PIR sensors lossis Passive Infrared Sensors yog qee yam kev ntsuas uas pom pom hluav taws xob hluav taws xob. Txhua tus neeg muaj ntshav sov xws li tib neeg lossis tsiaj txhu tso tawm qee qhov ntawm IR hluav taws xob lossis cua sov uas tuaj yeem kuaj pom los ntawm IR cov ntsuas. Cov cuab yeej siv hluav taws xob IR tso tawm hluav taws xob IR thiab ntsuas qhov hluav taws xob pom. Yog tias muaj dab tsi nrog cua sov txav nruab nrab ntawm lub tshuab xa hluav taws xob thiab lub ntsuas cua, cov hluav taws xob tau cuam tshuam thiab lub teeb liab tau tshwm sim tab sis hauv Passive IR sensors, lawv tsis tso tawm ib qho IR kab teeb tab sis pom cov duab hluav taws xob tawg los ntawm sab nraud. Thaum ib yam khoom nyob hauv qhov pom ntawm lub sensor nws muab kev nyeem ntawv.
Hom IR sensors siv hauv kev siv tshuab feem ntau yog Pyroelectric motion detector type piv txwv li kev txav ntawm lub cev IR raug kuaj pom. PIR cov cuab yeej muaj lub lens convex uas tau tsim los sau cov hluav taws xob hluav taws xob los ntawm thaj chaw sib txawv. Feem ntau muaj ob khub ntawm lub ntsuas hluav taws xob uas pom IR hluav taws xob nyob ib puag ncig hauv ib puag ncig ib puag ncig lub teeb liab uas ua los ntawm ob qho tib si raug tso tseg tab sis thaum ib tus neeg nkag mus rau qhov tsis txaus ntseeg pom ib qho ntawm lub sensor yuav ntes hluav taws xob ntau dua li lwm qhov thiab qhov sib txawv teeb liab yog generated. Peb tuaj yeem siv lub teeb liab no los tsav lub transistor hloov pauv, MOSFET lossis txuas nrog siv lub tshuab hluav taws xob lossis siv ua lub tswv yim rau micro-maub los nyob ntawm daim ntawv thov.
Khoom siv
1) PIR sensor
2) 12v Relay ntsuas rau 250V AC, 7A
3) BC 547 lossis 2N7000 lossis sib npaug
4) Resistor 220 ohm peb lub hlis twg watt
5) 12v DC cov khoom siv hluav taws xob
6) Diode 1N4007
Kauj Ruam 1: TSEV KAWM NTAWV
Lub Circuit Court yog yooj yim zoo nkauj raws li qhia. Peb siv lub teeb liab los ntawm PIR sensor ua lub hauv paus pib kom qhib lub transistor ua tiav txoj hauv kev rau cov xa hluav taws xob. Yog li qhov kev xa tawm tau muaj zog los ntawm 12v cov khoom, vim li ntawd cov kab theem nkag yuav txuas nrog lub teeb raws li kev hloov pauv hloov mus rau nws ib txwm qhib txoj haujlwm.
Kauj ruam 2: PIR SENSOR
Lub Sensor ua haujlwm rau qhov ntsuas hluav taws xob ntawm 5-20V DC. Ib hom sib txawv uas ua haujlwm ntawm 230VAC kuj tseem muaj. Raws li cov ntaub ntawv cov ntaub ntawv lub sensor tuaj yeem txheeb xyuas qhov deb ntawm 7 metres thiab thaj chaw conical pom ntawm 110 degrees.
Qhov rhiab heev thiab ncua tuaj yeem hloov kho siv ob lub tshuab txiav. Qhov ncua sij hawm txhais tau tias yog lub sijhawm uas lub sensor yuav ua kom lub teeb liab tawm siab tom qab nws tau tshwm sim ib zaug. Lub sensor tuaj yeem ua haujlwm nyob rau hauv ob hom: Ib leeg lossis tsis rov ua dua thiab hom rov ua dua.
Hauv ib hom kev ntsuas lub ntsuas pom thaum pom tib neeg cov lus tsa suab thiab yuav nyob twj ywm rau lub sijhawm tau teev tseg los ntawm lub tshuab txiav qeeb (hais 20 vib nas this) tom qab 20 vib nas this cov zis yuav qis dua txawm tias tib neeg nyob tam sim no. Nws yuav rov ua rau rov qab mus rau siab/ON tom qab ob peb feeb (Lub sijhawm thaiv) yog tias tib neeg tseem nyob tam sim no. Lub sijhawm thaiv yog lub sijhawm uas lub ntsuas hluav taws xob qis dua tom qab nws tau tshwm sim ib zaug thiab thaum lub sijhawm nws xiam oob qhab lossis yuav tsis pom ib qho lus tsa suab (Los ntawm lub neej ntawd nws 3 vib nas this).
Hauv kev rov ua dua hom kev ntsuas yuav ua rau pom muaj kev txav ntawm tus neeg thiab yuav rov teeb tsa ncua sijhawm ncua kom txog thaum tus neeg tawm mus. Yog li tsuas yog tom qab 20 vib nas this (lossis li cas koj teeb tsa lub tshuab txiav qeeb) txij li tus neeg tau tawm mus, lub ntsuas cua yuav tso tawm qis.
Jumper teeb tuaj yeem siv los teeb tsa ntawm ob hom. Hauv qhov teeb tsa no peb siv Rov Ua dua hom.
Kauj Ruam 3: PCB Tsim
PCB tau tsim los hauv kev tsim qauv tiv thaiv tab sis txij li nws yog ib qho me me hauv Circuit nws tuaj yeem ua tiav siv daim npav tooj liab tsis siv PCB
Kauj Ruam 4: Tso nws tag nrho ua ke
Rau kev tshaj tawm ntxiv nrog rau PIR sensor peb xav tau DC lub zog siv. Roj teeb tsis pom zoo vim nws yuav ntws sai dua. Kuv siv 12V SMPS cov khoom siv hluav taws xob vim nws lub cev nyhav thiab kev cog lus.
Kev sib txuas yog yooj yim thiab ncaj nraim rau tom hauv daim duab thiab txhua yam nws yuav tsum tau ua kom haum rau hauv lub thawv loj loj thiab yuav tsum tau teeb tsa ntawm phab ntsa. Khaws lub lens/dome ntawm PIR tsom mus rau txoj hauv kev uas nws tuaj yeem kuaj pom muaj.
