Jagorar Mai Amfani da Kyamarar MLX90640-D110 IR Array Thermal Hoto Mai Zafi

1. Gabatarwa

Wannan littafin jagora yana ba da cikakken umarni game da kyamarar daukar hoto ta MLX90640-D110 IR Array Thermal Imaging Camera. An tsara wannan tsarin don ma'aunin zafin jiki mara hulɗa da aikace-aikacen daukar hoto ta thermal, wanda ya dace da nau'ikan microcontrollers daban-daban kamar Raspberry Pi, ESP32, da STM32.

MLX90640-D110 yana amfani da tsarin firikwensin zafi mai nisa-infrared don gano rarrabawar IR, canza bayanai zuwa yanayin zafi na saman, da kuma samar da hotunan zafi. Girman sa mai ƙanƙanta yana ba da damar haɗawa cikin tsarin sarrafawa na masana'antu da fasaha.
