Qhov no puas tau tshwm sim rau koj?

Koj rov qab los ntawm hnub noj hmo zoo nkauj thiab thaum koj qhib lub qhov rooj kaw ntawm koj lub nkas -las koj paub tias koj tawm ntawm lub nkas -las lub teeb ON. Koj tau siv ob peb teev nyob sab nraud nrog koj tus khub ua rau nws zoo siab thiab txhua lub sijhawm lub teeb no tau qhib. Koj tam sim tig mus thiab saib nws lub ntsej muag kom pom kev npau taws ntsiag to ntawm nws lub ntsej muag. Zoo, txaus ntawm qhov uas. Yog li, hauv qhov kev qhia no, Kuv yuav qhib thiab tua lub tsheb teeb siv lub PIR sensor. Thaum lub ntsuas pom pom cov khoom txav, nws tig rau lub teeb thiab thaum cov khoom txav mus, nws tig nws tawm. Thaum kawg, Kuv yuav ua kom ntseeg tau tias lub teeb tsuas yog qhib thaum hmo ntuj (thaum nws tsaus ntuj).

Kauj ruam 1: Logic

Hauv txoj haujlwm no, Kuv yuav siv lub PIR sensor nrog rau LDR kom qhib lossis tua lub teeb uas siv Relay.

Yam uas kuv xav tau los txiav txim ua ntej tsim lub Circuit Court yog:

- Lub teeb yuav tsum qhib tsuas yog thaum chav tsaus ntuj thiab thaum pom lub suab txav.

- Lub teeb yuav tsum tua tom qab 30 vib nas this ntawm cov khoom tawm hauv lub sensor nyob sib ze.

- Qhov tseem ceeb tshaj plaws, peb yuav tsum tso lub LDR tso rau qhov chaw uas nws tsis tua lub teeb kom sai li sai tau thaum nws taws.

Kauj ruam 2: Kho vajtse

Rau qhov kev qhia no peb xav tau:

Lub Hom Phiaj Tseem Ceeb PCB

2 x HC-SR501 PIR Sensor

2 x 1N4148 Cov Teeb Meem Me Me Hloov Hloov Diodes

1 x 1N4007 Cov Hluav Taws Xob Hluav Taws Xob, Cov Hluav Taws Xob Hluav Taws Xob Tam Sim No los tiv thaiv micro-maub los ntawm qhov ntsuas hluav taws xob nce

1 x LDR

1 x 10K Trimmer Potentiometer

2 x 470 Ohms Resistor

1 x 10K Resistor

1 x 1K Resistor

1 x 2N3906 Lub Hom Phiaj PNP Transistor

1 x 2N2222 Lub Hom Phiaj NPN Transistor

1 x 5V Relay

1 x LED los tso saib cov xwm txheej

5 x Terminal Thaiv

1 x 220V txog 5V Buck Step Down Module

Ob peb Txuas Cov Cables Thiab Cov Khoom Siv Hluav Taws Xob

Kauj ruam 3: Sib dhos

Thawj zaug txuas LDR thiab teeb lub teeb pom kev me ntsis.

Raws li peb txhua tus paub peb yuav tsum teeb tsa qhov faib hluav taws xob kom siv LDR hauv Circuit, yog li, kuv tab tom ntxiv qhov 10K POT thiab 470ohms resistor los teeb tsa qhov faib hluav taws xob me ntsis. Los ntawm kev kho qhov kev tiv thaiv ntawm POT peb tuaj yeem kho qhov kev siv zog ntawm lub hnub ci uas lub voj voog no yuav ua haujlwm.

Tam sim no, cia nruab PIR sensor. Txuas VCC mus rau +5v thiab GND rau hauv av. Tom qab ntawd txuas 1N4148 diode rau OUT ntawm lub sensor. Hauv Circuit no, kuv tab tom txhim kho tsuas yog ib qho sensor txawm li cas los xij hauv qhov haujlwm tiag kuv tau siv 2 lub ntsuas kom ntes me ntsis ntau dua 180 degrees. Yog li, txhawm rau zam kev ntsuas ntawm rov qab pub mis rau ib leeg peb yuav tsum teeb tsa lub diode rau OUT tus pin ntawm txhua lub sensor. Yog tias koj xav ntes cov lus tsa suab ntawm 360 degrees koj yuav xav tau 3 txog 4 tus cim thiab diode khub kom ua tiav qhov ntawd.

Tam sim no peb muaj PIR sensor thiab LDR nyob rau hauv qhov chaw peb xav tau ntxiv qhov 'THIAB' ua haujlwm. Txhawm rau ua tiav qhov no kuv ntxiv lub hom phiaj dav dav PNP transistor. Thaum pom lub suab txav 'thiab' thaum lub hnub ci nyob ntawm qhov kev siv (kho los ntawm POT) tam sim no ntws tawm ntawm transistor. Ntawm no, peb yuav tsum ua kom nrov nrov tam sim no tau txais los ntawm tus sau ntawm PNP transistor thiab qhib thiab tua LED qhia thiab Relay. Lub hom phiaj dav dav NPN transistor tau siv los ua qhov no. Qhov ntawd yog txhua yam ua tiav.

Kauj Ruam 4: Kuv Tau Ua Dab Tsi

Yog li, qhov no yog qhov kuv tau ua.

Ntawm kuv lub rooj tsav xwm hauv vaj huam sib luag tau muag zoo nkauj heev nyob txhua qhov chaw, tab sis koj yuav nyiam kom lawv txhim kho kom zoo kom zoo me ntsis ntxiv. OK, yog li cia saib seb qhov no ua haujlwm li cas.

Kauj ruam 5: Demo

Yog lawm, Kuv tau muab lub rooj tsavxwm tso rau ntawm lub rooj no kom ua qhov ntsuas nrawm. Kuv tseem tsis tau teeb lub teeb pom kev zoo rau lub Circuit Court. Txawm li cas los xij, qhov ntsuas LED yuav tsum ua lub hom phiaj ntawm qhov ua qauv qhia no.

Yog li, tam sim no kuv yuav tsum tua lub teeb thiab ua rau chav tsaus ntuj. Cia saib seb lub ntsuas hluav taws xob tuaj yeem txav thiab teeb lub LED. Tada, nws ua haujlwm.

Tam sim no, cia qhib lub teeb ntawm chav thiab pom tias LED qhov taw qhia kaw lossis tsis yog. Yessss, uas ua haujlwm. OK, thaum kawg tsuas yog xav kom paub tseeb tias lub teeb pom kev tig tawm tom qab 30 vib nas this ntawm kuv txav tawm ntawm lub ntsuas qhov sib thooj. Boom, thiab qhov ntawd xaus qhov haujlwm. Tam sim no kuv tuaj yeem nruab nws ntawm lub qab nthab thiab ua rau kuv tus khub zoo siab.

Hloov chaw kom muaj 2 txog 3 PIR sensors koj tuaj yeem siv ib qho thiab teeb tsa nws ntawm kaum ntawm phab ntsa. Txawm li cas los xij, qhov ntawd yuav xav tau kev sib txuas me ntsis ntawm sab hauv lub ru tsev lossis saum qab nthab, uas yuav yog txoj kev kim dua thiab txaus siab tshaj li kev teeb tsa 3 lub ntsuas qhov ntsuas d tso lub cuab yeej nruab nrab ntawm chav.

Koj tseem tuaj yeem sib pauv Arduino nrog NodeMCU pawg thawj coj thiab ua cov ntaub ntawv deb nkag mus rau lub sijhawm thaum lub ntsuas pom pom lub suab lossis thaum lub teeb ci mus rau sau thaum tib neeg nkag mus rau hauv koj lub nkas -las thiab ntev npaum li cas lawv nyob hauv.

Kauj Ruam 6: Cov Cheeb Tsam ntawm Kev Siv PIR Sensors

Qhov teeb tsa no tuaj yeem siv rau:

* Automate Txhua Lub Teeb Sab Nraud

* Automate Lights of Basement, Garden or Covered Parking Areas

* Automate Lift Lobby lossis Cov Teeb Staircases

* Siv lub txaj los yog lub teeb hmo ntuj

* Tsim Smart Home Automation & Kev Ruaj Ntseg thiab ntau ntxiv..

Kauj ruam 7: Ua tsaug
