تصميم واختبار نظام فعال لحماية الألواح الشمسية من السرقة باستخدام تقنية IOT

Abstract

     In this research, a system was designed to protect solar panels from theft based on Internet of Things (IOT) technology. The designed system consists of two main components, the ESP32-CAM module, which is the heart of the system and its main control unit, and the MC-38 magnetic sensor. The designed system relied on the M2M (MQTT) communication protocol, in order to connect the control unit to the Internet with the NODE-RED platform that supports the MQTT communication protocol through the Adafruit IO server, as this platform provides many advantages related to the Internet of Things, which enables us to monitor the system in real time, and once the Internet is available, the system sends an alert in the form of a message, in addition to sequential images of the site, either via Gmail or the Telegram application on the mobile phone.

      We tested the designed system on the solar panels on the roof of the College of Engineering Technology. The results showed that the designed system is effective, economical (its cost was about $24) and has low energy consumption of 500 mWh. It also achieved very good protection for the solar panels installed on the roof of the college from theft due to its high response speed and performance, as it issues several types of alerts, audio alarm, sending an email or message, in addition to sequential images of the site on Gmail and the Telegram application in real time. The MQTT protocol also achieved great quality and high speed in sending messages, as the Wireshark program showed, through analyzing the network data by capturing the IP of the sent packet, a very low delay time for the arrival of messages, which is 66.559 [msec], and this average delay is considered "very good" according to the Tiphon classification, in addition to the packet loss of 5%, which is considered an average value according to the same classification.
