    Mfundo Yogwira Ntchito ya Thermopile Infrared Sensor - Thermoelectric Effect

    Thermoelectric Zotsatira (Seebeck Zotsatira)

    Ngati zida ziwiri zosiyana kapena zinthu A ndi B zomwe zimakhala ndizofanana mukamagwira ntchito zosiyanasiyana, zikalumikizidwa kumapeto otentha (Hot Junction Area), zotsegulidwa kumapeto ozizira (Cold Junction Area), ndi kutentha kwapakati pakati pa yotentha kumapeto ndi kuzizira kumapeto ndi coldTHC, kotero kumapeto ozizira padzakhala mphamvu yamagetsi yamagetsi Vkunja.

    Pamene radiation ya infrared yakunja imawunikira malo oyamwa a chowunikira, malowo amayamwa ma radiation a infrared ndikusandutsa mphamvu yotentha. Makina otenthetsera kutentha amapangidwa mdera lotentha komanso malo ozizilirapo ozizira. Kudzera pa Seebeck Effect ya thermocouple zakuthupi, kutentha kwakanthawi kumatha kusandulika kukhala chizindikiro chamagetsi.

    Thermoelectric Zotsatira (Seebeck Zotsatira)

    Sefani (mawonekedwe a fyuluta ya IR ndiyotheka): sankhani gulu la infrared, pewani mawonekedwe ena owala kuti akhudze sensa

    Kapu: mawonekedwe othandizira a fyuluta ya IR

    TPS Chip: kuzindikira chizindikiro cha infrared chomwe chimadutsa mu fyuluta ya IR

    Chamutu: mawonekedwe othandizira chip

    Chip Thermistor (Chosankha): kuwunika kutentha kwa mphambano yozungulira ya TPS chip

    ASIC processing dera chip (ngati mukufuna, kutulutsa chizindikiro): kukonza chizindikiritso cha analog cha TPS chip

    Titha kuwona kuti njira yogwiritsira ntchito kachipangizo kachipangizo kachipangizo kotchedwa thermopile sensor ndi kutembenuza kawiri kwama "light-thermal-magetsi". Chinthu chilichonse pamwamba pa zero (kuphatikiza thupi la munthu) chimatulutsa kuwala kwa infrared, ngati mungasankhe kutalika kwa mawonekedwe ake kudzera mu fyuluta ya infrared (5-14μm band window), pomwe zinthu zazing'ono zamkati pa chip zimayatsa kutentha kwapakati ndikusintha kuyatsa kukhala kutentha , zomwe zimapangitsa kukula kwakutentha kwa dera loyamwa, kusiyana kwa kutentha pakati pa malo oyambira ndi malo ozizira olumikizana ndikusandulika kukhala kotulutsa mphamvu zamagetsi kudzera ma cell mazana angapo a ma thermocouples angapo olumikizana, ndipo chizindikiritso cha infrared chimapezeka pambuyo poti magetsi akutuluka kwaiye.

    Kuwona kuchokera pamapangidwe, kachipangizo kakang'ono kotchedwa Sunshine Technologies's infrared sensor ndikosiyana ndi zinthu wamba, kapangidwe kake ndi "kopanda pake". Pali vuto lalikulu laukadaulo kwa kapangidwe kameneka, ndiye kuti, momwe mungayikitsire kanema wa 1μm wandiweyani woyimilira pamalo a 1 mm yokha2, ndikuwonetsetsa kuti kanemayo akhoza kukhala ndi chiwonetsero chokwanira kuti atembenuzire kuwala kwa infrared kukhala chizindikiro chamagetsi, kuti akwaniritse mphamvu zamphamvu zama sensa. Ndi chifukwa chakuti Sunshine Technologies yakhala ikugonjetsa luso laukadaulo ili lomwe lingathe kusokoneza nthawi yayitali zinthu zakunja kamodzi kokha.
