Abstract
This thesis is toward to creating of workplace for evaluation of atmospheric effects on optical atmospheric link
In theoretical part of thesis is described the principle of working Free Space Optics (FSO), technology overview, the factors affecting FSO link, such as attenuation caused by atmosphere, and weather influence.
The practical part includes the creation of workplace, for evaluation what kind of influence has weather on Received Signal Strength Indicator (RSSI) values. For this reason, I created small meteo station which is installed on the roof of building N, in university campus. In meteo station are used sensors for measuring air temperature, humidity, barometric pressure, wind speed and wind direction. All these sensors are connected to Arduino mega 2560 and accordingly to Raspberry Pi, which sends data to web server www.samsungsami.io. Data on web page is displayed in graphs, where we can manipulate with date and time in order to get desirable data.
