Abstract

Archive room security is essential to prevent potential threats such as fire and unauthorized access. This study aims to design and develop a prototype of an archive room security monitoring system based on the Internet of Things (IoT) using the ESP32 microcontroller, DHT11 temperature sensor, MQ-2 gas sensor, and PIR motion sensor, with the Blynk application as a real-time monitoring interface. The system was developed using the prototyping method, which includes stages of requirement gathering, design, prototype development, evaluation, and refinement. The test results indicate that the system successfully reads data from the three sensors accurately and transmits it to the Blynk application with an average response time of less than 2 seconds. Notifications are sent to the user’s device within 1–2 seconds after a hazardous condition is detected. The DHT11 sensor responds well to gradual temperature increases, the MQ-2 sensor triggers alerts when gas values exceed 400 ppm, and the PIR sensor effectively detects motion up to a distance of 4 meters. Additionally, the system operated stably within the local Wi-Fi range and continuously functioned for 8 hours without interruption. Future developments may include the integration of user identification features, automated responses, additional sensor types, and the development of a custom monitoring application. Keywords: Internet of Things (IoT), Archive Security, ESP32, Blynk, DHT11 Sensor, MQ-2, PIR.
