Lub ntsiab ntawm cov infrared sensor hloov yog pyroelectric infrared sensor. Tib neeg lub cev muaj qee qhov kub ntawm lub cev, feem ntau yog 36-37 degrees, yog li nws tawm ntawm duab teeb ci duab hluav taws xob ntawm lub teeb yoj ib qho. Lub 9,5um infrared rays ua tawm los ntawm tib neeg lub cev yog txhim kho los ntawm lub iav Fresnel kom sau cov duab infrared. Raws li rau qhov induction qhov chaw, qhov khoom siv infrared induction feem ntau adopts pyroelectric infrared sensor. Hom kev sib tw no yuav plam qhov them tus nqi sib npaug thaum qhov ntsuas kub ntawm infrared tawg ntawm tib neeg lub cev hloov, thiab tus nqi yuav tawm sab nraud. Lub voj voos txuas tom qab tuaj yeem ua rau hloov mus tom qab ntsuas pom thiab ua tiav.
Nruab thiab siv
1. Thaum lub sijhawm teeb tsa, tsis pub tso xaim nyob hauv, thiab thauj cov xov hluav taws xob luv yog txwv tsis pub. Rau cov khoom uas tswj cov teeb roj fluorescent thiab lub teeb txuag hluav taws xob, nws yuav siv sijhawm li 30 mus rau 60 lub sijhawm rau qhov hluav taws xob sab hauv los tsim lub sijhawm rau tus hloov mus ua haujlwm ib txwm muaj thaum lub zog thawj zaug.
2. Vim tias qhov loj pib tam sim no ntawm lub teeb roj fluorescent thiab lub teeb txuag hluav taws xob, nws raug nquahu kom ib qho hloov hluav taws xob tswj tsawg dua 2 nra.
3. Tsis txhob nruab qhov khoom nyob rau hauv qhov chaw uas muaj cua kub hloov mus rau. Yog hais tias tus tswj load yog cua sov, nws yuav tsum siab tshaj 1 'meter'.
4. 2-hlau xov tsis muaj kab nruab nrab thiab kev tswj xwm ceev tsis tas yuav txiav txim siab lub xov tooj hluav taws xob polarity. Cov khoom lag luam nrog kev tswj thaum muaj xwm ceev lossis kab nruab nrab yuav tsum muaj xaim raws li qhia hauv daim duab (tsis muaj khoom tswj hwm thaum muaj xwm ceev EM lub dav hlau tsis muaj xaim).
5. Thaum kho lub teeb tswj lub teeb pom kev zoo thiab lub sijhawm qeeb lub pob qhov rooj, koj yuav tsum siv lub zog nruab nrab. Kev siv lub zog ntau dhau yuav ua rau cov khoom puas.
