Hotel lock system with ESP32
Budget: $250 – $750 USD
Hotel lock system
My intention is to make an electronic hotel lock system, where the lock itself does NOT connect to the internet.
The user will scan a Qr code at the door, and the door will open if the user has access rights.
This is how; the Qr code contains the URL to an ESP32 inside the lock. That reads the lock number. The number of the lock is sent to a server, using the mobile phone's Internet connection (also the phone number). The server calculates an electronic key as a response and the phone sends that response to the ESP32.
The ESP32 decrypts the message. If the message contains the lock number and a date/time that is higher than the then last attempt to open the door, to lock opens.
The system needs encryption from the use of primes.
ESP32 coding
PHP, without UI, only DB access.
Code for Ionic Angular platform
