S001F24A43 Te Pawera-Ka utua Mamati Mamati Haumaru Pokarekare Whero PIR Pūoko mura

1.Tirohanga

Ko te S001F24A43 whakaurunga pukoro mura pyroelectric e whakamahi ana i te lithium hou mo te taiao.

tantalate (LiTaO₃) he mea kirikiri kotahi mo tana huānga rongo. He pukoro mura PIR mamati 4-titi

e whakauru ana i te maramara whakamaarama tohu mamati (IC) me te huānga tairongo i roto i te hikohiko

uhi whakamarumaru. Ka whakawhiti anga-rua te tirotiro me tetahi kaiwhakahaere o waho hei whirihora i nga momo rereke

āhua whakahaere. Ka honoa e te huānga tairongo te tohu karapa mura ki te tohu matihiko

te whakamaarama i te IC na roto i te ara iahiko urunga paheketanga tino teitei. Ka huri te maramara IC mamati

te tohu ki te whakatakotoranga matihiko ma te 14-bit ADC, hei whakahaere i te tukatuka tohu me te arorau o muri mai.

control.Configurations such as detection sensitivity (trigger threshold), blind time after trigger reset, signal pulse counting time window, algorithms, and the selection of three operating modes can be applied by the external controller (µC) through the single-wire communication interface (SERIN) to configure internal registers. I roto i nga wa o te mahi kare tonu te mura o te ahi, karekau te µC me noho hohe (ka taea te uru ki te aratau tatari ki te penapena hiko). Anake ka kitea e te rangahau matihiko he tohu karapa mura e tutaki ana ki nga tikanga keu kua whirihora i mua ka tukuna e te IC whakamaarama o roto he whakahau whakaoho haukoti ki te µC ma te atanga INT/DOCI, ka akiaki i te µC ki te whakahohe me te mahi i nga mahi mana o muri. I runga ano i te aratau whakahaere kua whirihorahia, ka taea e te µC te panui i ia wa, i te kaha ranei te panui i te uara tohu mura ahi mai i te tirotiro ma te tauranga DOCI, katahi ka whakatau i nga mahi whai muri i runga i tana algorithm kua whakamaheretia. Na te kaha o te whakamohio i te mana oho, he pai tenei punaha mohio mamati mo nga tono he nui nga whakaritenga mo te penapena hiko, ina koa ko te kaha o te kaha o te pākahiko, otira ko te kaha o te hikohikohikohikohiko. otinga e wātea ana.

2.Ahuatanga

1.Tukatuka tohu Mamati me te korero rua ki te kaiwhakahaere;

2. Ka taea te whirihora i nga ahuatanga whakaoho me te tautoko mo nga momo whakahaere rereke e toru, ka taea te whakaputa i nga hua aro turuki mura ahi me te whakaputanga raraunga tohu tohu mura-a-ADC;

4. Ko te ara iahiko whakamaarama tohu infrared kua kapi katoa ki roto i te uhi whakamarumaru hiko, me te mana me nga titi atanga mamati anake e kitea ana, e whakarato ana i te tino aukati ki te wawaotanga reo irirangi;

5. Ko te tikanga whakahaere o te punaha kua tino arotauhia mo te kaha o te hiko, kia pai ai mo nga taputapu hiko-hiko;

6.Power supply ngaohiko me te i runga i-kiripi pāmahana rapunga;

7.Ka mahi me te whakapumau tere i muri i te tirotiro whaiaro i te wa o te hiko-ake;

8.Ka whakamahi i nga rauemi mohio-taiao LiTaO₃, e tino whai ana ki nga whakaritenga taiao RoHS me te kore e hiahia ki te whakakore, ki te tohu RoHS ranei.

3.Te tono

1. Various tuwhera mura aroturuki;

2. Nga kaitirotiro ahi;

3. Ipurangi o nga mea taputapu rongo mura;

4. Nga whakaoho ahi mo nga kainga, nga tipu ahumahi, me nga wheketere.
