Photosensitive sensor

Photosensitive sensor ndi sensor yabwino yamagetsi yomwe imatha kuwongolera kusintha kwa dera chifukwa cha kusintha kwa kuwala m'bandakucha ndi mdima (kutuluka ndi kulowa kwadzuwa).Sensa ya photosensitive imatha kuwongolera kutsegula ndi kutseka kwaNyali zowunikira za LEDmalinga ndi nyengo, nthawi ndi dera.M'masiku owala, kugwiritsa ntchito mphamvu kumachepetsedwa pochepetsa mphamvu zake zotulutsa.Poyerekeza ndi kugwiritsa ntchito nyali za fulorosenti, malo ogulitsira omwe ali ndi malo a 200 sqm amatha kuchepetsa kugwiritsa ntchito mphamvu ndi 53% kwambiri, ndipo moyo wautumiki ndi pafupifupi 50000 ~ 100000 maola.Nthawi zambiri, moyo wautumiki wa nyali zowunikira za LED ndi pafupifupi maola 40000;Mtundu wa kuwala ukhoza kusinthidwanso mu RGB kuti kuwalako kukhale kokongola kwambiri komanso kuti mlengalenga ukhale wogwira ntchito.

Sensa ya infrared

Sensor ya infrared imagwira ntchito pozindikira infrared yopangidwa ndi thupi la munthu.Mfundo yaikulu ndi yakuti: Nthawi 10 za kutuluka kwa thupi laumunthu μ Kuwala kwa infrared pafupifupi M kumalimbikitsidwa ndi lens ya Fresnel fyuluta ndikusonkhanitsidwa pa pyroelectric element PIR detector.Anthu akasuntha, malo otulutsa ma radiation a infrared asintha, chinthucho chimataya mphamvu, kutulutsa mphamvu yamagetsi ndikutulutsa ndalamazo kunja.Sensa ya infrared isintha kusintha kwa mphamvu ya radiation ya infrared kudzera mu lens ya Fresnel fyuluta kukhala chizindikiro chamagetsi, kutembenuka kwa Thermoelectric.Ngati palibe thupi la munthu lomwe likuyenda m'malo ozindikirika a chowunikira cha infrared, sensa ya infrared imamva kutentha kwakumbuyo kokha.Thupi la munthu likalowa m'dera lodziwikiratu, kudzera mu lens ya Fresnel, pyroelectric infrared sensor imamva kusiyana pakati pa kutentha kwa thupi la munthu ndi kutentha kwakumbuyo, Pambuyo posonkhanitsa chizindikiro, poyerekeza ndi deta yomwe ilipo mu dongosolo kuti iweruze. ngati wina ndi magwero a infrared alowa m'malo ozindikira.

LED Motion Sensor Kuwala

Akupanga sensa

Masensa a Ultrasonic, ofanana ndi masensa a infrared, akhala akugwiritsidwa ntchito kwambiri pozindikira zinthu zomwe zikuyenda m'zaka zaposachedwa.The akupanga sensa makamaka amagwiritsa ntchito Doppler mfundo kutulutsa mkulu-pafupipafupi akupanga mafunde kuti kuposa mmene thupi la munthu amaonera kudzera galasi oscillator.Nthawi zambiri, mafunde a 25 ~ 40KHz amasankhidwa, kenako gawo lowongolera limazindikira kuchuluka kwa mafunde omwe amawonekera.Ngati pali kusuntha kwa zinthu m'derali, mafunde owoneka bwino amasinthasintha pang'ono, ndiye kuti, Doppler effect, kuti aweruze kayendetsedwe ka zinthu m'dera lounikira, kuti athe kuwongolera kusintha.

Sensa ya kutentha

Kutentha kachipangizo NTC chimagwiritsidwa ntchito ngati pa kutentha chitetezo chaLEDnyale.Ngati gwero lamphamvu lamphamvu la LED likutengera nyali za LED, mapiko ambiri a aluminiyamu radiator ayenera kutengedwa.Chifukwa cha malo ang'onoang'ono a nyali za LED zowunikira m'nyumba, vuto la kutaya kutentha likadali chimodzi mwazovuta zazikulu zamakono zamakono.

Kutentha kosakwanira kwa nyali za LED kungayambitse kulephera kwa kuwala koyambirira kwa gwero la kuwala kwa LED chifukwa cha kutentha kwambiri.Pambuyo poyatsa nyali ya LED, kutentha kudzawonjezedwa ku kapu ya nyali chifukwa cha kukwera kwa mpweya wotentha, zomwe zidzakhudza moyo wautumiki wa magetsi.Choncho, popanga nyali za LED, NTC ikhoza kukhala pafupi ndi radiator ya aluminiyamu pafupi ndi gwero la kuwala kwa LED kuti itenge kutentha kwa nyali mu nthawi yeniyeni.Pamene kutentha kwa radiator ya aluminiyamu ya kapu ya nyali kumawuka, derali lingagwiritsidwe ntchito kuti lichepetse kutulutsa kwamakono kwa gwero lokhazikika lamakono kuti aziziziritsa nyali;Kutentha kwa radiator ya aluminiyamu ya kapu ya nyali kukakwera kufika pamtengo wokhazikika, magetsi a LED amazimitsidwa kuti azindikire kutetezedwa kwa kutentha kwa nyali.Kutentha kukachepa, nyaliyo imayatsidwanso.

Sensa ya mawu

Sensa yowongolera mawu imapangidwa ndi sensa yowongolera mawu, amplifier ya audio, dera losankhira njira, kuchedwetsa kutsegulira dera ndi gawo lowongolera la thyristor.Yerekezerani ngati muyambe kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Sensa yowongolera phokoso nthawi zonse imafanizira mphamvu yakunja yakunja ndi mtengo wapachiyambi, ndipo imatumiza chizindikiro cha "phokoso" kumalo olamulira pamene ikupitirira mtengo woyambirira.Sensa yowongolera mawu imagwiritsidwa ntchito kwambiri m'makonde ndi malo owunikira anthu.

Microwave induction sensor

Microwave induction sensor ndi chojambulira chinthu chosuntha chopangidwa kutengera mfundo ya Doppler effect.Imazindikira ngati malo a chinthucho akuyenda mwanjira yosalumikizana, kenako imapanga ntchito yosinthira yofananira.Wina akalowa m'malo owunikira ndikufika pomwe pakufunika kuyatsa, cholumikizira chimangotseguka, chida chonyamula katundu chidzayamba kugwira ntchito, ndipo njira yochedwetsa idzayambika.Malingana ngati thupi la munthu silichoka pamalo omvera, chipangizo chonyamula katundu chidzapitiriza kugwira ntchito.Thupi la munthu likachoka pamalo ozindikira, sensa imayamba kuwerengera kuchedwa.Kumapeto kwa kuchedwa, chosinthira cha sensor chimangotseka ndipo chida chonyamula katundu chimasiya kugwira ntchito.Zotetezekadi, zosavuta, zanzeru komanso zopulumutsa mphamvu.
