Abstract

In an era where technological advancements drive improvements across varioussectors, enhancing efficiency in educational management systems is crucial. This paperpresents a novel wireless attendance system that leverages the Espressif wireless networkover Wi-Fi (ESP-NOW) protocol, which offers advantages over traditional wireless fidelity(Wi-Fi) by enabling low-power, low-latency, and direct device-to-device communicationwithout the need for an intermediary network. The system employs ESP32 modules con-figured as both slave and master devices. Slave devices, positioned on the lecturer’s desk,interact with students’ smartphones when the lecturer initiates the class, while master de-vices, strategically placed at multiple locations within the classroom, compile and consol-idate attendance data for each room. The system incorporates Received Signal StrengthIndicator (RSSI) based restrictions via the ESP-NOW protocol to prevent overlapping at-tendance between rooms and ensure that students can only record their presence if theyare physically within the designated classroom. Attendance data is automatically loggedand made accessible in real-time through a dedicated mobile application for lecturers. Em-pirical testing shows exceptional accuracy in attendance recording, with no packet lossobserved during trials, an average verification time of less than 1 second, and a data trans-mission rate consistently ranging from 700 to 800 Bytes/seconds. This paper highlightsthe system’s potential for reliable and efficient attendance tracking and identifies future improvements, including expanded coverage and data security features.
