Cov yam ntxwv tseem ceeb ntawm lub sensor feem ntau piav qhia txog kev sib raug zoo ntawm nws cov zis thiab cov tswv yim. Txij li thaum cov tswv yim tuaj yeem muab faib ua ob lub xeev yooj yim - zoo li qub thiab dynamic- cov yam ntxwv sensor sib txuas kuj tseem muaj ob hom: cov yam ntxwv zoo li qub thiab dynamic.
Nyob rau hauv cov xwm txheej zoo li qub, piv txwv li, thaum lub teeb liab tawm tswv yim tseem ruaj khov lossis hloov maj mam, kev sib raug zoo ntawm lub sensor cov zis thiab cov tswv yim tsim nws cov yam ntxwv zoo li qub.
Cov cim tseem ceeb rau kev ntsuas cov yam ntxwv zoo li qub ntawm lub sensor muaj xws li: ntsuas ntau yam, rhiab heev, kev daws teeb meem, linearity, hysteresis, repeatability, drift, thiab stability.
