NTE30116 Tinted Blue 5mm Infrared LED Emitter (940nm) SM0038 Photo Module for PCM Remote Control System (38kHz) The principle of this setup is somewhat simple and self-explanatory. In this circuit, ...

The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide. Potentiometer tuning was a fiddly affair, but ...

When a finger or other object touches the surface, it causes the IR light to scatter in many directions. Some of this light is directed down into the screen, towards an array of 64 IR sensors.

Krejci’s design, while affordable, offers an 8×8 resolution, which is the maximum output of the AMG8833 infrared sensor array. DIY Arduino thermal camera Watch this video on YouTube.
