Smart Attendance System: An Internet of Things (IoT)-Enabled Concept

Schools and colleges must effectively handle attendance data to ensure the attendance of all students. We created a portable smart attendance system (SAS) to solve typical problems with conventional attendance systems, such as their inadequacy for dynamic educational situations, susceptibility to mistakes, and time consumption. SAS creates a reliable and effective biometric attendance solution by combining complex components such as the ESP32 microcontroller, R307 fingerprint sensor, and 11.44-inch thin-film transistor organic light-emitting diode display. SAS provides a reliable and efficient means of documenting attendance by using fingerprint biometrics for personal identity and authorization. The R307 sensor accurately scans and validates student fingerprints, while the ESP32 microcontroller analyzes verified attendance data. This data is then saved on a XAMPP server via the internet of things. Furthermore, SAS interacts with Twilio, allowing teachers to send attendance information to parents via SMS. This strategy enhances communication between educational institutions and parents, ensuring early notifications and enabling quick responses to irregular attendance. The suggested approach was field-tested with 20 students for 7 days and achieved a 100% accuracy rate.
