1.Whakarongo
Ko te S001F2443 whakauruhia te pyroelectric pyroelectric pyroelectric e whakamahi ana i te lihium hou taiao
Tantalate (litae₃) nga rauemi karaihe-kotahi mo tana waahanga ahua. Ko te 4-pin mamati pi ahi mura ahi
e whakakotahi ana i te maramara tohu tohu tohu (ic) me te mea nui i roto i te electromagnetic
hipoki hipoki. Ka whakawhitiwhiti te kaiwhakaari me te kaiwhakahaere o waho hei whirihora i nga momo
Whenua whakahaere. Ko te huānga feensing te tohu Flame Flicker ki te tohu mamati
Ko te kaupapa iC na roto i te waahanga whakaurunga rerekee-tino rereke. Ko te hurihuri miihini mamati
Ko te tohu ki te whakatakotoranga mamati ma te 14-bit adc, e pai ana ki te tukatuka i te tukatuka tohu me te arorau
Ko te mana whakahaere penei i te maaramatanga o te kitenga (Trigger Triger), te wa matapo i muri i te kaiwhakamaori i muri mai i te atanga whakawhitiwhiti kotahi. I roto i nga mahi e mau tonu ana te ahi, kaore e hiahiatia ana e te μc kia noho kaha (ka uru atu ki te aratau tuuturu ki te whakaora mana). I te wa e kitea ana e te kaiwhakaari mamati he tohu tohu flacker i mua i te raarangi i mua i te raarangi o te a-roto e tuku ana i te ahuru int / docI, e akiaki ana i te mahi whakahaere. I runga ano i te aratau whakahaere whirihoranga, ka taea hoki e te μc te panui i te uara tohu mamati mai i te kaupapa o te mahi a te Doci. Ko te otinga whakahaere-whai hua e waatea ana.
2.Tohu
1.digital te tukatuka tohu me te whakawhitiwhiti korero mo te kaiwhakahaere;
2. Ko nga tikanga o te kitenga me te tautoko mo nga momo whakahaere rereke e toru, te whakahohe i nga putanga o te ahi e tuwhera ana me te mura o te ahi.
3.Whakaahua-i roto i te Tuarua Tuarua Tuarua Tuarua Tuarua mo te Sensor Panui, te wawaotanga whakauru mai i etahi atu waa;
4.Ko te huringa tohu o te tohu kua oti te whakauru i roto i te taupoki o te whakangungu hiko, me te aukati i nga titi me te aukati i te aukati ki te reo irirangi;
5.Ko te tikanga whakahaere o te punaha e tino arotau ana mo te kaha kaha, e tika ana mo nga taputapu hiko-hiko;
6.Power Whakaputanga Taha me te kitenga pāmahana pāmahana;
7.operates me te whakapakaritanga tere i muri i te tirotiro i te waa-ake;
8.Whakaahia nga taonga o te riipene a-taiao, e piri ana ki nga whakaritenga o te taiao a ROHS me te kore e hiahia ki nga tohu tiwhikete ranei.
3.Application
1. Roro nga kaitirotiro ahi tuwhera;
2. Kaitoi ahi;
3. Ipurangi o nga mea e pa ana ki te taputapu taputapu;
4. Nga whakaoho ahi mo nga kaainga, nga tipu tipu, me nga wheketere.
4. Nga tohu mahi
4.1 Whakatauranga teitei
Ko te tino rangatira o te hiko nui rawa atu i te teepu i raro nei ka pakaru te kino o te taputapu. Ko te mahi i tua atu i nga ahuatanga kua tino paahitia pea ka pa ki te pono o te taputapu.
