Qhov zoo ntawm Ultrasonic Sensors
Ultrasonic sensors muaj ntau zaus, siab rhiab heev, thiab muaj zog nkag; yog li ntawd, lawv tuaj yeem pom cov khoom sib sib zog nqus tau yooj yim. Cov sensors tuaj yeem txuas tau yooj yim rau microcontrollers lossis txhua hom kev tswj hwm. Cov sensors no muaj qhov tseeb dua li lwm txoj hauv kev los ntsuas qhov tuab thiab qhov tob ntawm qhov sib npaug. Cov sensors no tuaj yeem nkag siab qhov xwm txheej, cov duab, thiab kev taw qhia ntawm cov khoom tshwj xeeb hauv lawv cheeb tsam. Lawv yooj yim siv thiab tsis muaj kev phom sij rau cov khoom nyob ze, tib neeg, khoom siv, lossis cov khoom siv thaum ua haujlwm.
Disadvantages ntawm Ultrasonic Sensors
Thaum siv lub ntsuas ntsuas ultrasonic rau kev tshuaj xyuas, nws yog ib qho tseem ceeb kom nkag siab txog kev khiav hauj lwm phau ntawv; Hauv lwm lo lus, nws yuav tsum tau ua tib zoo saib xyuas ntawm tus kws tshaj lij kev paub. Txoj kev txhim kho thiab kev tshuaj xyuas cov cuab yeej siv cov cuab yeej siv ultrasonic yuav tsum muaj kev paub dav los ntawm cov kws tshaj lij tshuaj xyuas. Cov sensors no tuaj yeem siv rau kev tshuaj xyuas lub hom phiaj, tab sis lawv yuav tsum tsis muaj dej; txwv tsis pub, lawv tuaj yeem raug puas tsuaj. Interfacing cov sensors no nrog lub microcontroller lossis ib tus maub los yuav tsum muaj cov neeg ua haujlwm paub txog lossis cov programmers.
