Below is a complete, ready-to-use Abstract, Full Description, Block Diagram / Flowchart (text-based), and Working Explanation for your Women Safety Pouch/Bangle System using RF433 MHz, GSM, GPS, Arduino, HT12E/HT12D.
________________________________________
๐ ABSTRACT
Women’s safety has become a crucial concern in modern society. To address this issue, this project proposes a Smart Women Safety System integrated into a pouch or wearable bangle, consisting of a Transmitter Unit and a Receiver Unit.
The transmitter unit is compact and wearable, equipped with an SOS emergency switch, HT12E encoder, and an RF 433 MHz transmitter module, powered by a small battery. When the woman presses the SOS switch, an encoded RF emergency signal is instantly transmitted.
The receiver unit includes an RF 433 MHz receiver, HT12D decoder, Arduino Uno (ATmega328) controller, GPS module, GSM module, 16×2 LCD, and safety indicators such as LEDs and buzzer alarm. Upon receiving the SOS signal, Arduino retrieves the live GPS location and sends SMS/Call alerts to pre-saved emergency contacts through the GSM module. The alarm and LED indicators provide instant local alerting.
This project provides a low-cost, reliable, and effective safety system using long-range RF communication and real-time GSM–GPS location tracking to support women in emergency situations.

⭐ PROJECT REPORT (School-Level)
Women Safety Device using RF, GSM, GPS and Arduino
________________________________________
CHAPTER 1 – INTRODUCTION
Women’s safety is one of the most important issues today. Many women travel alone for school, college, work, and other daily activities. In some situations, they may feel unsafe or may need quick help.
To solve this, we created a Women Safety Device made in a pouch or wearable bangle. It consists of two units:
1. Transmitter (carried by the woman)
2. Receiver (kept with family/guardian)
When the woman presses the SOS button, a signal is sent using RF (433 MHz) to the receiver. The receiver then uses GPS to get the current location and GSM to send an emergency SMS alert or make a phone call to the family.
This system allows quick help in emergencies and improves safety.
________________________________________
CHAPTER 2 – AIM AND OBJECTIVE
Aim
To design a simple and low-cost device that allows women to send emergency alerts with location tracking.
Objectives
• To send an emergency signal using RF (Radio Frequency).
• To receive the signal and notify guardians.
• To track the exact location using GPS.
• To send an emergency SMS and call using GSM.
• To provide local alert using LEDs and Buzzer.
________________________________________
CHAPTER 3 – LITERATURE REVIEW (Simple)
Previously, researchers and engineers have tried many ways to improve women’s safety.
• Some systems used only mobile apps, but they require internet and battery.
• Some systems used GPS only, which cannot send alerts by itself.
• Some used panic buttons, but they did not include location tracking.
Our project is a combination of RF + GPS + GSM + Arduino, which makes it more reliable because it works without internet and gives accurate location.
________________________________________
CHAPTER 4 – HARDWARE USED (Simple Explanation)
1. RF Transmitter (433 MHz)
Sends the emergency signal wirelessly when the SOS button is pressed.
2. RF Receiver (433 MHz)
Receives the wireless signal from the transmitter.
3. HT12E Encoder
Converts the button press into encoded data so it can be sent via RF.
4. HT12D Decoder
Converts the RF signal back into usable data for the Arduino.
5. Arduino UNO (ATmega328P)
Main controller of the project. It:
• Reads SOS signal
• Gets GPS location
• Sends SMS/call through GSM
• Controls LCD and alarm
6. GPS Module
Gives the current latitude and longitude.
7. GSM Module (SIM800/SIM900)
Sends SMS and calls to emergency contacts.
8. LCD Display
Shows messages such as “SOS received”, “Sending SMS”, etc.
9. LEDs (Red & Green)
• Green: System ON
• Red: Emergency alert
10. Buzzer
Gives loud sound when SOS is received.
11. Battery
Provides power to the transmitter and receiver.
