Smart Attendance System

By Elina Levi and Arad Reder

Project Description

This Smart Attendance System (or SAS) is used to monitor the comings and goings of users from a certain area. The users can sign themselves up to the system by scanning an RFID tag and inputting a valid ID. After signing up, a request for approval is sent to a Google Sheet doc accessible by a manager. If the manager approves a user, the user can scan his RFID tag upon entering and / or exiting said area. Each such scan is then logged locally on the device and sent to a different sheet in the same doc as the sign up sheet.

Arduino/ESP32 Libraries

• robtillaart/I2CKeyPad - v0.3.3
• miguelbalboa/MFRC522 - v1.4.10
• adafruit/Adafruit SSD1306 - v2.5.7
• bblanchon/ArduinoJson - v6.21.3

Folder Descriptions

• ESP32: source code for the esp side (firmware).
• GoogleAppScript: source code for the backend (Google App Script is used to handle POST requests sent from the ESP).
• Documentation: wiring diagram.
• Unit Tests: tests for individual hardware components (input / output devices).
• Parameters: contains a softlink to "consts.h", which contains all configurable parameters.
