Koj puas tau muaj teeb meem thaum nres tsheb rau lub tsheb xws li tsheb, tsheb thauj khoom, tsheb kauj vab lossis lwm yam, tom qab ntawv qhia kuv yuav qhia koj yuav ua li cas kov yeej qhov teeb meem no siv lub tsheb yooj yim lub tswb nres tsheb siv PIR Sensor. Hauv cov kab ke no thaum nres koj lub tsheb lossis nqa/tsav nws rov qab, cov kab ke no yuav ceeb toom koj yog tias koj ua qee yam tsis raug uas yuav ua rau puas tsuaj thaum nres tsheb. Qhov no yuav tiv thaiv kev puas tsuaj rau lub tsheb nrog rau tus kheej lub neej thiab khoom siv.

Zuag qhia tag nrho Circuit yog yooj yim heev hauv txoj hauv kev uas txawm tias tus pib tuaj yeem tsim nws tus kheej hauv txoj hauv kev yooj yim super nrog tsuas yog ob peb yam khoom thiab khoom siv. Nrog kev pab los ntawm arduino peb tseem tuaj yeem ua qhov txheej txheem no kom raug kom peb tuaj yeem siv tau ntau yam kev thov sib txawv xws li kev ruaj ntseg hauv tsev, tiv thaiv tub sab nyiag thiab lwm yam. yog li cia pib.

Kauj ruam 1: Cov khoom xyaw koj xav tau

1. PIR sensor yog
2. NPE Transistor
3. Diodes
4. 7805 tus tswj hwm IC
5. Zero PCB/Perf Board
6. Buzzer
7. Txuas xov hlau
8. USB hlau
9. Fais fab mov

Kuj Cov Cuab Yeej koj yuav xav tau:

* Soldering Hlau

* Dremel cov cuab yeej

* Phom phom

* Multimeter

* Hlau stripper

Kauj Ruam 2: Nkag Siab Lub Hauv Paus Ntsiab Cai

Lub PIR sensor yog ib qho uas paub txog kev txav chaw hauv qhov txwv, feem ntau nyob ib puag ncig 7 ko taw. Lawv yog cov me me, pheej yig, lub zog qis, siv tau yooj yim. Lawv feem ntau hu ua PIR, "Passive Infrared", "Pyroelectric", lossis "IR motion" sensors. Lub sensor "hnov qhov txav" los ntawm kev txheeb xyuas thaj ua rau thaj ntawm cov duab hluav taws xob tawg nyob rau hauv pem hauv ntej ntawm nws. Txhua yam tso tawm qee qib ntawm cov duab hluav taws xob infrared (IR hluav taws xob), thiab ntau lub teeb hluav taws xob infrared los ntawm cov khoom tawm, ntau lub ntsuas hluav taws xob tuaj yeem "taug qab" nws thiab tsim lub teeb liab uas tuaj yeem siv los ua rau lwm qhov txiaj ntsig. Yog tias koj yuav saib mus rau hauv koj li PIR module koj yuav pom tias qhov ntsuas qhov ntsuas muaj ob lub zog me me ntawm nws. Cov potentiometers hloov kho qhov rhiab ntawm lub sensor thiab ncua sijhawm ntawm cov cim ua tiav. Tam sim no peb muaj kev paub yooj yim ntawm lub ntsuas cua zoo li no, yog li tam sim no cia peb tsim lub Circuit Court siv cov khoom siv tau hais los saum no.

Kauj Ruam 3: Daim Duab Circuit thiab Ua Haujlwm

Nov yog daim duab qhia chaw. Diodes tau siv los ua tus choj txuas uas yuav hloov AC rau DC yog tias koj siv AC mov thiab yog tias koj siv ncaj qha DC cov khoom siv nws yuav hla nws lossis koj tseem tuaj yeem txuas DC muab khoom tom qab kev hloov kho hluav taws xob. Cov khoom siv DC no yog pub rau 7905 tus tswj hwm IC kom zoo tshaj 5v tso zis. Tam sim no qhov 5v tso tawm tau pub rau hauv lub suab ntawm transistor thiab pub rau hauv PIR + davhlau ya nyob twg. Txuas txhua qhov tsis zoo ntawm PIR sensor thiab 7085 IC nrog lub siab tsis zoo ntawm rectifier.

Tam sim no thaum twg los xij muaj teeb meem tshwm sim nyob rau hauv pem hauv ntej ntawm lub sensor, nws yuav tig rau lub hauv paus pib ntawm transistor li no yuav ua tiav Circuit Court ntawm Buzzer thiab nws yuav nrov li lub tswb. Hauv txoj hauv kev no yooj yim ua haujlwm thiab tam sim no cia ua ib feem soldering.

Kauj Ruam 4: Tsim Vaj Tsev

Tam sim no nws yog lub sijhawm los txhawm rau txhua yam khoom kom raug. Solder lub Circuit Court raws li daim duab qhia chaw. Xaiv qhov ntsuas kub kom haum rau cov hlau txuas yog tias koj muaj qhov ntsuas kub sib txawv. Siv cov cua sov ua kom sov ua kom txhua qhov kev sib txuas nyab xeeb xws li yuav tsum tsis txhob muaj qhov luv. Siv tes pab yog xav tau. Koj tseem tuaj yeem siv Etching PCB txheej txheem yog tias koj yog tus tswv hauv nws.

Kauj Ruam 5: Npaj Vaj Tsev

Kuv tau nqa ib lub voos xwmfab ntawm lub thawv uas ua los ntawm cov duab los qhia. Ntsuas qhov ntev ntawm PIR thiab cim kom txiav qhov tsim nyog thiab kho sab hauv. Siv cov kua nplaum kub los yog lwm yam nplaum los tso rau hauv qhov chaw. Ua tib zoo saib xyuas thaum siv cov nplaum xws li nws yuav tsum tsis txhob npog qhov PIR sensor, txwv tsis pub nws yuav tsis pom qhov txav/ teeb meem sab nraum peb lub tsheb.

Kauj Ruam 6: Txhim Kho Circuit Court Rau Hauv Vaj Tsev thiab Tsheb

Kho lub PIR sensor mus rau hauv lub tsheb zoo li txoj kev uas nws npog qhov siab tshaj plaws sab nraum lub tsheb thiab kho ob lub hwj chim kom nce lossis txo qhov rhiab heev thiab ncua sijhawm. Tam sim no koj tuaj yeem txuas 5 txog 12volts rau hauv USB chaw nres nkoj. 7805 IC yuav ua rau nws 5 volts uas yuav pub rau txhua qhov ntawm Circuit Court. Kuv tau siv 9 volts roj teeb txhab nyiaj hauv kuv rooj plaub.

Rau lub zog hluav taws xob koj tseem tuaj yeem siv suab paj nruag system USB chaw nres nkoj thiab them chaw nres nkoj uas tseem yuav muab koj 5 volt mov rau kev ua haujlwm.

Kauj Ruam 7: Kawg thiab Xeem

Tam sim no nws lub sijhawm sim. Raws li koj tuaj yeem pom thaum twg los xij muaj teeb meem, txawm tias tib neeg tab tom los ntawm nws, nws yuav ua rau koj paub nws los ntawm lub suab ceeb toom los ntawm lub suab nrov. Sai li koj hnov lub suab nrov nrov uas txhais tau tias muaj qhov thaiv ib puag ncig nws uas tuaj yeem ua rau koj lub tsheb puas. Hurray! Koj tau cawm koj lub tsheb los ntawm kev puas tsuaj.

Qhov ntawd yog nws! Kuv vam tias koj txaus siab rau txoj haujlwm thiab pom nws muaj txiaj ntsig.

Thov pov npav yog tias koj nyiam qhov haujlwm

Tawm tswv yim hauv qab no yog tias koj muaj lus nug

Ua tsaug rau kev nyeem ntawv thiab zoo li ib txwm…
