ABSTRACT
A dedicated device for collect, store and record data from various sensors and the photovoltaic generator itself over the time is presented in this paper. The device is designed and developed for the laboratory of Renewable Energy of FTS needs, intended for laboratory testing of the influence of meteorological and electrical conditions on the efficiency of photovoltaic panel as the panel temperature, air humidity, air pressure, solar radiation, wind speed, wind direction, voltage and current. The designed data logger prototype is based on the microcontroller (MCU) STM32F411 for sensor processing data, while for data store and recording is used portable storage device - SD card. The MCU’s internall Real Time Clock (RTC) was implemented to record date and time, as administrative data, during an acquisition. For storage and for recording acquired data the memory of Bluetooth enabled android mobile phone can be used also and with installed free application Serial Bluetooth Terminal. Namely, the data logger is equipped with Bluetooth transceiver for remotely monitoring of acquisition in the real time. The sampling time of the device is variable and can be adjusted during an acquisition using the phone application. The default value is 1000 ms. Mentioned application provides the Bluetooth connection terminal, data display terminal and data storage facility on a mobile phone.
The results obtained by recording data over a longer time interval, which are stored on the SD card in file form, will be used for various software analyzes and modeling the effect of the inclination angle on the efficiency of photovoltaic modules.
