The topic of this diploma work is design and realization of an outdoor device for measuring correlated colour temperature of light in five directions of the sky. The device is based on use of TCS230 sensors and Raspberry Pi computer.
This work describes: design and construction of the device, realization of measuring part with sensors and electronics box, working principles of the software written for this application and data conversion. Designing of a shadow ring for reducing the effect of direct sunlight is also described.
Some initial problems with device operation and solutions to this problems, as well as some initial raw measurements are presented at the end.
