Yuav ua li cas ntxiv qhov hloov pauv kov tau rau koj cov haujlwm hauv tsev

Nyob zoo cov phooj ywg hluav taws xob diy hauv qhov kev qhia no kuv yuav qhia koj li cas koj tuaj yeem ntxiv qhov hloov pauv tau rau koj cov phiaj xwm hluav taws xob kom pheej yig, thiab muab koj li phiaj xwm diy ua haujlwm zoo thiab ua haujlwm tau yooj yim dua ib kauj ruam.

Kauj Ruam 1: Dab Tsi Yog Kov Hloov

Dab Tsi Yog Kov Hloov

Kev hloov pauv yog hom hloov pauv uas tsuas yog yuav tsum tau kov los ntawm ib qho khoom siv los ua haujlwm. Nws tau siv rau hauv ntau lub teeb thiab cov phab ntsa hloov pauv uas muaj cov hlau sab nrauv ntxiv rau hauv cov chaw siv computer. Lub vijtsam kov suav nrog ib qho ntawm cov hloov pauv ntawm lub vijtsam. Qhov hloov mus kov yog qhov yooj yim tshaj plaws ntawm cov cuab yeej tactile. Qhov kev hloov pauv no yuav hloov sai dua lossis tom qab qhov kev sib cuag qub, txhua yam khoom siv hluav taws xob niaj hnub tuaj nrog qhov hloov pauv no, zoo li lub tshuab hluav taws xob qub yuav raug hloov nrog mosfet transistor sai sai no

Lub peev xwm hloov pauv yog lub peev xwm hloov pauv

Kev hloov pauv lub peev xwm xav tau tsuas yog ib qho hluav taws xob los ua haujlwm. Cov hluav taws xob tuaj yeem tso rau tom qab lub vaj huam sib luag uas tsis muaj hluav taws xob xws li ntoo, iav, lossis yas. Qhov hloov pauv ua haujlwm siv lub peev xwm ntawm lub cev, cov cuab yeej ntawm tib neeg lub cev uas muab nws cov yam ntxwv hluav taws xob zoo. Qhov hloov pauv ua kom them nyiaj thiab tawm nws cov hlau sab nrauv txhawm rau txheeb xyuas kev hloov pauv ntawm lub peev xwm. Thaum ib tus neeg kov nws, lawv lub cev ua rau lub peev xwm nce ntxiv thiab ua rau qhov hloov pauv. Cov peev txheej hloov pauv tau muaj kev lag luam raws li kev sib txuas ntawm cov tuam txhab tsim khoom. Cov cuab yeej no tseem tuaj yeem siv ua qhov ntsuas qhov sib nrug deb.

Txhawm rau ua (sib sau ua ke) thiab muab tso ua ke qhov hloov pauv lub peev xwm/lub peev xwm no peb yuav xav tau cov khoom siv hauv qab no thiab pawg thawj coj loj uas pheej yig heev thiab muaj txiaj ntsig, thiab yav tom ntej cov haujlwm peb yuav ua qee qhov kev hloov pauv

ua kom nws tsis hloov, latch rau/latch tawm thiab ntau dua

-Phom phom phom

-Muag khoom

-Flux

-Cov xov hlau

-powerbank

-capacitive module board

Txoj haujlwm yog nyob ib puag ncig puag ncig lub khawm khawm uas muaj peev xwm uas pheej yig, me thiab ntseeg tau thiab zoo li qub, tsis muaj lus piav qhia ntawm lub vev xaib.so peb yuav tsum khawb hauv qee yam kom ua qhov no tshwm sim thiab rau koj kom rov ua dua hauv tsev tau yooj yim heev. Txhawm rau ua kom lub zog nti no koj yuav xav tau ntawm 3-5v thiab cov zis yuav tsum nyob hauv tib qhov kev piav qhia tag nrho

TTP capacitive sensor tshwj xeeb:

Kev siv hluav taws xob 2.0V ~ 5.5Vƒ Ua haujlwm tam sim no @VDD = 3V, tsis muaj thauj khoom, SLRFTB = 1, Thaum muaj lub zog qis hom 1.5uA, siab tshaj 3.0uA thiab Thaum nrawm hom raug 3.5uA, siab tshaj 7.0uA Ua haujlwm tam sim no @VDD = 3V, tsis muaj thauj khoom, SLRFTB = 0, Thaum qis zog hom 2.0uA, siab tshaj 4.0uA thiab Ntawm hom nrawm li 6.5uA, siab tshaj 13.0u xaiv hom los ntawm kev xaiv ncoo (LPMB tus pin) Kev Ua Haujlwm Kub: -20 ~ +70 ℃

TTP223 yog kov lub ntsuas phoo IC uas muaj 1 tus yuam sij kov. Kev kov lub ntsej muag IC tau tsim los txhawm rau hloov pauv ib txwm khawm qhov tseem ceeb nrog ntau yam ncoo loj. Kev siv hluav taws xob tsawg thiab kev siv hluav taws xob dav yog qhov sib txuas tseem ceeb rau DC lossis AC daim ntawv thov
