Introduction:

The project is based on woman safety. Taking the help of modern engineering and technology we have designed a bag in which a secret GPS tracker is attached. By using this bag we can get the exact geographical location of a place. The bag must be carried with a woman while going outside. If unfortunately there is some trouble with the female, we can track her location and rescue her by getting the exact latitude and longitude from the GPS tracker containing bag.

Components required:

1. Battery
2. Switch
3. Nodemcu
4. Buck converter
5. GPS module
6. GSM module
7. 7805 voltage regulator
8. Connecting wire
9. Charger

Working:

A female individual has to carry the GPS tracker containing bag with her while going away from home. Before starting the journey she has to switch the tracker on. This system operates with a battery. After getting connected with the satellite, the GPS module sends the exact latitude and longitude values to nodemcu. Nodemcu sends the data as a text message by the help of a GSM module to a family member’s mobile phone. When these values are fed to Google map, we get the exact geographical location of that place. If unfortunately there is some trouble with the female, now we can reach at her location and rescue her. This system delivers the current location values in regular interval of time.

Advantage

A female individual can be protected by using this bag.

Component description

Battery

A battery stores electric charge. When we discharge a battery, the stored chemical energy is converted into electrical energy. When we charge a battery, electrical energy is converted into chemical energy. A battery always supplies us DC.

7805 voltage regulator

The 7805 voltage regulator IC gives us an output of constant 5 volt DC from a DC input voltage higher than 5 volt. The remaining voltage is dissipated as heat in the heat sink provided to the voltage regulator IC.

Nodemcu

It contains a microcontroller. A microcontroller is a compressed microcomputer which acts by getting commands through software program.

Switch

A switch can connects and disconnects the conduction of electricity in a circuit.

Sim800l version 2

It is the second version of SIM800L GSM Module. It is a miniature GSM modem. It takes a SIM card just like our mobile phone. We can make or receive a call, send a text message and connect to the internet through GPRS by using it. GSM stands for Global System for Mobile communication.

Buck converter

Here it supplies us a constant 5 volt DC power supply from a 8 volt DC.

GPS module

It contains tiny processor and antenna which directly receives data sent by satellites through dedicated RF frequencies.

Code for microcontroller

// Su-Din Technology contact 9861004895
// Interfacing GPS and GSM with Nodemcu

#include <TinyGPS++.h>
#include <SoftwareSerial.h>
const int RXPin = 4, TXPin = 5;
const uint32_t GPSBaud = 9600;
TinyGPSPlus gps;
SoftwareSerial GPS(RXPin, TXPin);
char phone_no[]="9861004895"; // your 10 digit phone number
void setup(){
  Serial.begin(9600);
  //delay(1500);
  GPS.begin(GPSBaud);
  //delay(1500);
  //Enable textmode of GSM
  Serial.println("AT+CMGF=1");
  delay(5000);
  }

void loop(){
  while (GPS.available() > 0){
  gps.encode(GPS.read());
  if (gps.location.isUpdated()){
  Serial.print("AT+CMGS=\"");
  Serial.print(phone_no);
  Serial.println("\"");
  delay(200);
      Serial.print("  LATITUDE= "); 
      Serial.print(gps.location.lat(), 6);
      Serial.print(" LONGITUDE= "); 
      Serial.println(gps.location.lng(), 6);
      delay(20000); 
      //Sends CTRL+Z end of message
      Serial.write(0x1A); 
      //delay 20 second after getting a new message
      delay(20000); 
    }
  }
}
