Hav guys!

Hauv txoj haujlwm no, peb yuav pom daim ntawv thov Kev Ruaj Ntseg Hauv Tsev yooj yim hu ua Electronic Eye Controlled Security System siv LDR ua lub cim tseem ceeb thiab ob peb yam ntxiv.

Qhov muag hluav taws xob kuj tseem hu ua khawv koob qhov muag. Raws li kev siv lub tshuab ua haujlwm yog thev naus laus zis niaj hnub no, tsuas yog xav txog lub tswb qhov rooj uas tuaj yeem nrov thaum tus neeg mus ntsib koj lub tsev. Qhov no tseem muab kev nyab xeeb thaum ib tus neeg tab tom sim nkag mus rau hauv koj lub tsev yam tsis tau kev tso cai los ntawm koj. Qhov muag hluav taws xob yog cov cuab yeej siv hluav taws xob yooj yim uas saib tas li yog tias leej twg tuaj xyuas koj lub tsev.

Kauj Ruam 1: Yuav Tsum Kho Vajtse

Cov hauv qab no tau siv:

· 7805 Tus tswj hwm

· Resistors - 220Ω x 2, 1KΩ x 2, 100KΩ

· 1N4007 PN Diode

· Capacitors - 1µF, 10µF

· Transistors - BC 547 x 2

· Lub Teeb Ntsuas Tus Kheej (LDR)

· Lub suab nrov

· LED ua

· Txuas cov xov hlau

· Roj teeb 9V

Kauj Ruam 2: Circuit Schematic & Ua Haujlwm

Lub voj voog no tuaj yeem faib ua ob ntu. Ib qho yog lub zog hluav taws xob thiab lwm qhov yog lub logic Circuit. Hauv qhov hluav taws xob muab hluav taws xob, 9V muab los ntawm lub roj teeb tau hloov pauv mus rau 5V. Qhov logic Circuit ua haujlwm lub suab nrov thiab LED thaum muaj duab ntxoov ntxoo poob ntawm LDR.

Cov khoom siv hluav taws xob suav nrog roj teeb, diode, tus tswj hwm thiab lub peev xwm. Thaum pib lub roj teeb 9V txuas nrog lub diode. Diode siv ntawm no yog qhov yooj yim PN kev sib txuas diode ntawm 1N4007 series. Hauv qhov kev sib tham no, 1N4007 tau txuas nrog rau yav tom ntej kev mob siab rau.

Lub hom phiaj tseem ceeb ntawm cov diode hauv Circuit no yog txhawm rau tiv thaiv lub Circuit Court los ntawm kev thim rov qab piv txwv li txhawm rau tiv thaiv Circuit Court yog tias muaj lub sijhawm twg los lub roj teeb tau txuas nrog nyob rau hauv rov qab polarities. Yog li, P-N kev sib tshuam diode txuas nrog rau hauv kev tsis ncaj ncees yav tom ntej tso cai rau tam sim no ntws tsuas yog hauv ib qho kev qhia thiab yog li kev tiv thaiv Circuit Court tuaj yeem tiv thaiv. Muaj qee qhov kev poob qis hla lub diode. Qhov hluav taws xob ntawm 0.7V tau poob thoob plaws lub diode.

Tus tswj hwm yog siv rau kev tswj hwm qhov hluav taws xob tso tawm ntawm Circuit Court. Tus tswj hwm IC siv ntawm no yog 7805. 78 sawv cev rau koob thiab 05 sawv cev rau qhov hluav taws xob tso tawm. Yog li qhov hluav taws xob ntawm 5V tau tsim tawm los ntawm tus tswj hwm. Ob lub capacitors tau siv ua ntej thiab tom qab tus tswj hwm. Ob lub tshuab hluav taws xob no tshem tawm cov ripples. Yog li qhov hluav taws xob tas li tau tsim los ntawm qhov tso tawm ntawm tus tswj hwm, uas tau siv rau lub logic Circuit.

Kauj Ruam 3: PCB Tsim

Daim duab saum toj no qhia txog PCB tsim siv Eagle software.

Parameter txiav txim siab rau PCB tsim

1. Kab dav tuab yog yam tsawg 8 mil.

2. Qhov sib txawv nruab nrab ntawm lub dav hlau tooj liab thiab tooj liab yog yam tsawg 8 mil.

3. Qhov sib txawv nruab nrab ntawm kab mus rau kab yog yam tsawg 8 mil.

4. Qhov me me qhov loj me yog 0.4 hli

5. Txhua txoj kab uas muaj txoj hauv kev tam sim no xav tau cov kab tuab.

Kauj Ruam 4: Xa Gerber rau Chaw Tsim Khoom

Koj tuaj yeem kos PCB Schematic nrog ib qho software raws li koj qhov yooj yim. Nov kuv muaj kuv tus kheej tsim thiab Gerber cov ntawv txuas nrog. Tom qab koj tsim cov ntaub ntawv Gerber koj tuaj yeem xa nws mus rau koj lub chaw tsim khoom.

Kuv yog LIONCIRCUITS. Lawv muab cov laug cam zoo hauv tus nqi zoo tshaj. Tsis tas li, lawv muaj kev thauj khoom dawb thoob plaws Is Nrias teb.

Kauj Ruam 5: Tos rau Fabricated Board los ntawm LIONCIRCUITS

Kuv yuav sau ntu-2 cov lus qhia nyob rau lub asthiv tom ntej tom qab kuv tau txais daim ntawv tsim daim ntawv LIONCIRCUITS.

Txog thaum ntawd nyob twj ywm.
