Passive infrared sensor (PIR sensor) yog lub tshuab hluav taws xob ntsuas ntsuas infrared (IR) lub teeb ci los ntawm cov khoom hauv nws qhov kev pom. Lawv feem ntau siv hauv PIR-based motion detectors. PIR sensors feem ntau siv hauv kev ceeb toom kev nyab xeeb thiab kev siv teeb pom kev zoo tsis siv neeg. PIR sensors pom kev txav mus los dav, tab sis tsis qhia cov ntaub ntawv ntawm leej twg lossis qhov twg tau tsiv mus. Rau lub hom phiaj ntawd, yuav tsum muaj lub ntsuas hluav taws xob zoo IR.

Kauj ruam 1: Txoj kev xav

PIR sensors feem ntau hu ua "PIR", lossis qee zaum "PID", rau "passive infrared detector". Lub sij hawm passive hais txog qhov tseeb tias PIR cov cuab yeej tsis ua hluav taws xob rau lub hom phiaj tshawb nrhiav. Lawv ua haujlwm tag nrho los ntawm kev tshawb pom hluav taws xob hluav taws xob (hluav taws xob cua sov) tawm los lossis cuam tshuam los ntawm cov khoom.

Pin 1 - GND Pin 2 - Pin Output 3 - VCC (+5V) Hom Kev Ua Haujlwm

Qhov ntsuas no muaj ob hom kev ua haujlwm:

1. Ib Hom Ua Rau Kom Xaiv Ib Hom Ua Haujlwm, teeb tsa jumper ntawm PIR sensor yuav tsum tau teeb tsa LOW. Nyob rau hauv Ib Leeg Hom Hom, Cov Zis Tawm mus HIGH thaum pom cov lus tsa suab. Tom qab kev ncua sijhawm tshwj xeeb qhov tso tawm mus rau LOW txawm hais tias lub hom phiaj yog nyob rau hauv tsab ntawv tsa suab. Cov zis yog LOW rau qee lub sijhawm thiab rov mus HIGH yog tias cov khoom tseem nyob hauv kev txav. Qhov kev ncua no yog muab los ntawm cov neeg siv siv lub zog ntsuas. Lub hwj chim no nyob ntawm pawg PIR sensor module. Ua li no, PIR sensor muab HIGH/LOW pulses yog tias cov khoom nyob hauv kev txav mus tas li.

2. Rov Ua Kom Rov Ua Haujlwm Kom xaiv Rov ua dua hom, teeb tsa jumper ntawm PIR sensor yuav tsum tau teeb tsa ntawm HIGH. Yog tias Rov Ua Haujlwm Hom Rov Ua Dua, Cov Tawm Tawm mus HIGH thaum pom cov lus tsa suab. Cov zis ntawm PIR sensor yog HIGH kom txog thaum cov khoom txav mus. Thaum cov khoom tsis txav, lossis ploj mus los ntawm thaj chaw ntsuas, PIR txuas ntxiv nws lub xeev HIGH txog qee qhov kev ncua qeeb (tsel). Peb tuaj yeem muab qhov kev ncua no (tsel) los ntawm kev kho lub zog ntsuas. Lub hwj chim no nyob ntawm pawg PIR sensor module. Hauv txoj kev no, PIR sensor muab HIGH mem tes yog tias cov khoom nyob hauv kev txav mus tas li.

Hloov Kev Ruaj Ntseg thiab Ncua Sijhawm

Muaj ob lub hwjchim ntawm PIR tsab ntawv tsa suab lub rooj tsavxwm: Hloov kho lub siab thiab hloov sijhawm ncua. Nws muaj peev xwm ua kom PIR nkag siab ntau dua lossis Tsis Rhuav Siab Txaus. Qhov siab tshaj plaws tuaj yeem ua tiav txog 6 meters. Lub Sijhawm Ncauj Sijhawm Kho lub hwj chim siv los kho lub sijhawm teev tseg uas qhia hauv kab duab. Clockwise Movement ua rau PIR nkag siab dua. Ob yam tseem ceeb thaum tsim PIR sensor: Tus nqi qis thiab Siab Zoo. Ob yam no tuaj yeem ua tiav los ntawm kev siv Lens cap. Cov lo ntsiab muag ua haujlwm ntau ntxiv; ua kom muaj kev nkag siab zoo thiab hloov pauv kev nkag siab sib txawv yooj yim.
