You have to carefully look at [upir’s] Arduino thermal camera project because it intersperses pictures of what you expect an 8×8 sensor will produce with images produced by a much better camera.

The resulting ‘Raspberry Pi Camera Module 3 Sensor Assembly’ measures 10.8 x 10.8mm plus the connecting flexy. Inside, its die is the 4,608 x 2,592 (11.9Mpixel) Sony IMX708, which has 1.40μm pixels, a ...

The Arduino monitors the battery level and indicates its charge on the RGB status LED. The Arduino can also trigger the camera’s shutter using an NPN transistor and 2.5mm 3 pole jack.” ...

The Raspberry Pi compute module is a powerful piece of hardware, especially for the price. With it, you get more IO than a normal Pi, plus the ability to design hardware around it that’s spec… ...
