IMPLEMENTASI SISTEM PRESENSI BERBASIS IOT (INTERNET OF THINGS) MENGGUNAKAN PLATFORM BLYNK DI SMK CENDIKIA RANCAKALONG

Abstract

An IoT (Internet of Things) based attendance system using the Blynk Platform with NodeMCU and ESP32-CAM is a teacher attendance management and monitoring system. This system combines Radio Frequency Identification (RFID) technology for time and attendance detection, NodeMCU and ESP32-CAM microcontroller hardware for data processing, and a MySQL database for storage and management of time and attendance data. Using an RFID card, teachers can easily record attendance via a reader connected to the NodeMCU, and the ESP32-CAM provides the ability to capture facial images as an additional verification step. Attendance data is stored in a MySQL database in a structured manner, enabling efficient data management and accurate attendance reporting.
