CAREU - U1 PLUS

The CAREU U1 PLUS is a robust GPS tracker purpose-built for fleet management, heavy trucks and commercial vehicle deployments. Green-Gps compatible out of the box, the U1 PLUS delivers reliable real-time tracking and rich vehicle telemetry over LTE Cat 4 / Cat 1 with fallback to 3G and 2G, making it an ideal GPS tracker for mixed-network environments and large-scale fleet operations.

Designed to integrate directly with Green-Gps, the U1 PLUS brings OBD II / CAN interpreter support (J1939 and J1708), advanced fuel monitoring, multi-sensor expandability and driver behaviour detection into a single device. Whether you need precise fuel monitoring, video-capable installations, or secure telematics for anti-theft and smart city projects, this Green-Gps compatible tracker scales to meet the demands of commercial fleets and specialized vehicle solutions.

Key Highlights

• Green-Gps compatible GPS tracker with LTE Cat 4 and Cat 1 connectivity for high-throughput real-time tracking and telemetry.
• Direct OBD II / CAN interpreter (J1939, J1708) — reads fuel level, odometer, RPM and engine temperature for accurate vehicle telemetry.
• Support for ultrasonic fuel sensors and analog/1-Wire temperature sensors for precise fuel monitoring and cold-chain management.
• 6-axis accelerometer for driver behaviour monitoring: harsh acceleration, braking, cornering, impacts and flip-over detection.
• Extensive connectivity options: GPS/GLONASS/QZSS (with optional BDS/Galileo), LTE/UMTS/HSPA/GPRS/EDGE, SMS, FTP and USSD.
• Multi-sensor expandability via RS-232 and optional RS-485 — connect dash cams, RFID readers, barcode scanners and fatigue sensors.
• Anti-theft and security features including eCall (112), GPS antenna tamper detection, power low/power lost alarms and GSM jamming detection (2G/3G).
• Remote management with FOTA (firmware updates over FTP) and optional AES-256 data encryption for secure deployments.

How It Works with Green-Gps

When paired with Green-Gps, the U1 PLUS streams location and vehicle telemetry to the Green-Gps platform using cellular links (LTE/3G/2G) or SMS/FTP/USSD as fallbacks. Green-Gps ingests and normalizes CAN/OBD data, accelerometer events and sensor inputs so fleet managers receive consolidated, actionable data for real-time tracking, alerts and historical reporting.

• Real-time location and telemetry updates via LTE Cat 4/Cat 1 with fallback to UMTS/HSPA and GPRS/EDGE.
• Vehicle telemetry from OBD II / CAN: fuel level, odometer, RPM, engine temperature and other J1939/J1708 parameters.
• High-accuracy fuel monitoring using ultrasonic sensors and analog/1-Wire temperature sensors for cold-chain visibility.
• Driver behaviour and safety events from the 6-axis accelerometer (harsh driving, impacts, flip-over).
• Geofence events (circular and polygonal), power loss/low power alarms, antenna tamper and GSM jamming alerts forwarded to Green-Gps.
• Accessory telemetry and video integrations via RS-232/RS-485 (dash cams, RFID, barcode scanners) for enriched monitoring and surveillance workflows.
• Wireless configuration and local pairing on supported models via Bluetooth; optional Wi‑Fi and internal hotspot on 4G Cat.4 variants for local access and video offload.

Technical Overview

Use Cases

• Fleet management and logistics: real-time tracking, RPM and odometer telemetry for route optimization and maintenance planning.
• Fuel monitoring and anti-theft: ultrasonic and OBD-derived fuel readings combined with tamper, jamming and power-loss alarms for fuel monitoring and security.
• Cold-chain transport: analog and 1-Wire temperature sensors for continuous temperature logging and alerts during refrigerated deliveries.
• Video transmission and surveillance: dash cam and DSC camera support via RS-232/RS-485 for live or recorded video linked to positional data.
• Specialized heavy vehicle deployments: garbage truck collection control, school/coach safety monitoring, agricultural asset tracking and smart city mobility projects.

Why Choose This Tracker with Green-Gps

The CAREU U1 PLUS delivers a balanced combination of connectivity, vehicle-level telemetry and expandability that makes it a strong choice for Green-Gps-compatible deployments. Its built-in OBD II / CAN interpreter means you get trusted engine and fuel metrics without complex gateway hardware, while support for ultrasonic fuel sensors and temperature probes adds the precision required for cold-chain and fuel-sensitive operations. Anti-theft protections — from antenna tamper detection to GSM jamming alerts and eCall support — improve security posture for high-value fleets.

For fleet managers using Green-Gps, the U1 PLUS reduces integration time by transmitting comprehensive telemetry over standard cellular protocols and offering FOTA for field maintenance. Optional AES-256 encryption, Bluetooth configuration and Wi‑Fi hotspot options on 4G models provide deployment flexibility across vehicle types and use cases. In short, the U1 PLUS is a Green-Gps compatible GPS tracker designed to scale from single-vehicle anti-theft projects to enterprise fleet management with multi-sensor telemetry, video and advanced reporting.
