle health.
- Driver behavior events from the accelerometer (rapid acceleration, harsh braking, cornering) and configurable thresholds.
- Immobilizer output state and ignition-related signals recorded for anti-theft workflows and incident response.
- BLE connectivity enables mobile live monitoring and can be used with Bluetooth sensors or smartphones to forward data to Plaspy when paired.
