Smart Pole – Be Smart and Safe 🚨🌐

A final-year Diploma project aimed at enhancing public safety through the integration of smart technology into urban street lighting infrastructure.

📌 Project Overview

Smart Pole is an innovative system that upgrades traditional streetlights with emergency response features. It is specifically designed to assist individuals in distress—particularly women and children—by allowing them to send an immediate alert to nearby police stations, while simultaneously activating lights, sirens, and GPS location tracking.

🎯 Aim

To develop a real-time emergency alert and response system embedded into smart street poles, enhancing public safety using:

• Distress button activation
• Siren and LED light alerts
• Real-time GPS tracking
• GSM-based SMS alerts

🔧 Components Used

Hardware

• Arduino Uno (Microcontroller)
• GPS Module (SIM28ML or equivalent)
• GSM Module (SIM900A)
• Buzzer
• LED Light (Red)
• Emergency Button
• 12V 2A Adapter
• Data Transfer Cable

Software

• Arduino IDE
• MS Word (Documentation)
• Web Browsers (Google Chrome, IE 6.0)

📐 System Workflow

1. Emergency button is pressed
2. Buzzer and siren are activated
3. LED light turns on to draw attention
4. GPS module retrieves real-time location
5. Message with coordinates is sent via GSM
6. Police receive location alert and respond

• Children in distressful situations

📸 Output

• SMS Alert: “ALERT HELP NEEDED” with GPS coordinates
• LED Indicator: Illuminates area during alert
• Buzzer/Siren: Audible signal for local awareness

📜 Sample Code Snippet

if (digitalRead(btnPin) == HIGH) {
  digitalWrite(ledPin, HIGH);
  delay(3000);
  digitalWrite(ledPin, LOW);
  sgsm.listen();
  sgsm.print("AT+CMGF=1\r");
  delay(1000);
  sgsm.print("AT+CMGS=\"+91XXXXXXXXXX\"\r");
  delay(1000);
  sgsm.print("https://www.google.com/maps/?q=");
  sgsm.print(gpslat, 6);
  sgsm.print(",");
  sgsm.print(gpslon, 6);
  delay(1000);
  sgsm.write(0x1A);
}

🧠 Future Enhancements

• Integration of camera modules with fisheye lenses
• Cloud-based data storage and analytics
• Mobile app interface for public use
• Solar power support for sustainability
