Hauv tsab xov xwm hnub no kuv xav qhia rau koj txog qhov project tshiab. Lub sijhawm no nws yog qhov kov hloov nrog lub iav vaj huam sib luag. Cov cuab yeej yog compact, ntsuas 42x42mm (tus qauv iav panels muaj qhov ntev 80x80mm). Keeb kwm ntawm cov cuab yeej no tau pib ntev dhau los, txog ib xyoos dhau los.
Thawj qhov kev xaiv tau nyob ntawm atmega328 microcontroller, tab sis thaum kawg nws tag nrho xaus nrog nRF52832 microcontroller.
Qhov kov ntawm lub cuab yeej khiav ntawm TTP223 chips. Ob lub sensors tau txais kev pabcuam los ntawm ib qho cuam tshuam. Tsim los ntawm lub roj teeb CR2477, ntawm lub zog hloov pauv ntawm TPS610981 nti | .
Cov cuab yeej siv hluav taws xob tawm hluav taws xob siv hluav taws xob cuam tshuam los ntawm transistors. Tom qab nias lub pob, lub microcontroller nws tus kheej cuam tshuam kev tswj fais fab thiab tom qab ntawd lub pob tuaj yeem siv rau cov kev pabcuam (hauv kuv rooj plaub, qhov no yog ua ke nrog lwm cov khoom siv, tua lub zog thiab rov pib dua rau lub Hoobkas chaw).
Muaj 2 rgb LEDs rau kev qhia lub xeev thiab kev pabcuam hom. Lub piezo emitter kuj tau ntxiv los simulate nias thaum kov cov khawm kov thiab lub suab qhia txog kev pabcuam hom. Cov LEDs thiab piezo emitter tuaj yeem qhib thiab tawm ntawm tus neeg siv qhov kev txiav txim siab. Qhov no yog ua tiav los ntawm kev tswj hwm lub tsev ntse los ntawm kev xa cov lus txib mus rau cov khoom siv sensors; tus neeg siv kuj tuaj yeem hloov lub sijhawm xa cov roj teeb thiab cov teeb liab theem kuj los ntawm tus tswj tsev ntse. Hauv kuv qhov xwm txheej nws yog .
Kev noj nyob rau hauv hom kis yog 7mA (250kbit, 10ms), noj nyob rau hauv pw tsaug zog yog 40Β΅A, noj nyob rau hauv lub off-lub xeev yog tsawg tshaj li 1Β΅A (= noj ntawm lub boost converter nyob rau hauv "tsis ua hauj lwm" hom). Rx, tx, swd connector rau programming yog muab. Ib qho me me 2x3p txuas nrog lub suab ntawm 1.27 yog siv. Ib lub adapter tshwj xeeb yog tsim rau kev ua haujlwm.
Raws li ib txwm muaj, kev ua haujlwm ntawm lub cuab yeej yog raws li txoj cai . Qhov kev hloov pauv no yog npaj los siv rau hauv cov menyuam qhov muag tsis pom kev tswj qhov system. Tab sis feem ntau, daim ntawv thov tsuas yog txwv los ntawm koj lub tswv yim. Piv txwv li, kuv tus tub (7 xyoo) twb tau ua 3 qhov kev txiav txim rau kev hloov pauv: qhib thiab tawm lub teeb hauv chav dej nrog lub dab da dej (nws yuav tsum tau muab tso rau hauv pem teb), tig lub teeb nyob rau hauv ib qho chaw da dej. Txoj kev ntev thiab tsaus ntuj thaum mus rau hauv chav dej nrog lub dab da dej, thiab lwm qhov ua rau ntawm txaj, kom ceev ceev tig lub teeb hauv koj chav kom cov dab khiav tawm.
Cov ntaub ntawv yog ib txwm luam tawm ntawm lub tshuab luam ntawv SLA, cov cuab yeej yog qhov me me, cov ntaub ntawv hloov mus rau me me, kev siv tshuab luam ntawv no yog qhov ncaj ncees.
Saib cov qauv luam tawm
Cov hlau nplaum yog glued rau hauv rooj plaub thiab lub roj teeb compartment cover.
Cov yeeb yaj kiab nrog kev sim ntawm cov cuab yeej no:
Rau cov neeg uas xav rov ua dua:
