Cheap Arduino-based Thermal Flashlight
Thermal flashlight is a widely used technique to “paint temperature with light”: by using a temperature sensor and a RGB flashlight, it is possible to illuminate a surface with a proper tonality, which, in turn, can be acquired by means of a standard camera. It’s main use is to find thermal leaks in houses and buildings.
In their article, PLOTS‘ staff propose and describe a nice and cheap way to build your own thermal flashlight with Arduino, together with a clear introduction to the subject.
