SinoTrack - ST-902A

The ST-902A New Mini OBD GPS Tracker is a compact, plug-and-play OBD-II locator engineered for fast deployment and reliable vehicle monitoring. As a Plaspy compatible option, the ST-902A connects to online platforms via GPRS and is configurable by SMS, making it straightforward to point the device to a Plaspy server for real-time tracking, alerts and historical playback without rewiring vehicles.

Designed for fleet managers, rental operators and vehicle owners who prioritize quick installation and dependable telemetry, the ST-902A delivers position, movement and alarm data from any standard 16-pin OBD port. With a built-in backup battery, quad-band GPRS connectivity and u-blox GNSS performance, it provides the core GPS tracker features needed for fleet management, anti-theft alerting and everyday monitoring when integrated with Plaspy.

Key Highlights

• True plug-and-play OBD-II installation — no wiring or professional installation required.
• Plaspy compatible via configurable server IP/port — point device to your Plaspy instance using simple SMS commands.
• Real-time tracking over GPRS with SMS fallback for locations and alerts.
• Built-in 150 mAh backup battery keeps reporting for several hours after vehicle power loss (anti-theft resilience).
• Robust alert set: shock/vibration alarm, low battery, overspeed and geo-fence notifications for immediate telemetry and safety actions.
• Quad-band GSM/GPRS (850/900/1800/1900 MHz) for broad global coverage.
• Compact OBD form factor ideal for fleet vehicles, rentals and light commercial use.

How It Works with Plaspy

The ST-902A sends GPS position and alarm telemetry to an online server via GPRS (and can use SMS for direct commands or fallback). To integrate with Plaspy, configure the device’s server IP/port and APN settings using its SMS command set so the tracker posts packets directly to your Plaspy endpoint. Plaspy then ingests the incoming data to deliver real-time tracking, event alerts and route history in your dashboard and mobile apps.

• Real-time location and telemetry updates via GPRS to your Plaspy server.
• Alarm and event reporting: shock/vibration, overspeed, low battery and geo-fence triggers.
• GPRS online mode with SMS command/config and SMS fallback for offline or emergency messaging.
• Configurable IMEI handling and registration support for country compliance; IMEI can be queried or changed by SMS within device limits.
• Simple SMS configuration enables fast on-site setup and connection to Plaspy without specialised tools.

Technical Overview

Use Cases

• Fleet monitoring and basic telemetry — deploy across cars and light trucks for real-time location, overspeed alerts and route history for compliance and operational oversight.
• Anti-theft and recovery — instant vibration/shock and low battery alerts when the vehicle is tampered with; backup battery keeps the device reporting during short power cuts.
• Rental car and short‑term vehicle programs — plug-in OBD convenience makes swapping and redeploying trackers fast without wiring or shop time.
• Geofence-based operations — receive geofence entry/exit notifications for perimeter control, delivery zones and asset movement tracking.
• Remote sites or secondary vehicle monitoring — use SMS configuration to point devices to Plaspy and receive location or alarm updates where GPRS is the primary transport.

Why Choose This Tracker with Plaspy

The ST-902A is a pragmatic choice when you need a Plaspy compatible GPS tracker that minimizes installation time while delivering the essentials of fleet management and anti-theft telemetry. Its OBD-II plug-and-play design and SMS-configurable server settings let you register devices quickly on Plaspy without additional hardware or wiring. Quad-band GPRS and a u‑blox GNSS engine provide reliable coverage and positioning accuracy for everyday use.

While this model focuses on straightforward location, alarm and telemetry reporting (it does not include dedicated fuel monitoring, ignition input pins or built-in immobilizer/BLE sensors), its simplicity is an advantage for fast rollouts. If your Plaspy deployment requires advanced I/O (ignition sensing), fuel monitoring or remote immobilizer control, you can pair the ST-902A’s tracking data with additional hardware or select a Plaspy-compatible model that exposes those interfaces. For teams who want an easy-to-install, robust GPS tracker that integrates with Plaspy for real-time tracking and fleet management, the ST-902A is a reliable, low-cost option backed by manufacturer support and a two-year warranty.
