Ua kom yooj yim Motion Sensor Teeb! (PIR): 13 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Ua kom Me Me & Yooj Yim Pom Kev Pom Kev Pom Lub Teeb nrog Tsawg Nyiam thiab Tsawg Cheeb Tsam.

Ib Tus Pib Tseem tuaj yeem Ua Qhov No.

Kev nkag siab yooj yim ntawm yuav ua li cas transistor ua haujlwm thiab kev paub ntawm Anode thiab Cathode tsuas yog xav tau thiaj li Ua rau Nws Tension Dawb!

Kauj Ruam 1: Sau Cov Khoom

Ib tus tuaj yeem Yuav Txhua Yam Siv Hauv Txoj Haujlwm no los ntawm Ebay.

Thaum Kuv Tau Txais Feem Ntau Yam Ntawm Kuv Lub Hauv Paus Hauv Zos & Robotics Khw yog li kuv tsis yuav los ntawm ebay.

Txawm li cas los xij, Ntawm no yog Daim Ntawv Teev Npe ntawm Yam Uas Xav Tau:

1) PIR Tsab ntawv tsa suab Sensor. (Qhov tseem ceeb, kuv siv HC-SR501)

Nco tseg tias txhua tus PIR Chaw Tsim Tshuaj yuav muaj qhov sib txawv Pinout. Yog li Thov paub meej tias Pinout ntawm PIR ua ntej ua qhov haujlwm no. [Kuv PIR Tau Pinout - VCC | Tso zis | Hauv av || (Los ntawm Rov Qab Sab laug mus Rau Txoj Cai)]

2) BC547 NPN Transistor

3) (4 Pcs.) Dawb 5mm Leds

4) Rooj Tswjhwm Tooj Liab Me

5) 2 Pin Ntsia Hlau Terminal

6) 3 Pin Txoj Cai Lub Taub Hau

Kauj ruam 2: Circuit Court

Ib qho yooj yim Circuit Court, Tswj los ntawm ob yam tseem ceeb.

1) BC547 Transistor

2) PIR Tsab ntawv tsa suab Sensor

Qhov no tuaj yeem ua tiav ntawm Perfboard ib yam.

Piav qhia:

Thaum PIR Sensor paub txog tib neeg cuam tshuam lossis lub teeb khiav @ 38KHz

tom qab ntawd nws yog Pin Output Ua los ntawm LOW mus rau HIGH uas ua rau 3.3v Cov Khoom Siv Hauv Pin Pin, Yog li Peb Yuav Siv Tus pin tso zis los hloov lub transistor rau thiab tawm uas yuav ua rau On thiab tawm ntawm leds ib yam.

Cov Leds tau txuas rau hauv Series Yog li ntawd lawv yuav haus tag nrho 12v Cov khoom siv ib zaug hloov pauv thiab uas yuav tsis ua rau hlawv.

Nco tseg: Tsuas yog muab 12v, Yog Voltage Ntau dua li qhov no nws yuav ua rau hlawv cov leds.

thiab PIR muaj tus tswj kev tsim kho uas yuav lees txais 12v.

Kauj Ruam 3: Breadboard Circuit

Rau Cov Neeg uas xav tsim nws ntawm Breadboard.

Kauj Ruam 4: Eagle PCB Cov Ntaub Ntawv

Tsuas yog Luam Pdf nrog.

thiab kuv yuav siv Toner Transfer Method.

nws yuav yog koj txoj kev xaiv uas koj yuav xaiv vim qhov kawg yuav zoo ib yam.

Kauj ruam 5: Hloov daim Artwork

Tsuas yog Nyuaj Nyuaj nrog hlau nrog puv Kub Dial rau 4-5 feeb.

Tom qab qhov tam sim ntawd poob rau hauv Dej thiab maj mam Rub daim ntawv ntawm pcb nrog koj tus ntiv tes xoo.

Artwork yuav tsum tau txuas nrog Pcb.

Txwv tsis pub yog hais tias cov kab tawg lawm ces sim dua.

Kauj ruam 6: Etch Nws

Tam sim no muab PCB rau hauv Ferric Chloride.

Koj tuaj yeem siv HCL+ Hydrogen Perxide ib yam nkaus.

Kauj Ruam 7: Laum Qhov

Kuv siv Kuv Li Laum Tes los laum qhov.

nws tsuas yog siv tsis tau laum yuav los ntawm ebay rau 2 $, Tau txais nws lub caij nplooj ntoo hlav xoob tom qab ua 15 pcb's

Yog li, Kuv tab tom hloov mus rau lub tshuab laum rau kuv cov phiaj xwm yav tom ntej.;)

Kauj Ruam 8: Solder Screw Terminal

Nco ntsoov laum nrog 1mm ntsis rau qhov no vim tias lawv muaj hom dav dav.

Kauj Ruam 9: Kab laug sab xis Lub Taub Hau Taub Hau

Kauj Ruam 10: Coj Leds

Kuv siv dawb vim 3v x 4 leds = 12v

uas yuav tsis hlawv cov leds.

thiab xyuas kom tseeb tias Anode thiab Cathodes ntawm leds.

Kauj Ruam 11: Solder Transistor

Nco ntsoov ntsib lub tiaj tiaj ntawm transistor ntawm leds.

Kauj Ruam 12: Solder PIR

Txog tam sim no koj yuav tau paub tias vim li cas kuv thiaj li muab lub taub hau kaum sab xis.

nws tau muab tso rau qhov chaw nws tsab ntawv tsa suab hnov ib feem ntawm peb tus kheej.

Kauj ruam 13: Hwj chim nws

Tam sim no siv nws nrog 12v.

Muab lub ntsuas sov kom sov li ntawm 10-60 Sec.

Thiab sim nws.
