Cov induction keyboards feem ntau muaj xws li infrared induction keyboards, microwave induction keyboards, ultrasonic induction keyboards, piezoelectric induction keyboards, electromagnetic induction keyboards, thiab capacitance induction keyboards. Cov ntawv no tsuas yog piav qhia txog tib neeg infrared ntse sensor hloov, uas yog tus hloov uas cia li pib thaum ib tus neeg dhau ntawm thaj chaw infrared sensor kuaj pom.
Lub induction hloov yog hais txog tib neeg lub cev infrared ntse induction hloov, uas yog tus hloov hluav taws xob ua haujlwm tau txais thaum muaj ib tus neeg dhau ntawm thaj chaw infrared induction nrhiav thaj chaw. Lub ntsiab ntawm cov tib neeg lub cev infrared induction hloov yog tib neeg lub cev pyroelectric infrared sensor. Tib neeg lub cev muaj qhov kub ntawm lub cev tsis tu ncua, feem ntau li ntawm 37 degrees, yog li nws tawm ntawm duab teeb ci duab hluav taws xob nrog qhov tshwj xeeb txog ntab ntev li ntawm 10 μm. Kev sojntsuam passive infrared ua haujlwm los ntawm kev kuaj pom txog 10 μm ntawm infrared rays los ntawm tib neeg lub cev. Txog 10 μm ntawm infrared lub teeb tawm los ntawm tib neeg lub cev yog txhim kho los ntawm kev ua kom zoo nkauj Fresnel lim thiab tsom mus rau infrared sensing qhov chaw. Infrared induction qhov chaw feem ntau siv cov ntsiab pyroelectric. Cov ntsiab lus no poob lawv qhov nqi sib npaug thaum lawv tau txais qhov hloov pauv ntawm qhov ntsuas kub ntawm tib neeg lub cev infrared tawg, tso lawv cov nqi tawm sab nraud, thiab cov kab hluav taws xob txuas ntxiv tuaj yeem cuam tshuam kev hloov pauv tom qab kuaj thiab ua. Yog tias tus neeg tsis tawm ntawm txoj kev hnov ntau, lub pob taws yuav raug muab txuas tas li; tom qab tus neeg tawm mus lossis tsis muaj kev nqis tes ua haujlwm ntev nyob rau thaj chaw hnov, qhov hloov yuav txiav tawm lub nra tom qab kev ncua.
Kev ntsuas ntawm kev thov ntawm lub tshuab tsis siv neeg lub cev infrared sensor hloov Cov khoom lag luam tsim nyog rau kev siv lub teeb pom kev zoo, ua pa, thiab lwm yam hauv txoj kev hauv tsev, chaw hauv tsev, chaw rau khoom, chaw tso tsheb, qab daus, chav dej thiab lwm qhov chaw. Nws yeej xav txog qhov kev hloov kho ntawm kev txawj ntse thiab kev tswj hwm vaj tse.
