Abstract
The heat irradiated by a surface depends on its temperature, colour, and roughness. In this manuscript, we built a 3D-printed rotary platform to monitor the radiation emitted by different surfaces and their temperatures. Instead of using a cube, we used a can with four regions (black, white, shiny, and matt surfaces). An Arduino board is responsible for controlling a step motor that rotates the can and collects simultaneous data from an infrared sensor module and a thermometer. With this apparatus, the students can observe the infrared radiation intensity as a function of the surface.
