Summary of "Arduino Gps And Gsm Based location Tracking System | Women Safety Device Small Version"

Summary of Technological Concepts, Product Features, and Analysis

Project Overview

The video demonstrates a compact Arduino-based GPS and GSM location tracking system designed primarily as a women’s safety device. The system can send location alerts and make emergency calls.

Core Components

Microcontroller: Arduino Nano
GPS Module: Neo 6M GPS module (referred to as “new 6m GPS model”)
GSM Module: SIM800L GSM module for communication
Power: 3.7V rechargeable lithium-ion battery (500mAh) with a TP4056 battery charger module
User Interface: Two push buttons for triggering actions
Additional Hardware: Sliding on/off switch, resistors (10k), and voltage divider circuits for push button input stabilization

Functionality

Push Button 1: Sends an SMS containing a predefined alert message (“I need help”) along with GPS coordinates (latitude and longitude) via GSM. The message includes a Google Maps link for easy location tracking.
Push Button 2: Initiates a voice call to a preset phone number, allowing the receiver to listen in clearly to the caller’s surroundings.
The device powers on/off via a sliding switch.
The battery can be recharged via a USB cable connected to the TP4056 charger module.

Circuit and Wiring Details

GPS module VCC connected to 5V or 3.7V supply, TX/RX pins connected to Arduino RX/TX pins.
GSM module powered by 3.7V supply, with TX/RX connected to Arduino digital pins (D2, D3).
Push buttons connected using pull-up resistors to Arduino digital input pins (pin 4 and pin 5).
Ground connections are common for all modules.

Software and Code

Uses Arduino IDE with libraries: TinyGPS.h, SoftwareSerial.h, and GSM-related libraries.
Code defines push button pins and mobile number (including country code) for SMS and calls.
On pressing button 1, the device sends an SMS with GPS location and alert text.
On pressing button 2, the device calls the preset number.
The code is uploaded to Arduino Nano with ATmega328P processor and bootloader selected.
The presenter provides the code on their website for download and customization.

Demonstration

The presenter shows the device sending an alert SMS with a Google Maps link that opens the exact location.
The GSM module makes a call to the saved number, and the call audio is clear, enabling the recipient to listen to the environment.
The device is compactly assembled on a small PCB.

Additional Notes

The device is intended for women’s safety but can be adapted for general location tracking and emergency alerting.
The presenter encourages viewers to ask questions in comments and provides troubleshooting tips for code uploading.

Main Speaker/Source

The video is presented by a single individual focused on electronics tutorials, likely the channel owner or creator of the project, who explains the hardware assembly, circuit diagram, code, and live demonstration.
