Arduino-Based-Real-Time-Security-Alert-System

This Python script monitors a serial connection (specifically to an Arduino device) and sends an email alert whenever new data is received.

Key Components

Libraries Used

• time: Manages timing functions.
• serial: Facilitates serial communication with the Arduino.
• smtplib and ssl: Enable secure email sending via Gmail.
• EmailMessage from email.message: Constructs the email content.

Hardware

• PIR Sensor: Detects motion and triggers the alert system.

Email Configuration

• The script sets up the subject and body for the email alert.
• Sender and receiver email addresses are specified, and the sender's email password is securely obtained through user input.

Email Composition

• An EmailMessage object is created with HTML content to indicate a security alert.

Serial Connection

• Establishes a connection with the Arduino on COM5 at a baud rate of 9600.
• Includes a one-second pause to stabilize the connection.

Data Monitoring Loop

• An infinite loop checks for incoming data from the Arduino.
• When data is available, the script reads the data packet, decodes it, and strips any unwanted newline characters.

Email Sending

• Upon receiving new data, the script logs into the Gmail SMTP server using the provided credentials and sends the constructed email.
• Success messages and the received data packet are printed to the console.

Use Case

This script is ideal for security applications where real-time monitoring and alerting are crucial, allowing users to receive immediate notifications when specific events, such as motion detected by the PIR sensor, occur in the connected Arduino device.
