qhia me ntsis

Qee lub sijhawm dhau los, Kuv pom lub ntsuas ntsuas lub plawv ntsuas MAX30100 hauv khw hauv online. Cov qauv no tuaj yeem khaws cov pa oxygen thiab cov ntaub ntawv ntsuas lub plawv ntawm cov neeg siv, uas kuj yog qhov yooj yim thiab yooj yim siv. Raws li cov ntaub ntawv, Kuv pom tias muaj cov tsev qiv ntawv ntawm MAX30100 hauv Arduino cov tsev qiv ntawv cov ntaub ntawv. Ntawd yog hais, yog tias kuv siv kev sib txuas lus ntawm Arduino thiab MAX30100, Kuv tuaj yeem hu ncaj qha rau Arduino cov tsev qiv ntawv cov ntaub ntawv yam tsis tas yuav rov sau cov ntaub ntawv tsav tsheb. Qhov no yog qhov zoo, yog li kuv yuav qhov qauv ntawm MAX30100.
