Real-Time GPS Tracker
A low-latency, end-to-end asset monitoring solution that pairs custom PCB hardware with a real-time web dashboard.
Overview
To address the need for cost-effective and autonomous fleet management, this project realizes a complete IoT ecosystem from hardware-level execution to frontend data visualization. The system architecture utilizes a dedicated microcontroller integrated with GPS and GSM modules on a custom-designed PCB to acquire geo-coordinates and transmit them via cellular networks. On the software side, a robust High-Level Design (HLD) orchestrates data ingestion into an optimized SQLite database, driving a responsive React dashboard that renders real-time asset paths seamlessly.
Key Technical Achievements
Hardware & PCB Architecture
Engineered and routed a custom PCB integrating a core microcontroller chip with GPS and GSM modules, successfully stabilizing cellular telemetry and power distribution for continuous field operation.
Telemetry Data Pipeline
Formulated a reliable high-level design (HLD) to manage the data lifecycle, ensuring raw NMEA location strings are parsed efficiently at the edge before transmission via GSM networks.
Full-Stack Integration & Storage
Implemented a lightweight backend using an optimized SQLite database to handle rapid location write-logs, fueling a live React dashboard that delivers real-time coordinate rendering with minimal stream latency.
