Arduino PCAS
Budget: $10 – $30 USD
It is necessary to develop Arduino software to send requests when bringing an NFC card to the reader and when processing the received response (true/false) to open/close the door.
Hardware:
ESP-WROOM-32 Dev Module
NFC Reader PN532
You also need to save the database (~5000 UID with access status) to the device once a day.
The server part has already been developed and is ready for operation.
