IoT primarily based Entry and Exit Monitoring System

The IoT primarily based Entry and Exit Monitoring System is an RFID-based answer for monitoring people getting into and exiting a monitored space. Every particular person scans their distinctive RFID tag upon entry or exit, and the system information the motion.

This data is displayed in real-time on an online server, indicating whether or not the person is inside or has left the realm, with color-coded markers (inexperienced for entry and purple for exit). Moreover, the online web page reveals the whole variety of folks at the moment inside the realm.

Key Learnings

• RFID Know-how: Using RFID tags and readers for automated identification and information seize.
• IoT Internet Server: Organising an online server on ESP32 to show reside information, making the system accessible remotely.
• Actual-time Monitoring: Capturing and displaying real-time entry and exit actions of people.
• Knowledge Dealing with: Storing and managing a number of RFID tags and their statuses.

Use Case and Utility

This method might be employed in numerous environments corresponding to:

• Workplaces: Monitor staff getting into and exiting workplaces.
• Occasions: Monitor the attendance of individuals.
• Instructional Establishments: Automate attendance monitoring of scholars.

The RFID-based IoT system is easy and environment friendly, offering a real-time overview of who’s contained in the monitored space, making it appropriate for safety and monitoring functions.

Working Clarification

1. When an RFID tag is scanned, the system checks if it’s a new entry or a repeat scan.
2. If it’s a new entry, the system logs the time, marks it as “entered” with a inexperienced dot, and will increase the counter of individuals inside.
3. If the identical RFID tag is scanned once more, it’s marked as “exited” with a purple dot, and the counter is decreased.
4. This information is displayed in real-time on a webpage, exhibiting the present variety of folks inside and their entry/exit statuses.

Disclaimer

This mission is designed for academic functions. For real-world deployment, please guarantee correct safety measures are taken, particularly with delicate information corresponding to RFID tags linked to non-public data. Use a take a look at setup with restricted funds or dummy information for verification earlier than full implementation.

Code for IoT Entry and Exit Monitoring System

Clarification

1. Libraries and Definitions: Contains obligatory libraries for SPI, RFID communication, and net server functionalities. Defines pin assignments and person information.
2. Setup Operate: Initializes serial communication, SPI, MFRC522, and Wi-Fi. Units up net server routes for the foundation URL and attendance web page.
3. Loop Operate: Constantly checks for brand spanking new RFID playing cards. Reads the UID, compares it to saved UIDs, and updates attendance information. If an RFID card matches, it updates the punch-in or punch-out time and sends an replace message to the server.
4. Internet Server Handlers:
   • handleRoot(): Serves a easy HTML web page with a hyperlink to view attendance.
   • handleAttendance(): Serves an HTML web page with a desk displaying the attendance information. CSS types are used to format the desk for higher readability.
5. getTime(): Supplies the present date and time within the format “YYYY-MM-DD HH:MM

IoT primarily based Entry and Exit Monitoring System – Circuit Connection

Now join the RFID to SPI pins of the INDUSBoard Coin as per circuit diagram.

Testing

1. Add the Code: Use the Arduino IDE to add the code to your IndusBoard Coin
2. Connect with Wi-Fi: Make sure the ESP32 is related to the Wi-Fi community.
3. Entry Internet Server: Open an online browser and navigate to the IP deal with of the ESP32. It is best to see a web page with a hyperlink to view attendance information.
4. Scan RFID Playing cards: Check scanning the RFID playing cards and confirm that the attendance information are up to date accurately on the internet web page.
5. Actual-Time Updates: Refresh the attendance web page to see real-time updates as you scan completely different RFID playing cards.

This mission gives a sensible introduction to IoT, net improvement, and RFID know-how, permitting you to construct a real-time attendance system with a contemporary net interface.
