M256 isina kutonhorera yekupisa yekufungidzira module
♦ Nhanganyaya
Thermal imaging module yakavakirwa paceramic packaging isina kunyungudutswa vanadium oxide infrared detector kuti igadzire yakakwira infrared thermal imaging zvigadzirwa, zvigadzirwa zvinotora parallel dijitari inobuda interface, interface yakapfuma, inogadzirisa kuwana kwakasiyana kwehungwaru yekugadzirisa chikuva, ine hunyanzvi hwekuita uye simba rakaderera. kushandiswa, vhoriyamu diki, nyore kune hunhu hwekubatanidzwa kwekusimudzira, inogona kusangana nekushandiswa kwemhando dzakasiyana dze infrared yekuyera tembiricha yekudiwa kwechipiri kusimudzira.
Product features
- Chigadzirwa chacho chiduku muhukuru uye nyore kubatanidza;
- FPC interface inogamuchirwa, iyo yakapfuma mumafayilo uye iri nyore kubatana nemamwe mapuratifomu;
- Kuderedza simba rekushandisa;
- High image quality;
- Kuyera kwekushisa kwakarurama;
- yakajairika data interface, inotsigira sekondari kusimudzira, nyore kusanganisa, inotsigira kuwana kune akasiyana ehungwaru kugadzirisa chikuva.
