Txoj Cai Ua Haujlwm ntawm Sensor Chips
Sensor chips hloov cov khoom siv lub cev rau hauv cov teeb liab hluav taws xob los ntawm kev siv lub cev tshwj xeeb lossis cov khoom siv. Cov hauv qab no yog cov hauv paus ntsiab lus ua haujlwm ntawm ntau yam khoom siv sensor chips:
Siab Sensor
Lub siab sensors yog ua raws li cov txheej txheem kev siv tshuab, ntsuas qhov siab los ntawm kev ntsuas qhov ntsuas ntawm elastic deformation ntawm cov khoom hauv qab quab yuam. Lawv feem ntau muaj piezoresistive, piezoelectric, lossis capacitive sensors. Thaum raug rau sab nraud, qhov kev tiv thaiv, kev them nqi, lossis lub peev xwm hauv lub sensor hloov raws li, tsim hluav taws xob teeb liab.
Kub Sensor
Kub sensors siv qhov kub thiab txias -sensitive zog ntawm cov ntaub ntawv los ntsuas ambient kub. Feem ntau hom yog thermistor thiab thermocouples. Qhov kev tiv thaiv ntawm lub thermistor hloov nrog qhov kub thiab txias, thaum lub thermocouple tso siab rau qhov sib txawv uas tsim los ntawm qhov kub ntawm qhov sib txawv ntawm cov hlau sib txawv.
Optical Sensor
Optical sensors siv qhov rhiab heev ntawm cov ntaub ntawv photosensitive rau lub teeb teeb liab los ntsuas lub teeb siv, lub teeb zaus, thiab lwm yam. Cov khoom siv kho qhov muag muaj xws li photoresistors, photodiodes, thiab fiber optic sensors. Thaum lub teeb ci rau ntawm lub sensor, nws qhov tsis kam, tam sim no, lossis qhov hloov hluav taws xob, yog li ntsuas lub teeb siv los yog lwm yam khoom siv kho qhov muag.
Accelerometer Sensors
Accelerometer sensors ntsuas qhov nrawm ntawm ib qho khoom hauv qhov chaw thiab feem ntau yog tsim los ntawm microelectromechanical systems (MEMS) technology. Lawv ua raws li cov nyhuv inertial ntawm huab hwm coj nyob rau hauv kev quab yuam, ntes acceleration los ntawm kev ntsuas feeb ntawm kev hloov pauv lossis cov teebmeem electrostatic. Cov sensors no tuaj yeem siv rau hauv cov khoom siv xws li tsheb kev nyab xeeb, smartphones, thiab game controllers.
Gas Sensors
Gas sensors yog siv los ntsuas qhov concentration ntawm cov pa roj hauv ib puag ncig. Lawv feem ntau yog raws li cov qauv tshuaj tiv thaiv, ntsuas qhov muaj thiab qhov siab ntawm lub hom phiaj roj los ntawm cov ntaub ntawv rhiab uas cuam tshuam nrog nws. Piv txwv li, cov khoom siv hluav taws xob siv hluav taws xob siv cov tshuaj tiv thaiv redox kom pom cov roj concentration, thaum cov khoom siv kho qhov muag siv cov teebmeem xws li nqus, tawg, lossis luminescence.
