Iyo Yekushanda Nheyo yeThermopile Infrared Sensor - Thermoelectric Effect

Thermoelectric Effect (Seebeck Effect)

Kana zvinhu zviviri zvakasiyana kana zvinhu A uye B zvine chinhu chimwe chete iine basa rakasiyana, kana yakabatana panopisa (Hot Junction Area), yakavhurwa panotonhora kupera (Cold Junction Area), uye tembiricha pakati pekupisa. kuguma uye kutonhora kupera ndiko ΔT_HC, saka panotonhora pachange paine thermoelectromotive force V_kunze.

Kana iyo yekunze infrared mwaranzi inovhenekera nzvimbo yekunyura ye detector, nzvimbo yekunyura inotora iyo infrared radiation uye inoishandura kuita kupisa simba.Iyo tembiricha gradient ichagadzirwa munzvimbo inopisa yejinji uye inotonhora nzvimbo yekusangana.Kuburikidza neSeebeck Effect ye thermocouple zvinhu, tembiricha gradient inogona kushandurwa kuita voltage chiratidzo kuburitsa.

Thermoelectric Effect (Seebeck Effect)

Sefa(hunhu hweIR sefa ndeyekusarudza): sarudza infrared bhendi, dzivirira imwe wavelength yechiedza kukanganisa sensor.

Cap: iyo inotsigira michina chimiro che IR sefa.

TPS Chip: kunzwa iyo infrared siginecha inopfuura nepaiyo IR sefa.

Header: iyo inotsigira mechanical chimiro che chip.

Chip Thermistor(Sarudzo): tarisisa kutonhora kwenzvimbo yekudziya tembiricha yeTPS chip.

ASIC processing circuit chip(inosarudzika, inomisikidza chiratidzo chinobuda): kugadzirisa iyo analog inobuda chiratidzo cheTPS chip.

Zvinogona kuonekwa kuti nheyo yekushanda ye thermopile sensor chip ndiyo inoshandura kaviri yemuviri we "light-thermal-electricity".Chero chinhu chiri pamusoro pe zero yakakwana (kusanganisira muviri wemunhu) chinoburitsa mwaranzi ye infrared, kana ukasarudza wavelength yakakodzera kuburikidza ne infrared sefa (5-14μm bhendi hwindo), kana infrared inonzwa zvinhu pa chip inotora infrared kupisa uye kushandura mwenje kuita kupisa. , zvichikonzera kukwira kwekushisa kwenzvimbo yekunyura, musiyano wetembiricha pakati penzvimbo yekunyura uye inotonhora yejoni inoshandurwa kuita voltage inobuda kuburikidza nemazana emaseti e micro thermocouples akateedzana yekubatanidza, uye infrared chiratidzo chinoonekwa mushure mekubuda kwevoltage. generated.

Kuona kubva pachimiro, iyo Sunshine Technologies's thermopile infrared sensor yakasiyana kubva kune zvakajairwa zvigadzirwa, chimiro chayo "chisina kunze".Iko kune yakakosha tekinoroji kuomerwa kwechimiro ichi, ndiko kuti, nzira yekuisa dhizaini ye1μm gobvu rekumiswa firimu panzvimbo ye1 mm chete.², uye ive nechokwadi chekuti firimu rinogona kuva neshanduko yakakwana yekushandura mwenje we infrared mumagetsi emagetsi kubuda, kuitira kuti isangane nezvinodiwa zvesimba rechiratidzo che sensor.Izvo chaizvo nekuti iyo Sunshine Technologies yakakunda uye kugona iyi yakakosha tekinoroji iyo inogona kuputsa iyo yakareba monopoly yezvigadzirwa zvekunze panguva imwe chete.
