Introduction

Salam alikom and welcome to this new project from open hardware Algeria which is part of the series dedicated to the use of GPS modules in open source hardware prototypes. This project will show you our connected GPS Tracker project using GPRS technology. We will present the hardware components that form our device, followed by a test of our device. For the purposes of this project we have set ourselves a number of goals which are:

• The device must be based on an Arduino architecture, specifically that of an Arduino UNO;

• The assembly must be simple;

• The program must use standard and easy-to-use libraries.

EXPANDED TECHNICAL DETAILS

Long-Range Asset Monitoring Hub

This project delivers a robust, cellular-based tracking solution for vehicles or expensive equipment, capable of reporting its location worldwide.

• NMEA Coordinate Acquisition: The Arduino interfaces with a NEO-6M GPS module. The firmware parses the raw satellites' strings into Latitude, Longitude, and Speed variables with meter-level accuracy.
• GSM Serial Handshake: Uses an SIM900 or SIM800 module to transmit the GPS data to a remote server or a user's phone via SMS/GPRS. The Arduino manages the AT-command pipeline to ensure a stable cellular connection.

Efficiency

• Motion-Triggered Sleep: Includes a vibration sensor or accelerometer; the GPS and GSM modules only wake up and transmit when the asset is physically moving, drastically extending battery life.
