Panic Alarm Button Circuit Siv 555 Timer IC (Ntu-1)

Panic Alarm Circuit tau siv los xa lub teeb liab xwm txheej tam sim rau cov neeg nyob hauv ib qho chaw nyob ze kom hu rau kev pab lossis ceeb toom rau lawv. Qhov xwm txheej txaus ntshai tuaj yeem yog ib qho, nws tsis txwv rau qee qhov xwm txheej. Ib tus tuaj yeem tuaj yeem khaws lub laub khawm ntawm tes kom ncav cuag qhov deb lossis qhov chaw xis nws ua kom nrawm nrawm hauv qhov ntsiag to los ntawm nias ib lub pob. Qhov taw qhia ntawm xwm txheej ceev tuaj yeem yog nyob rau hauv daim ntawv ntawm pom lossis hnov lub teeb liab, uas tuaj yeem kho tau ntawm ob peb metres deb los ntawm xaim.

Kauj Ruam 1: Yuav Tsum Kho Vajtse

Cov hauv qab no tau siv:

1. 555 Timer IC - 1

2. Transistor BC547 - 1

3. Buzzer (6-12V)-1

4. LED - 1

5. Tactile hloov - 2

Kev xaiv teeb tsa:

Muaj peb qhov kev teeb tsa nrov ntawm 555 timer IC, 1. Astable multivibrator

2. Monostable multivibrator

3. Bistable multivibrator

Lawv txawv los ntawm tus naj npawb ntawm cov xeev ruaj khov hauv Circuit Court. Hauv peb qhov xwm txheej, peb xav tau ob lub xeev ruaj khov. Ib lub xeev tau ceeb toom ON thiab lwm lub xeev ceeb toom OFF. Yog li ntawm no peb tau teeb tsa 555 hauv Bistable hom. Thaum nias lub pob, lub teeb liab yuav tsum raug xa mus rau qhov chaw nyob hauv daim ntawv hnov thiab pom. Txhawm rau tua lub tswb peb siv lwm lub pob nyob ntawm peb qhov chaw lossis ntawm qhov chaw qhia. Nov yog Kev Tsov Rog Yooj Yim Yooj Yim nrog kev ua haujlwm qis tam sim no tau ua tiav.

Parameter txiav txim siab rau PCB tsim

1. Kab dav tuab yog yam tsawg 8 mil.

2. Qhov sib txawv ntawm lub dav hlau tooj liab thiab tooj liab yog qhov tsawg kawg yog 8 lab.

3. Qhov sib txawv nruab nrab ntawm txoj kab rau kab laum yog yam tsawg kawg ntawm 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.

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 rau kev tsim.

Kuv tau muab nws tso rau LIONCIRCUITS. Lawv nyob hauv Is Nrias teb. Kuv xav kom koj xaj los ntawm lawv. Lawv muab Tus nqi qis tus qauv thiab lawv cov UI yog qhov zoo tiag tiag thiab siv tau yooj yim. Tsuas yog tso xaj online thiab tau txais koj daim ntawv pov thawj hauv 6 hnub xwb.

Kuv yuav sau ntu-2 ntawm qhov tsis txaus ntseeg nyob rau lub lim tiam tom ntej tom qab kuv tau txais cov ntawv tsim.
