Did you have some spare Arduino that being stored for a long time inside the storeroom? If you can spend few hours in the weekend, then you might be interested to build up a marvelous yet cheap Thermoscanner.
The definition “Thermoscanner” is actually the short form of “Thermography scanner”. Oh, talking about thermography, would you like to know more about it?
Technically, thermography or thermal imaging is a type of infrared imaging science. In most of the time, thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum and produce images of the radiation. We called the outcome as “thermograms”.
Infrared radiation is emitted by all objects based on their temperatures and makes it possible to see one’s environment with or without visible illumination, even at the darkest places during night! The Thermographic cameras are good on spotting the warm objects, including humans and other warm-blooded animals become easily visible against the environment, especially on night!
By the way, this homemade Thermoscanner is extremely a piece of cake. Just mount a TPA81 thermopile array onto an XY servo mount and hook it up to the computer using the Arduino microcontroller. That’s it!
By less than $150, this Thermoscanner is considerably cheap compare with others in the marketplace.
