The collaboration went wonderfully! The task was clearly formulated, the client was prompt in communication and quickly provided the necessary information for the work. During the implementation process, there were no misunderstandings — the communication was responsible and constructive.

It is pleasant to work with a technically savvy person who knows what they want from the project.

It is necessary to create an access control system for equipment.

The system consists of:

esp32 microcontroller
relay
RFID card scanner

Required functionality:

upon activation, the system opens the relay contacts and waits for input from the card scanner in Wiegand format
when scanning a card, if access is granted, it closes the relay for 30 seconds
after granting access, the system measures the time of equipment usage by the user
in the background, at a set interval, the system checks WiFi availability and, if detected, connects and updates the user database, as well as sends logs to the mqtt server.
configuration of all parameters should be provided through a web interface
provide the possibility of connecting card scanners of another type
