Abstract
Effective management of electrical energy requires monitoring, controlling, and storing parameters gathered from power measurement devices including voltage, current, and power factor. This assessment of the quality of electrical energy is essential for management organizations, power companies, and individual consumers to develop efficient electricity usage plans. In this paper, we propose a hardware implementation for data collection and online communication software integrated with a system for collecting data on consumption of electrical energy. The EM115-Mod CT multifunction industrial meters by the FINECO, the KLEA 220P three-phase multifunction meter by the KLEMSAN, and the ME96SS–ver.B by MITSUBISHI are firstly utilized. Finally, the collected data of voltage, current, electrical consumption, temperature, and humidity can be stored on the SD card and transmitted to the cloud for real-time monitoring on mobile devices facilitated by the ESP-WROOM-32 microcontroller from the Espressif system. The obtained results showed that the temperature and the humidity changed gradually with time and remained within the standard range of temperature and relative humidity.
