Niaj hnub no, cov neeg hlau tuaj yeem pom nyob txhua qhov chaw hauv peb lub neej txhua hnub. Muaj ntau hom neeg hlau, xws li kev lag luam neeg hlau, kev pabcuam neeg hlau, tshuaj xyuas neeg hlau, kev tiv thaiv kabmob sib kis, thiab lwm yam. Lawv cov koob npe tau coj kev yooj yim rau peb lub neej. Ib qho ntawm cov laj thawj vim li cas cov neeg hlau tuaj yeem siv tau zoo yog tias lawv tuaj yeem pom sai thiab raug pom thiab ntsuas qhov chaw ib puag ncig thaum tsiv, zam kev sib tsoo nrog cov teeb meem lossis tib neeg, thiab ua rau tsis muaj nyiaj txiag poob lossis kev nyab xeeb ntawm tus kheej.
Nws tuaj yeem raug zam kom tsis txhob muaj teeb meem thiab mus txog qhov chaw zoo vim tias muaj ob lub qhov muag "qhov muag" nyob rau hauv pem hauv ntej ntawm tus neeg hlau - ultrasonic sensors. Piv nrog rau qhov sib txawv ntawm infrared, lub hauv paus ntsiab lus ntawm kev sib txawv ultrasonic yog yooj yim dua, vim hais tias lub suab nthwv dej yuav tshwm sim thaum ntsib teeb meem, thiab qhov ceev ntawm lub suab nthwv dej yog paub, yog li koj tsuas yog xav paub lub sijhawm sib txawv ntawm kev sib kis thiab kev txais tos, koj tuaj yeem ua tau. yooj yim xam qhov ntsuas qhov deb, thiab tom qab ntawd muab cov kis tau tus mob Qhov kev ncua deb ntawm lub receiver thiab receiver tuaj yeem xam qhov deb ntawm qhov teeb meem. Thiab ultrasonic muaj peev xwm nkag mus rau cov kua thiab cov khib nyiab, tshwj xeeb tshaj yog nyob rau hauv cov khib nyiab opaque, nws tuaj yeem nkag mus rau qhov tob ntawm kaum ntawm meters.
Ultrasonic obstacle zam sensor A02 yog ib tug high-resolution (1mm), high-precision, low-power ultrasonic sensor. Hauv kev tsim, nws tsis tsuas yog cuam tshuam nrog kev cuam tshuam lub suab nrov, tab sis kuj muaj peev xwm tiv thaiv lub suab nrov cuam tshuam. Ntxiv mus, rau lub hom phiaj ntawm qhov ntau thiab tsawg thiab qhov hloov pauv hluav taws xob hloov hluav taws xob, kev them nyiaj rhiab heev yog ua tiav. Tsis tas li ntawd, nws kuj muaj cov txheej txheem kub kub them nyiaj, uas ua rau cov ntaub ntawv ntsuas qhov deb ntau dua. Nws yog ib qho kev daws teeb meem zoo rau cov chaw sab hauv tsev!
Ultrasonic obstacle zam sensor A02 Nta:
Qhov loj me thiab cov nqi qis
Kev daws teeb meem siab txog li 1 hli
Ntsuas qhov deb mus txog 4.5 meters
Ntau txoj kev tso zis, suav nrog mem tes dav, RS485, serial chaw nres nkoj, IIC
Kev siv hluav taws xob tsawg yog tsim rau cov roj teeb uas siv hluav taws xob, tsuas yog 5mA tam sim no rau 3.3V fais fab mov
Kev them nyiaj rau qhov hloov pauv loj hauv lub hom phiaj thiab kev ua haujlwm voltage
Standard internal kub them nyiaj thiab xaiv sab nraud kub them nyiaj
Kev khiav hauj lwm kub ntawm -15 ℃ + 65 ℃
