Q: Kodi ultrasonic sensor ndi chiyani?
Masensa a Ultrasonic ndi zida zowongolera mafakitale zomwe zimagwiritsa ntchito mafunde omveka pamwamba pa 20,000Hz, zomwe zimapitilira kuchuluka kwa kumva kwa anthu, kuyeza ndi kuwerengera mtunda kuchokera ku sensa kupita ku chinthu chodziwika bwino.
Q: Kodi masensa a ultrasonic amagwira ntchito bwanji?
Sensa ili ndi transducer ya ceramic yomwe imagwedezeka pamene mphamvu yamagetsi ikugwiritsidwa ntchito. Kugwedezekaku kumakakamiza ndikukulitsa mamolekyu a mpweya m'mafunde omwe amayenda kuchokera kumaso a sensor kupita ku chinthu chomwe mukufuna. Transducer imatumiza ndi kulandira mawu. Kachipangizo kamene kali ndi ultrasonic sensor imayesa mtunda potumiza phokoso la phokoso, kenako "kumvetsera" kwa kanthawi, kulola kuti phokoso la phokoso lidutse pa chandamale, kenako ndikutumizanso.
Q: Ndi liti kugwiritsa ntchito masensa a ultrasonic?
Popeza masensa a ultrasonic amagwiritsa ntchito mawu ngati njira yopatsirana m'malo mwa kuwala, amatha kugwiritsidwa ntchito m'malo omwe ma sensor owoneka sangathe. Masensa a Ultrasonic ndi njira yabwino yodziwira zinthu zowonekera ndikuyesa mulingo, zomwe zimakhala zovuta kwa masensa azithunzi chifukwa cha kuwonekera kwa chandamale. Mtundu wa chandamale ndi/kapena kunyezimira sikukhudza masensa akupanga omwe amatha kugwira ntchito modalirika pamalo owala kwambiri.
Q: Ndiyenera kugwiritsa ntchito liti sensor ya akupanga, poyerekeza ndi sensor ya kuwala?
Masensa akupanga ali ndi mwayi pozindikira zinthu zowonekera, milingo yamadzimadzi, kapena zowoneka bwino kwambiri kapena zachitsulo. Masensa akupanga amagwiranso ntchito bwino m'malo achinyezi chifukwa madontho amadzi amatulutsa kuwala. Komabe, masensa a akupanga amatha kusinthasintha kutentha kapena mphepo. Ndi masensa owoneka bwino, mutha kukhalanso ndi kukula pang'ono, kuyankha mwachangu, ndipo nthawi zina, mutha kupanga kadontho kowoneka bwino pa chandamale kuti muthandizire kukonza kachipangizo.
