IR (infrared) camera modules are devices that capture images by detecting infrared light, which is invisible to the human eye. These modules are especially useful for imaging in dark environments or low-light conditions. Infrared light allows detection based on heat emitted from objects or reflected IR radiation.

IR cameras are used in a wide range of fields, including security systems, robotics, industrial inspection, and certain medical imaging applications.

Typically compact in design, IR camera modules are built to be easily integrated into various electronic projects.

In conclusion, IR camera modules offer a powerful imaging and sensing solution by making the invisible things visible in many different applications.
