1. Circuit Diagram:

The circuit diagram illustrates the electrical connections of the women safety device. It includes components like the Arduino UNO, SIM900A GSM module, GPS module, JHT162A display, push button, buzzer, and power source. Each component is connected to specific pins of the Arduino for communication and control, showing how the device operates as a single system.

2. Block Diagram:

The block diagram simplifies the functionality of the device by breaking it into key modules:

Input Module: Push button for triggering the system.

Processing Unit: Arduino UNO for processing inputs and managing actions.

Communication Module: SIM900A GSM module for sending SMS.

Tracking Module: GPS module for retrieving location.

Output Module: Buzzer or vibration motor for alarms and JHT162A display for feedback.

This high-level overview explains the flow of information and the interaction between various components.

3. Flowchart:

The flowchart visualizes the working process of the women safety device step-by-step:

Start when the device is powered on.

My Role on the Team:

I took on the role of Lead Developer and Designer for the women safety device project. My responsibilities included designing the circuit, coding the Arduino for functionality, and integrating components like the SIM900A, GPS module, and alarm system. Additionally, I created the diagrams (circuit, block, and flowchart) to illustrate the working of the system and ensured the final device was user-friendly and reliable.

Collaboration:

To achieve the project goals, I worked closely with:

• Hardware Specialist: Helped assemble and troubleshoot physical connections and ensure proper wiring.

• Programmer: Assisted in debugging and optimizing the Arduino code for seamless communication between modules.

• Documentation Lead: Collaborated to prepare detailed project reports, diagrams, and presentations.

• Testers: Conducted field testing to validate GPS accuracy, SMS delivery, and overall device performance.

Outcome of the Project:

The project successfully resulted in a fully functional women safety device named "Guardian Angel". The device was able to:

• Trigger an alarm and alert nearby individuals.

• Send accurate location updates to emergency contacts via SMS.

• Operate in panic mode for continuous updates.

The device was well-received during demonstrations, highlighting its practicality, affordability, and potential to improve women's safety. The team gained valuable experience in hardware integration and teamwork, and the project laid the groundwork for further improvements.
