Women's Safety Bangle &Tracking Alerts by using GPS with Live Location - GSM CALL / SMS Notification

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. ________________________________________ 📌 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. ________________________________________ 📌 FULL PROJECT DESCRIPTION 1.

ELECTRICAL DESIGN CONSIDERATIONS 6.1 RF Link Reliability • Static addressing (HT12E/D) prevents cross-triggering • Antenna: λ/4 whip (~17.3 cm) improves range to 100–200 m • Supply decoupling: 10 µF + 100 nF capacitors across RF receiver 6.2 Noise Immunity • Pull-down resistors added to data lines • Twisted pair wiring for RF module data/ground • Separate analog and digital ground paths around GPS/GSM 6.3 GSM Power Stability SIM800 requires peak current >2 A; hence: • Add 1000 µF electrolytic + 100 nF ceramic at the power rail • Use buck converter (LM2596) instead of AMS1117 (insufficient current) 6.4 GPS Sensitivity • Ensure unobstructed sky view • Add backup coin cell (3 V) for warm-start performance ________________________________________ 📘 7.

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. ________________________________________ CHAPTER 5 – BLOCK DIAGRAM (Simple) Transmitter Unit [SOS Button] --> [HT12E Encoder] --> [RF Transmitter] Receiver Unit [RF Receiver] --> [HT12D Decoder] --> [Arduino] | ---------------------------------------- | | | | [GSM] [GPS] [LCD] [LED + Buzzer] ________________________________________ CHAPTER 6 – WORKING PRINCIPLE (Easy Explanation) Step 1: SOS pressed The woman presses the SOS button on the pouch/bangle. Step 2: Signal sent The HT12E encoder creates a digital signal and sends it using RF transmitter. Step 3: Signal received The RF receiver at the base station picks up the signal. HT12D decoder sends the output to Arduino. Step 4: Arduino actions The Arduino: • Turns ON red LED • Activates buzzer • Reads GPS location • Prepares emergency message Step 5: Sending Alerts Using GSM module, Arduino sends: • SMS Alert with GPS location • Phone Call to family Step 6: Display The LCD shows: • “SOS received” • “Getting location” • “Sending SMS” ________________________________________ CHAPTER 7 – CIRCUIT DIAGRAM DESCRIPTION (Simplified) Transmitter • SOS button → HT12E input • HT12E → RF Transmitter • Powered by 3.7 V battery Receiver • RF Receiver → HT12D → Arduino pin • Arduino connected to GSM and GPS • LEDs and buzzer connected to output pins • LCD connected in 4-bit mode ________________________________________ CHAPTER 8 – SOFTWARE FLOWCHART (Easy) START | V Initialize GSM, GPS, LCD | V Wait for RF SOS Signal | V If SOS Received? YES → Alarm ON, Red LED ON Read GPS Coordinates Send SMS with location Make Emergency Call Show info on LCD NO → Continue waiting | V END ________________________________________ CHAPTER 9 – KEY FEATURES • Small, portable, easy to carry • Works without internet • Sends SMS and calls automatically • Accurate GPS location tracking • Low power consumption • Affordable and easy to build ________________________________________ CHAPTER 10 – APPLICATIONS • Women safety • Students traveling alone • Elderly people • Night-shift workers • Trekking and outdoor safety ________________________________________ CHAPTER 11 – ADVANTAGES • Fast emergency response • Works even in remote areas (GSM available) • Simple button-press operation • Reliable RF communication • Local alert through buzzer and LEDs ________________________________________ CHAPTER 12 – LIMITATIONS • RF range limited to about 100 meters • Needs mobile network for SMS/call • GPS may take time to get signal indoors ________________________________________ CHAPTER 13 – FUTURE SCOPE • Mobile app integration • Two-way voice communication • SOS auto-activation with shock sensor • Cloud data storage • Real-time GPS tracking map ________________________________________ CHAPTER 14 – CONCLUSION This project successfully provides a simple and effective safety solution for women. It uses RF communication for emergency triggering and GPS + GSM for sending alerts and location. The device is low-cost, easy to carry, and can be life-saving in dangerous situations. It increases confidence and ensures help can reach quickly.
