Nyob zoo txhua tus, Vam tias koj txhua tus ua tau zoo. Raws li tau hais ua ntej kuv yuav tsum tshaj tawm lub ntsuas kev noj qab haus huv hauv tsev hauv ib qho ntawm kuv cov lus qhia yav dhau los. Yog li ntawm no nws yog:

Wearable thev naus laus zis ua txoj haujlwm zoo ntawm kev khaws cov tab ntawm koj tus kheej lub cev. Tab sis txhawm rau ntsuas kev noj qab haus huv ntawm qhov chaw koj nyob, koj xav tau cov cuab yeej sib txawv. Cov cuab yeej no saib xyuas qhov ntsuas kub, av noo, suab nrov, thiab teeb pom kev zoo rau txhua chav thiab tseem tuaj yeem ua qhov ntsuas nkag, teeb nyem thiab them xov tooj thiab siv 1W LED txhawm rau tsim cov txiaj ntsig stroboscopic kom tau txais kev nkag mus. Tsis pub dhau lub casing, sau los ntawm cov ntsuas xa cov ntaub ntawv mus rau Arduino, uas txhais cov lus nkag thiab qhia cov ntaub ntawv ntawm lub vijtsam OLED me me. Raws li cov cuab yeej nyeem ntawv, koj tuaj yeem qhib lub tshuab ua kom lub cev qhuav dej, txo qhov ntsuas cua sov, lossis tawg qhib lub qhov rais-xijpeem nws yuav siv los ua kom koj lub tsev ib puag ncig xis nyob.

Cov cuab yeej no ua cov hauv qab no:-

1. Ntsuas thiab Zaub Kub (hauv *C lossis *F).
2. Ntsuas thiab Zaub Zaub (hauv %).
3. Xam thiab tso saib zoo li (Cov ntsuas cua sov) (hauv *C lossis *F).
4. Ntsuas thiab Zaub Suab (hauv dB).
5. Ntsuas thiab Zaub Teeb (hauv lux) (1 lux = 1 lumen/m^2).
6. Ntsuas thiab Zaub Zaub los ntawm ib yam khoom tshwj xeeb. (Hauv cm lossis nti).
7. Siv ua lub ntsuas ntsuas nkag (cais lub suab sib ntxiv tau ntxiv).
8. Siv los tsim cov txiaj ntsig stroboscopic.
9. Siv ua lub teeb nyem.
10. Them xov tooj thaum muaj xwm ceev.

Kuv xav hais txog tias cov lus qhia no tau tshaj tawm ntxov vim yog hnub kawg ntawm kev sib tw hnab tshos. Li no cov ntawv qhia tseem tsis tiav. Cov cuab yeej no tuaj yeem muab txhua qhov kev nyeem ntawv tab sis tseem tsis tuaj yeem siv ua lub tswb ntes thiab teeb nyem zoo li kuv tseem tab tom sau cov cai rau Tus Neeg Siv Kev Sib Tham (UI) nrog cov nyees khawm. Yog li thov pov npav rau kuv tsawg kawg hauv kev sib tw hnab tshos raws li kuv txuas ntxiv ua haujlwm rau cov cai thiab koj hais mav sib sau ua ke thiab pib ntsuas lub ntsuas. Tom qab ntawv koj tuaj yeem pov npav kuv hauv kev sib tw Arduino raws li koj xav tau (Yog tias koj nyiam txoj haujlwm).

Tsis tas li thov tsis txhob hla cov kauj ruam yog tias koj xav kom txoj haujlwm tsis muaj qhov yuam kev (ntau tus neeg hais txog kev ua haujlwm tsis yog thiab tsis tau teeb tsa Arduino cov tsev qiv ntawv kom raug rau teeb meem). Lossis koj tuaj yeem hla qee cov kauj ruam thawj ntawm kev ntsuas ntsuas thiab pib nrog mic thiab ntsuas lub teeb.
