Description

Schematic

The RC522 sensor is powered from a 5V pin of the Arduino UNO.
LM7809 supplies the constant 5V from an external source to the Arduino and Node MCU.
Two GPIO pins in Arduino are connected to the ESP 8266 for data communication.
If the RFID tag is read by the RC522 sensor, it sends a message to the Arduino and it turns sends the signal to the esp8266.
Message is transferred wirelessly to the respective Data Management system.
Here we used Google Sheet as a Management system that stores the messages in the sheet with respective time sessions.
In order to use this method, we must have an active internet connection to transfer data from esp8266 to sheets.
By this Method, we can record the Attendance of the student and manage it.
