Paper Abstract

There is a set of sensing devices for a cloud on sky detection. The common passive examinations of cloud presence are realized with digital post processing of picture that was taken with fish eye lenses. Therefore, results of examinations are delayed and information at skyline is degraded. The common examinations include also thermal image analysis or the active laser distant sensors adaptations. The common feature of these sensors is the high cost of equipment. Thus, sensing device constructions for real-time measurements of clouds taking place on the skyline have been examined. Examinations were performed at the same time with two sensing devices that include two different optical channels. The first sensing device, used as a laboratory reference, consists of two spectrometers Maya 2000 pro while mechanic module consists of a plate with large core optical fiber adapter and fiber optic collimator adapter. These adapters are used to fix collimator and an optical fiber that is connected to a proper spectrometer. The examination results enable to point relation of variation of cloud cover factor as variation in semi-stable band 440 nm and variation in an unstable band that extends to longer than 550 nm wavelengths. Therefore, the second device, aimed as a cost effective consist of two optoelectronic sensors type BH1750 and OPT101 that are connected by a mechanical adapter that includes optical filters to binoculars. These optical filters are 440 nm band pass and 550 nm long pass. The data obtained of examinations show that the second construction may be a base for further development of data processing algorithms for passive sensing device for a cloud on the skyline detection.
