The PT-35 Personal Tracker from PT-series (PT-35) is a compact, rugged GPS tracker designed for reliable Plaspy compatible deployments where discretion, long battery life, and flexible I/O are required. Combining u‑blox GNSS positioning with a quad-band GSM modem (GPRS/SMS/voice), the PT-35 delivers accurate location and event telemetry for personal safety, asset security and vehicle monitoring while integrating smoothly with Plaspy for real-time tracking and centralized fleet management.
The unit is optimized for ultra-low-power, schedule-driven operation and supports comprehensive I/O for alarms, motion detection and external sensors. Plaspy-compatible by design, the PT-35 supports GPRS TCP/IP and SMS transport so location reports, panic alerts, and stored messages can be forwarded to Plaspy for live maps, alerts and historical reporting — making it a practical choice for anti-theft, personnel safety and telemetry use cases.
Key Highlights
- Plaspy compatible: delivers GPRS/SMS location and event data to Plaspy for real-time tracking and reporting.
- Long-life operation: configurable deep-sleep and timer modes extend standby from days to multi-year timer retention under optimal conditions.
- Compact and rugged: pocket-sized design with optional waterproof magnetic housing for covert or harsh-environment installs.
- Rich I/O for telemetry: digital and analog inputs plus multi I/O connector support external sensors, panic inputs and alarm signals.
- Panic and voice support: built-in microphone/speaker and panic inputs enable hands-free voice calls and immediate tracking on alarm.
- Onboard storage: automatic storage of up to 5,000 position/activation messages for delayed upload or recovery scenarios.
- Flexible power options: USB +5V input, built-in charging for a 3.7V Li‑ion battery and support for external battery/solar input.
How It Works with Plaspy
Integration with Plaspy leverages the PT-35’s GSM data and messaging capabilities to deliver frequent, reliable updates to your Plaspy dashboard. The tracker can be configured to wake on a schedule, on motion, or on panic input; when awake it sends GPS coordinates and telemetry by GPRS (TCP/IP) or SMS to Plaspy so you receive up-to-the-second location, status and alert information.
- Real-time location and telemetry updates via GPRS (TCP/IP) or SMS for continuous tracking in Plaspy.
- Panic button and hands-free voice: immediate alerting and two-way voice support routed alongside location for rapid response.
- Motion and tamper alerts: built-in accelerometer and external panic/tamper input trigger instant Plaspy alerts when movement or cable cut is detected.
- Stored message upload: up to 5,000 buffered messages can be uploaded to Plaspy after network reconnection for complete history.
- Digital/analog I/O telemetry: use the digital input for ignition/door/alarm status and the analog input for external sensor readings (e.g., fuel-level transmitter) when wired by an installer.
