Tej zaum tsis yog. Cov khoom siv Raspberry Pi raug cai siv cov thawj coj ua haujlwm, thaum ultra- cov kev xaiv pheej yig yuav suav nrog cov rooj sib tw knockoff tsis muaj kev txhawb nqa thiab ntawv pov thawj. Cov clones no feem ntau muaj teeb meem kev ntseeg siab thiab incompatibilities nrog cov qauv qhia. Rau cov khoom, cov sensors pheej yig yuav ua haujlwm pib tab sis xa cov neeg tsis zoo lossis ua tsis tau sai. Qhov $ 20-30 tau txais kev cawmdim ntawm cov khoom siv clone tsis tshua pom qhov kev ntxhov siab thiab qhov ua tsis tiav.
Raspberry Pi cov khoom siv ua haujlwm muab cov txheej txheem nkag mus rau hauv ib qho - pawg thawj coj saib, ua lag luam tus nqi qis qis rau kev txuag sij hawm ntau thiab txo kev ntxhov siab. Rau cov neeg tuaj tshiab, kev yuav khoom sib sau ua ke, kev pov hwm kev sib raug zoo ntawm cov khoom, thiab cov ntaub ntawv qhia kev kawm pom zoo rau kev xaiv cov khoom siv los ntawm cov khoom siv ntawm tus kheej. Lub ntsiab lus yog nyob rau hauv kev xaiv cov khoom siv txuam nrog koj qhov kev nyiam tiag tiag thiab qib kev txawj es tsis yog lub hom phiaj xav tau.
Lub platform qhib ecosystem kom ntseeg tau tias koj yuav tsis muaj kev nqis peev ntau dua - cov txuj ci hloov pauv ncaj qha los ntawm cov khoom siv nyiam mus rau kev ua haujlwm tshaj lij, thiab kev txhawb nqa hauv zej zog tseem muaj zog thoob plaws qib kev paub. Pib nrog ib qho khoom siv tsom, ua kom tiav feem ntau ntawm nws cov haujlwm, tom qab ntawd nthuav dav raws li qhov kev xav pom thiab tsim kev txawj ntse.
