Niaj hnub no muaj ntau txoj hauv kev xaiv cov nyees khawm thiab cov cuab yeej hloov pauv ntawm tus nqi thiab txhua yam ntawv. Hmoov tsis zoo, yog tias koj tab tom nrhiav kom tau cov tswv yim analog, koj cov kev xaiv muaj ntau qhov txwv. Yog tias lub tshuab hluav taws xob muaj peev xwm tsis ua tau raws li qhov koj xav tau, koj yuav muaj hmoo.

Kuv tau teeb tsa los tsim cov cuab yeej siv suab paj nruag uas tuaj yeem txheeb xyuas qhov nyuaj ntawm tus neeg siv nias lub pob, txuas ntxiv. Piezzoelectric sensors tau tawm ntawm cov lus nug, vim tias thaum lawv tuaj yeem muab nyeem tau nyuaj npaum li cas koj nias, nws nyuaj rau khaws cov ntawv nyeem kom raug rau ntau vib nas this. Flex sensors tau kim thiab tsis zoo.

Velostat, uas yog ib lub npe ntawm piezzo-resistive yas (ntau dua koj nias, qis dua nws cov hluav taws xob tsis kam) haum daim nqi kom zoo. Hnub no, Kuv yuav taug kev koj los ntawm cov pov thawj-ntawm-lub tswv yim, thiab cov qauv zoo. Qhov tom kawg ua haujlwm tau zoo ntseeg tau tom qab ntsuas, thiab yooj yim thiab pheej yig txaus uas koj yuav txiav txim siab ua los ntawm kaum ob.

Siv ib daim duab los qhia thiab ib tus cwj mem cwj mem coj los, kos tus qauv sib xyaw ua ke. Kuv txoj kab yog hais txog 2mm dav thiab 1mm hla. Tom qab ntawd kuv txiav ib daim 15*15mm ntawm velostat uas kuv tso rau saum.

Thaum nias nrog kuv tus ntiv tes, Kuv tuaj yeem ntsuas qhov tsis kam nruab nrab ntawm 5 thiab 15 kOhm, nyob ntawm qhov nyuaj kuv nias.

Kuv tsim PCB Circuit Court rau kuv qhov project thiab tau ua haujlwm zoo. Ntawm qhov piv txwv no, txoj kab yog 0.5 hli dav thiab 0.5 hli sib nrug; tab sis Velostat yog qhov tseeb zam txim ntau.

Kom tau txais txiaj ntsig zoo, tso Velostat tsuas yog qhov uas koj xav tau. Kuv punched 5mm-dimeter daim, thiab kaw lawv nrog kab xev tsis tu ncua. Z-axis cov kab xev tsis ua haujlwm ntawm no, vim nws tso tawm qeeb heev, thiab koj tsis tuaj yeem qhia thaum tus neeg siv tau tsa nws tus ntiv tes.

Kuv siv cov nyees khawm silicon kuv xaj los ntawm Taobao (tab sis yog tias koj tsis nyob hauv Suav teb, koj yuav muaj hmoov zoo dua rau koj li ib txwm khoom siv hluav taws xob). Lawv yog 10 hli txoj kab uas hla, (12 ntawm lub hauv paus), thiab tsis muaj lub ncoo coj los hauv qab.

Lub hauv paus yog li 1 hli tuab, uas nyob ze rau qhov tuab ntawm ob daim kab xev uas kuv tau dag ib ncig.

Txhawm rau xaum lub qhov hauv daim kab xev ob tog, koj yuav tsum tso nws tiaj; kom nws tsis txhob lo rau ntawm koj lub rooj, siv ib daim ntawm cov ntawv lo lo lo lo lo lo lo lo, uas zoo li zaj duab xis tiv thaiv ntawm koj yob ntawm ob daim kab xev, thiab lo rau hauv qab. Kuv pom kuv cov punches ntawm Taobao, rau tsawg dua ib daus las ib thooj.

Nyob rau sab saum toj ntawm daim kab xev ob sab, kuv tso ib daim yas los ntawm lub hau npog uas siv los sau ntawv.

Tom qab sib dhos lub pob, Kuv muab kuv tus ntiv tes tso rau saum, thiab ntsuas qhov ntsuas ntawm 1.5 txog 18 kOhm. Yog tias koj tsa koj tus ntiv tes, Velostat yuav kov lossis tsis tau, yog li cicuit qee zaum qhib.

Txhawm rau siv lub pob tshiab no, teeb tsa tus choj faib hluav taws xob nrog tus tiv thaiv (hais, 4kOhm). Qhov nruab nrab taw tes tuaj yeem ntsuas nrog Arduino.

Tom qab ntawd koj yuav tsum ntsuas ntsuas qhov tsawg kawg thiab siab tshaj plaws, thiab xam seb koj nyob deb ntawm ob. Kuv muaj peev xwm tau txais 7- lossis 8-ntsis cov lus teb tawm ntawm 10-ntsis Atmega analog cov tswv yim yam tsis muaj kev cuam tshuam ntau dhau.

Cov lus teb nkhaus tsis yog tawm. Kuv tseem tsis tau sim ua kom zoo li qub. Tsis tas li, muaj qee qhov hysteresis: tus nqi koj rov qab los tom qab tso lub pob feem ntau txawv me ntsis ntawm qhov koj tau ua ntej nias. Txawm li cas los xij, thaum siv nws nrog tib neeg cov ntiv tes, nws twb zoo txaus rau suab khoov thiab vibratos.
