Story

DIY Motion-Activated Security System with SMS Alerts

Introduction:

Modern times call for modern solutions, and when it comes to securing our spaces, innovation takes the front seat. In this project, we'll walk through the creation of a DIY Motion-Activated Security System powered by a D1 mini and a GSM800L module, ensuring your peace of mind with real-time SMS alerts.

Project Overview:

Imagine having a smart security system that not only detects unwanted motion but also instantly alerts you via SMS. This project accomplishes just that, thanks to the fusion of cutting-edge technology and a dash of creativity. Using a D1 mini and a GSM800L module, we've built a compact and efficient security solution that's perfect for homes, offices, or any place you want to safeguard.

Components Used:

ESP8266 D1 mini: The brains behind our project, this microcontroller processes motion sensor data and manages the SMS alerts.
PIR Motion Detector: Our electronic "guard dog, " this sensor detects movement and triggers our security system.
GSM800L Module: The communicator of our system, this module sends out SMS alerts when motion is detected.

GSM800L Module Pinout:

VCC: Connect to 5V power supply.
GND: Connect to the ground (GND) of D1 mini.
TXD: Connect to the RX (receive) pin (D6) on the D1 mini.
RXD: Connect to the TX (transmit) pin (D7) on the D1 mini.

A SMcard: For text communication
Tripler Adapter: Ensures smooth connectivity and reduces clutter, allowing for an organized setup.

How It Works:

1. Sensing Intrusion: The PIR motion detector acts as our vigilant sentry, keeping a watchful eye on the surroundings.

2. Motion Detection: When the motion detector senses movement, it sends a signal to the D1 mini, activating our security system.

3. Instant SMS Alert: The D1 mini communicates with the GSM800L module to send an SMS alert to your mobile phone, notifying you of the intrusion.

4. Real-Time Monitoring: With the SMS alert in hand, you can take immediate action, whether it's notifying authorities or checking the situation remotely.

How your setup should look like

Building the System:

1. Hardware Setup: Connect the components as per the provided schematic, ensuring proper power and communication.

2. Coding Magic: Upload the provided Arduino code to your D1 mini. This code integrates the PIR sensor and GSM module, orchestrating their synchronized performance.

3. Deploy and Protect: Place the motion sensor strategically, ensuring it covers the desired area. Power up your system and rest assured, knowing your space is now fortified.

COOL YOU MADE IT!!!

Conclusion:

With our DIY Motion-Activated Security System, you've taken control of your safety. Gone are the days of worrying about security breaches when you're away. Whether it's your home, office, or any personal space, this smart system will alert you in real-time, allowing you to respond swiftly. Embrace technology, build your security solution, and enjoy a safer world.

Remember: Security is a paramount concern. While this project adds an extra layer of protection, it's important to combine it with other security measures to ensure comprehensive safety.

}

{
  PIRState = digitalRead(PIR);

  if (PIRState == HIGH) {
    Serial.println("Sensor detects motion");
    SendSMS(); // Send SMS every time motion is detected
    delay(2000); // Delay for stability
  } else {
    Serial.println("No motion detected");
  }

  while (sim800l.available()) {
    Serial.write(sim800l.read());

  sim800l.print("Security alert | Intruder detected!");
  sim800l.write(26); // Send Ctrl+Z to indicate end of SMS
  delay(500); // Give time for the module to process
  while (sim800l.available()) {
    Serial.write(sim800l.read());
  }
}

void updateSerial()

  while (sim800l.available()) {

    Serial.write(c);
