چکیده :

With the rapid expansion of photovoltaic systems in modern power networks and renewable-powered telecommunication sites, accurate and continuous monitoring of environmental and electrical parameters has become essential. This paper presents the design and development of a web-based, multi-parameter data logger using an ESP32 microcontroller for real-time monitoring of solar panels. The system integrates sensors for ambient temperature and humidity (DHT11), precise panel temperature (NTC10K), solar irradiance, wind speed, and DC voltage and current, sampled at 10-second intervals. Data are transmitted via Wi-Fi to a MySQL database and visualized through an interactive dashboard developed using HTML, CSS, JavaScript, and PHP. The dashboard supports real-time charts, calendar-based time filtering, and Excel data export, enabling comprehensive analysis without external cloud platforms. Field testing demonstrates the system’s accuracy, stability, and ability to capture rapid environmental changes that influence PV performance. Compared to existing low-cost monitoring solutions, the proposed logger offers higher measurement resolution, broader sensing coverage, and more advanced web-based analytics, making it suitable for research, PV plants, and renewable-powered telecom infrastructure.
