DIY a COVID-19 NFC Mask Detector With Maduino Zero NFC

I made a DIY COVID-19 NFC Mask Detector, to ensure everyone who enters and exits the office to wearing a face mask. Using the Mauduino Zero NFC with the Arduino program.

Due to the impact of the coronavirus (COVID-19) epidemic, the office building strictly controls the entry and exit of staff. Everyone should wear a face mask and measure body temperature to enter.

 
During the COVID-19 period, Makerfans provide free face masks to employees, but some people don't always wear masks. That's why I made this project.
 
The staff must wear the NFC masks specially customized by Makerfabs, which cannot be accessed by outsiders. And we made a mask detector. If you wear an NFC mask, the door of the office building can be opened automatically. You can enter and exit freely, otherwise if you don't, you will not be able to enter.
 
Step 1: Prepare the hardware used in this project

Hardware:
Software:
  • Arduino IDE
Step 2: Wire Connect

L298N module -- Maduino Zero NFC
  • ENA -- D4 (GPIO4)
  • IN1 -- D5 (GPIO5)
  • IN2 -- D6 (GPIO6)
The electromagnetic lock is connected to L298N OUT2.
 
Step 3: Customized NFC Masks

Makerfabs made some customized NFC masks, nails sized NFC stickers attached, which supply free to employees.

Step 4: Install the NFC Mask Detector

The Maduino Zero NFC module is fixed on the door, and the NFC antenna is attached to the side of the door to detect whether the staff is wearing a mask.

Step 5: Testing
                       COVID-19-NFC-Mask-Detector-Testing
Staff wearing masks near the door, the instrument detecting if he/she is wearing a mask, if yes, the door opens automatically. (Also a few seconds later, the door will automatically close.)
 
Step 6. Codes
You can download the codes to complete by yourself.

As my friend said: "NFC-enabled masks is a fun idea! It serves the purpose of being an effective reminder without being overly complex or privacy-invasive."
If you have other fun ideas, let me know!
