Kev Tshawb Fawb Kev Kho Mob ntawm Sensor -} based so rooj hauv cov chav dej hauv zej zog

Thawj tiam: Ib Leeg Sensor TRIGGER (2000-2010). Cov khoom thaum Ntxov tau nyob ib puag ncig "infrared sensing + kev ua haujlwm kho tshuab," muab cov haujlwm yooj yim tsuas yog. Thaum ib tug neeg txav mus los, tus ntsuas hluav taws xob ua rau lub rooj zaum tso quav mus rau qhov qhib (rau cov txiv neej tso zis), thiab ncua kev kaw tom qab tus neeg sab laug. Cov ntsiab lus hais tau mob tau tseem ceeb: qhov tsis txaus ntseeg tau yooj yim rau kev puas tsuaj los ntawm kev puas tsuaj rau kev puas tsuaj los ntawm cov dej phwj tuaj thiab cov khoom sib txawv thiab txawv teb chaws.

Qhov no ua rau "muaj txiaj ntsig -}}} Tsuas yog lub hau ci ntsa iab los ua ke thaum tus poj niam lossis tus neeg zaum zaum. Tsis tas li ntawd, lub tsev dej nyab tshiab thiab muaj ipx4 lossis rov qab los ntawm kev poob siab (txuas ntxiv rau lub neej thaum 10,000 qhib thiab kaw mus rau ntau tshaj 50,000.

Thib peb tiam: kev sib koom ua ke thiab cov ntaub ntawv -}} {{{3}- tam sim no. Nrog rau kev nkag mus hauv Is Taws Nem ntawm yam (iot), sensor {{5} {Ua kom tiav cov chav dej "ntse tswj hwm." Cov no suav nrog ua - hauv cov xwm txheej kub thiab cov ntaub ntawv siv sijhawm (piv txwv li cov ntaub ntawv siv nyiaj txiag, pab kev saib xyuas cov neeg ua haujlwm nrog kev soj ntsuam kom meej. Qee qhov qauv high-kawg kuj tseem muaj kev tshuaj xyuas ultraviolet (ua tiav cov neeg siv khoom tsis muaj menyuam ntawm 99.Txhua kev ua kom muaj zog (ua tiav cov haujlwm ntse tshaj plaws thiab kev tswj hwm.
