This research paper presents a project to create a device for complex measurement of atmospheric parameters affecting the operation of a solar cell, based on the Arduino microcontroller. The purpose of the study is to develop a device capable of measuring illumination, temperature, humidity and wind speed to assess their impact on the efficiency of solar panels. The research paper describes the necessary components for assembling the device, such as a BH1750 light sensor, a DHT22 temperature and humidity sensor, a Grove anemometer and an LCD display. A diagram of how to connect the components to the Arduino Uno microcontroller is provided, as well as an example of software code for collecting and displaying data. The results of the study include an analysis of the collected data to calculate the efficiency of the solar cell under various atmospheric conditions. Methods for correcting the data taking into account temperature changes and the cooling effect of the wind are considered. In conclusion, the possibilities for further improvement of the device are discussed, including anemometer calibration, integration with Internet services for remote monitoring, and adding a data storage function. The developed device can be used to optimize the operation of solar panels, as well as in research and educational projects aimed at studying the influence of external factors on the performance of solar cells.
