The sensor can be pointed at an object, and the Arduino can sense the brightness of that one point. Since this camera compiles an image so slowly, it sometimes has a problem with varying brightness.

Krejci’s tutorial video guides viewers on how to construct an infrared camera using an Arduino UNO, an infrared sensor AMG8833, and an 8×8 RGB LED display from SunFounder. Thermal cameras are ...

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.

Arduino enthusiasts may be interested in a new single pixel scanning camera which is powered by an Arduino Uno combined with a TCS34725 sensor available from online stores such as Adafruit.
