Imanuwali yomsebenzisi ye-SL-W-TRS-5.5Dx Digital Infrared Thermopile Demo Board

SLKOR I-Micro Semicon Co., Ltd. inomgogodla wayo wezobuchwepheshe ovela eNyuvesi yaseTsinghua kanye neNyuvesi yaseYonsei eNingizimu Korea. Ihola ukuthuthukiswa kwenkampani ngezinto ezintsha, izinqubo ezintsha kanye nemikhiqizo emisha, futhi ikwazi kahle ubuchwepheshe obuthuthuke emhlabeni wonke besizukulwane sesithathu semiconductor silicon carbide power devices kusenesikhathi uma kuqhathaniswa.

 

SLKOR iyibhizinisi lobuchwepheshe obuphezulu elihlanganisa ukuklama, ukuthuthukiswa, ukukhiqizwa nokuthengiswa kwemikhiqizo ye-elekthronikhi. Ihlinzeka amakhasimende ngemikhiqizo enokwethenjelwa kanye nezinsizakalo zobuchwepheshe ezihambisanayo. Ibhrendi "SLKOR"Ithuthuke kancane kancane yaba edume umhlaba wonke, inikezela ngemikhiqizo nezisombululo kumakhasimende angaphezu kuka-10,000 emhlabeni jikelele.

 

Emzamweni wokulwela ukunikeza amakhasimende uhla olugcwele lwemikhiqizo ehambisanayo, SLKOR yethule uchungechunge lwezincwadi zokusebenzisa amabhodi edemo wemiklamo yezinhlelo zokusebenza zokulinganisa izinga lokushisa le-infrared thermopile okungezona okuthintana nalo.

 

1.1 Igama: Incwadi Yomsebenzisi ye SLKOR Ibhodi Ledemo Yesicelo Sokukala Isilinganiso Sokushisa Kwedijithali ye-Infrared Infrared Thermopile

Izicelo: Imishini egqokekayo ehlakaniphile, amafoni ahlakaniphile, ukuqapha izinga lokushisa kwezimboni, ukukalwa kwezinga lokushisa komzimba womuntu okungathinteki, inzwa yokushisa ehlakaniphile nokulawula namanye amadivaysi anosayizi omncane wokulinganisa izinga lokushisa lebanga elifushane.

1.3 SL-W-TRS-5.5Dx Series Demo Board:

Isetshenziselwa ukuhlola nokuhlola izinhlobo ezahlukene zezinzwa. Imiphumela yokulinganisa izovezwa esikrinini futhi ingaphrintwa kusofthiwe ye-serial yokulungisa iphutha lembobo ku-PC nge-USB kuya kumbobo ye-serial. Incazelo yenkinobho: Inkinobho yangakwesokunxele eyokusethwa kabusha, futhi inkinobho yesokudla ingalawula ukuqala nokumiswa kohlelo.

 

2. Idizayini yezingxenyekazi zekhompuyutha ye-SL-W-TRS-5.5Dx Series

 

Izikhonkwane ze-chip zihlanganisa ukunikezwa kwamandla kanye nebhasi ye-I2C, enenani lamaphini angu-4. Ibanga elivumelekile le-voltage yokuhlinzeka ngu-2.3 - 3.6V. Inzwa ngokwayo inokusetshenziswa kwamandla okuphansi kakhulu. I-capacitor engu-0.1uF phakathi kwendawo yokunikeza amandla yanele. Uma inzwa ikude kakhulu nengxenye yokuphakelwa kwamandla, i-capacitor eyengeziwe engu-10uF ingacatshangelwa ukuze kuqinisekiswe ukunikezwa kwamandla okuzinzile nokunciphisa umsindo.

 

 

 

3. Incazelo ye-SL-W-TRS-5.5Dx Series Demo Board

 

3.1 Ibhodi ledemo linikwa amandla isokhethi yohlobo C, futhi amandla kagesi ebhodi ledemo ngu-5V. Uma isetshenziswa, xhuma ibhodi ledemo ku-PC ngo-Type-C, bese ungakwazi ukubuka imiphumela esikrinini. Uma udinga ukukhombisa idatha ngembobo ye-serial, kudingeka ukuthi ufake uhlelo lomshayeli lwe-WCH CH340 bese usebenzisa isofthiwe ye-serial yokulungisa iphutha lembobo ukuze usebenze. Izilungiselelo zokuxhumana kwembobo yochungechunge zimi kanje: Izinga le-Baud: 9600, Amabhithi edatha: 8, Amabhithi wokumisa: 1, futhi akukho ukuhlola kokulingana.

 

3.2 Ukuboniswa kwesikrini kwebhodi ledemo ukusuka phezulu kuye phansi kungokulandelayo: izinga lokushisa le-ambient (tamb), i-sensor output voltage (vtp_cor), izinga lokushisa lento (engaphezulu) (tobj), kanye nezinga lokushisa lomzimba womuntu (tbdy). Iyunithi yamanani okushisa angenhla ngu-°C, kanti iyunithi ye-voltage ingu-μV. Phakathi kwazo, amanani amathathu okuqala yimiphumela yasekuqaleni yedivayisi. Inani lokushisa komzimba libalwa ngokusekelwe kumanani okuqala kusetshenziswa i-algorithm yenkampani yethu futhi ingeyereferensi kuphela. Abasebenzisi bangacubungula idatha besebenzisa ama-algorithms abo okushisa komzimba ngokuya ngezidingo zabo. 

 

Umphumela wokuboniswa kwembobo ye-serial
