Yuav ua li cas yuav ua rau ib tug tsab ntawv tsa suab sensor nrog koj ob txhais tes?

Tsab ntawv tsa suab sensors yog tam sim no muag nyob rau hauv yuav luag tag nrho cov khw ntawm lub tsev cov khoom siv. Tsab ntawv tsa suab sensor teeb pom kev zoo yog siv nyob rau hauv lub neej txhua hnub, xws li nyob rau hauv ib zaug li. Ntawm cov hoob kawm, koj mloog mus rau lub teeb, uas rau lub teeb li thaum koj txoj kev ua lawv? Qhov no yog ib cov piv txwv ntawm kev siv ntawm cov lus tsa suab detectors nyob rau hauv lub tsev, thiab xws li piv txwv ntau ntau. Tsab ntawv tsa suab sensor los yog tsab ntawv tsa suab yog siv nyob rau hauv lub tsev thiab muaj tswb tshuab, lawv muaj nyob rau hauv lub schemes robotics thiab automation, xab lub cev muaj zog ceev, thiab lwm yam Tab sis nyob rau hauv tas li ntawd mus muaj daim ntaub ntawv, tsab ntawv tsa suab sensor, nws tseem tau mus nrhiav daim ntawv thov nyob rau hauv lub tsev. Tshwj xeeb tshaj yog yog hais tias koj ua ib tug tsab ntawv tsa suab sensor nrog koj ob txhais tes, ces paub nws tswvyim ntawm kev ua hauj lwm, koj yuav siv tau qhov no ntaus ntawv mus rau tig los yog tua tej khoom siv.

Cia saib lub ntsiab yog ib feem ntawm cov khoom. Tus thawj yam uas koj yuav tau pib ua kom tau ib tsab ntawv tsa suab sensor nrog koj ob txhais tes, nws yog los xyuas kom meej lawv tej zaub mov. Lub hwj chim mov yuav tsum thawj thiab foremost nyab xeeb, muaj ib tug ua tau me me luaj li cas thiab yuav nyob rau lub lag luam nruam nyob rau hauv load. Zoo suited rau lub hom phiaj no, tus qauv fais fab mov them lub roj teeb los yog lwm yam nrog ib tug tso zis voltage ntawm tsib volts. Ua ib tug tsab ntawv tsa suab sensor nrog koj ob txhais tes tsuas, nws tsis yuav tsum tau scarce los yog kim yam khoom.

Tam sim no xaiv ib tug photocell, rau peb cov hom phiaj, koj muaj peev xwm siv tau cov, nws cheeb tsam muaj tsis muaj ntsiab lus, ib tug me ntsis rau yav tom ntej, peb yuav nrhiav tau tawm yog vim li cas. Lub cathode ntawm ib tug photocell txuas mus rau qhov zoo fais fab mov davhlau ya nyob twg. Tam sim no tam sim no tsis pub tshaj ntes, nws yuav tsum ntws los ntawm qhov tam sim no kev ntsuam xyuas, txwv tsis pub nws yuav hlawv. Raws li Ohm txoj cai, peb xam lub nominal tsis kam, thiab solder nws mus rau lub anode davhlau ya nyob twg ntawm lub photocell.

Tam sim no Trimpot sufficiently 10k, ib tug ntawm cov terminals soldered mus rau Rho tawm fais fab mov, lub thib ob - nyob rau free kawg ntawm qhov tam sim no txawj ua hauj. Tam sim no sau lub tswvyim emmiternogo follower siv ib tug transistor nrog npn hlws ris. Base nws yog muab sib khi rau cov dawb kawg ntawm lub trimming resistor. Lub collector yog ncaj qha mus soldered mus rau qhov zoo davhlau ya nyob twg ntawm lub hwj chim qhov twg los, thiab lub emitter Circuit Court muaj xws li ib tug me me relay lub hwj chim, nyob voltage ntawm tsib volts. Qhov thib ob kawg ntawm tus relay kauj, peb soldered mus rau qhov tsis zoo davhlau ya nyob twg los qhov twg los. Lub relay hu sau lub tswvyim self-ceev, uas yog, nyob rau thawj cov lus tsa suab sensor yog txhais, hauv lub relay yuav nruj thiab koj cov neeg yuav muab lawv tus kheej noj. Dawb relay hu mus rau lub load, xws li teeb pom kev zoo los yog ib daim kab xev recorder, nws tag nrho cov nyob rau koj lub tswv yim. Raws li koj tau pom, ua ib tug tsab ntawv tsa suab sensor nrog koj txhais tes yog ib qho yooj yim. Qhov loj tshaj plaws nyob rau hauv cov ntaub ntawv no - tsis txhob tshooj rau cov neeg vim hais tias cov relay siv nyob rau hauv lub Circuit Court, tsis tshua muaj hwj chim. Tab sis raws li cov load, peb yuav siv lwm relay, muaj ntau haib hu, uas yuav muab rau koj cov load, yuav ua li cas koj xav tau.

Mus pib dua lub ntaus ntawv mus rau nws cov thawj lub xeev sufficiently luv luv interrupt lub hwj chim. Muaj xws li nyob rau hauv lub khoom noj khoom haus saw yog ib tug me me hloov nrog momentary. Lub tawg qhov chaw tej zaum yuav ib tug laser pointer, muab nws nrog ib tug mus tas qhov chaw ntawm peb cov zaub mov. Tam sim no kuv to taub yog vim li cas lub photocell cheeb tsam tsis ua si tej lub luag hauj lwm, monochrome teeb pointer thiab lub teeb beam tsis hloov nyob rau hauv loj.
