YUAV UA LI CAS YUAV TSUM TAU NYEEM NQI LIGHT SWITCH nrog MOSFET

Nyob zoo, cov phooj ywg hauv txoj haujlwm no kuv yuav qhia daim duab qhia yooj yim ntawm yuav ua li cas thiaj ua hmo tsis siv neeg

qhib kev hloov siv ib mosfet thiab qee qhov khoom me me uas kuv tau tswj kom khaws los ntawm a

teeb hmo ntuj tiag. Ok, yog li tsis muaj sijhawm ntxiv lawm cia pib.

Cheebtsam yuav tsum tau pib thaum tsaus ntuj teeb:

Mosfet IRFZ44N

LDR (LIGHT DEPENDENT RESISTOR)

RESISTOR 4.5Mohm

thauj khoom (qhov no 12v coj sawb)

Lub hwj chim (hauv qhov no 9v roj teeb)

Kauj Ruam 1: Tsis Siv Neeg Hmo Hmo Teeb Pom Kev

Lub teeb tsaus ntuj yog lub teeb pom kev me me, feem ntau yog hluav taws xob, tso rau kom yooj yim lossis yooj yim hauv thaj chaw tsaus ntuj lossis thaj chaw uas yuav tsaus ntuj rau qee lub sijhawm, xws li thaum tsaus ntuj lossis thaum muaj xwm txheej ceev. Cov tswm ciab kub me me uas ua haujlwm zoo ib yam raug xa mus rau "tealights".

Hauv txoj haujlwm no, peb yuav ua kom lub tsev qhib hmo ntuj qhib kev siv mosfet qhov haujlwm no yuav ua haujlwm zoo dua

yog tias koj yuav muaj qhov LDR tseeb hauv daim vis dis aus kuv qhia tias qhov no zoo sib xws tab sis tsis zoo ib yam koj xav tau tus nqi tiv thaiv loj

zoo li ib qho hauv qib 3 kuv xav tias yog 4.5M tab sis tsis paub tseeb qhov haujlwm no txhais tau tias khaws cov khoom yooj yim thiab pub dawb yog tias ua tau

yog li peb yuav siv ntau ntu raws li peb tuaj yeem ua los ntawm peb qhov chaw CHEAP NIGHTLIGHT.

Kauj Ruam 2: Mosfet Transistor Projects

Nov yog tus tiv thaiv uas kuv tau tham txog yog tias koj yuav siv ldr koj yuav tsis xav tau tus tiv thaiv no

tsuas yog 100K yuav txaus thiab tam sim no cia saib lub me me xiav LED. Nws puas muaj leej twg qhov no yog dab tsi?

Zoo li tus coj tau txais tus pin zoo li LED +thiab - tab sis yog LDR?

Yog ua yeeb yam zoo li ib tus tab sis tseem tsis paub tseeb. Yog leej twg paub tso rau hauv cov lus hauv qab no.

Tam sim no peb muaj tag nrho peb cov khoom tso cai ua qhov tsis siv neeg hmo ntuj teeb pom kev zoo Circuit….

Rau nostalgist tawm muaj thawj daim duab yuav zoo li hauv lub tsev kawm ntawv qub ntawm hluav taws xob

Kauj Ruam 3: Tsis Siv Neeg Hmo Hmo Teeb Pom Kev Zoo

Ntse teeb pom kev zoo yog lub teeb pom kev zoo thev naus laus zis tsim los rau kev siv hluav taws xob qhov no tuaj yeem suav nrog cov cuab yeej ua haujlwm tau zoo thiab kev tswj lub tshuab uas hloov kho raws qhov xwm txheej xws li muaj neeg nyob lossis nyob nruab hnub. Teeb pom kev yog lub hom phiaj thov siv lub teeb kom ua tiav qee qhov zoo nkauj lossis siv tau. Nws suav nrog teeb pom kev ua haujlwm, teeb pom kev zoo, thiab teeb pom kev dav.

Suab zoo tsis muaj peev xwm ua kom lub teeb pom kev zoo pheej yig thiab muaj txiaj ntsig uas tuaj yeem siv qhov xwm txheej tsis zoo yog tias koj xaiv li ntawd lossis niaj hnub ua haujlwm rau koj lub vaj, tsev lossis txhua yam uas koj xaiv.

Daim duab ntawm qhov tsaus hloov yog qhov yooj yim heev rau rov ua dua thiab kuv vam tias koj yuav siv qhov no thiab txhim kho nws.

Kauj Ruam 4: Kev Hloov Ua Tsaus Ntuj Yuav luag nyob ze

Tus photoresistor (lossis lub teeb nyob ntawm tus tiv thaiv, LDR, lossis xov tooj ntawm tes ua duab) yog lub teeb tswj tau qhov sib txawv resistor. Kev tiv thaiv ntawm photoresistor txo qis nrog qhov teeb meem teeb pom kev zoo ntxiv; Hauv lwm lo lus, nws nthuav tawm photoconductivity. A photoresistor tuaj yeem siv rau hauv lub teeb pom kev pom lub teeb pom kev zoo thiab lub teeb qhib thiab qhib-tsaus-ua haujlwm hloov pauv.

Photoresistors yog cov cuab yeej siv hluav taws xob tsawg dua li photodiodes lossis phototransistors: ob qho khoom siv tom kawg yog cov cuab yeej siv hluav taws xob muaj tseeb, thaum lub tshuab photoresistor yog ib qho tsis tiv thaiv thiab tsis muaj PN-hlws ris. ua rau lawv tsis tsim nyog rau daim ntawv thov xav tau kev ntsuas meej lossis rhiab rau lub teeb photons.

Photoresistors tseem tuaj yeem pom qee qhov kev ncua ntawm kev raug rau lub teeb thiab tom qab txo qis hauv kev tiv thaiv, feem ntau nyob ib puag ncig 10 milliseconds. Lub sijhawm lag luam thaum mus los ntawm qhov tsaus ntuj mus rau ib puag ncig tsaus ntuj yog qhov ntau dua, feem ntau ntev li ib pliag. Cov cuab yeej no ua rau lawv tsis tsim nyog rau lub teeb pom kev nrawm nrawm tab sis qee zaum siv los ua kom cov lus teb ntawm lub teeb liab suab nrawm.

Kauj Ruam 5: Lub Teeb Nyob Ruaj Ntseg

Ib lub teeb-tiv taus tus tiv thaiv hu ua LDR, photoresistor, photoconductor, lossis photocell yog qhov sib txawv resistor uas nws tus nqi txo nrog nce qhov teeb meem teeb pom kev zoo.

LDR yog ua los ntawm cov khoom siv hluav taws xob tiv taus siab. Yog tias lub teeb ntog ntawm lub cuab yeej muaj qhov txaus txaus, photons nqus los ntawm cov khoom siv hluav taws xob muab cov hluav taws xob txaus ua kom lub zog dhia mus rau hauv pawg ua haujlwm. Qhov ua tau hluav taws xob pub dawb (thiab nws tus khub qhov) ua hluav taws xob, yog li txo qis kev ua haujlwm.

Cov cuab yeej siv hluav taws xob tuaj yeem yog sab hauv lossis sab nraud. Hauv cov cuab yeej siv sab hauv, tsuas yog muaj cov khoom siv hluav taws xob nyob hauv pawg valence, thiab yog li cov photon yuav tsum muaj lub zog txaus kom ua rau lub tshuab hluav taws xob zoo thoob plaws txhua qhov bandgap. Cov cuab yeej txuas ntxiv muaj cov khoom tsis huv ntxiv, uas muaj lub zog hauv av hauv lub xeev kom ze rau cov pab pawg ua haujlwm - txij li cov tshuab hluav taws xob tsis muaj kom dhia mus deb, qis zog photons (piv txwv li ntev nthwv dej thiab qis dua) yog txaus los ua rau lub cuab yeej.

Yog li tom qab qee qhov kev tshawb fawb, peb pom peb qhov paub tsis meej peb tsis muaj LDR tab sis peb muaj cov duab hluav taws xob tiv thaiv dab nyob hauv qhov tsaus ntuj muaj qhov ua haujlwm loj yog li 4.5M tuaj yeem yog qhov muaj txiaj ntsig YUAV UA LI CAS ???

Kauj Ruam 6: TSHAWB TSHUAJ TAWM OFF Circuit Diagram

Tsis siv neeg hmo ntuj hloov hluav taws xob hloov pauv nrog ib lub mosfet thiab photoresistor thiab 4.5M tus tiv thaiv qhov no yog txhua yam peb siv hauv cov vis dis aus thiab yog tias koj nyiam nws thiab pom nws qhia paub nyob twj ywm.

Tam sim no tsuas yog siv koj lub tswv yim thiab ua lub thawv/lub thawv rau muab tag nrho cov xov hlau thiab lub mosfet transistor koj tuaj yeem siv cov yas yas qub uas koj tsis siv ntxiv lawm hauv cov vis dis aus kuv tau siv lub qub pheej yig fais fab lub txhab nyiaj tab sis koj tuaj yeem siv tau tic-tac rooj plaub qub tes pleev (Nivea) thiab ntau yam ntxiv. Ua tsaug rau txhua tus nyeem thiab pom koj ntawm cov channel
