The MLX90640-D55 Thermal Camera is a small size, non-contact and low cost IR array thermal imaging camera with 32×24 pixels. It detects the IR distribution of objects in the field of view, converts the data to the surface temperature of the objects through calculation, and then generates thermal images for easy integration into a variety of industrial or intelligent control applications.
