Sesebelisoa sena se bokella boitsebiso bo mabapi le mocheso ho tsoa mohloling ebe se o fetola ka mokhoa o ka utloisisoang ke lisebelisoa tse ling kapa batho.Mohlala o motle ka ho fetisisa oa sensor ea mocheso ke khalase ea mercury thermometer, e atolohang le ho etsa likonteraka ha mocheso o fetoha.Mocheso o ka ntle ke mohloli oa tekanyo ea mocheso, 'me motho ea shebileng o sheba boemo ba mercury ho lekanya mocheso.Ho na le mefuta e 'meli ea motheo ea li-sensor tsa mocheso:
· Ikopanye le sensor
Sensor ea mofuta ona e hloka hore motho a kopane ka kotloloho le ntho e utloiloeng kapa e bohareng.Ba khona ho hlokomela mocheso oa lintho tse tiileng, metsi le likhase ho feta mocheso o pharaletseng.
· Sensor e sa amaneng le batho
Sensor ea mofuta ona ha e hloke hore motho a kopane le ntho kapa sehare se bonoang.Li beha leihlo lintho tse tiileng le lintho tse metsi tse sa boneng, empa ha li na thuso khahlano le likhase ka lebaka la ponahalo ea tsona ea tlhaho.Lisensara tsena li lekanya mocheso ka molao oa Planck.Molao o sebetsana le mocheso o tsoang mohloling oa mocheso ho lekanya mocheso.
Melao-motheo ea ho sebetsa le mehlala ea mefuta e fapaneng ealisensara tsa mocheso:
(i) Thermocouples - Li na le lithapo tse peli (e 'ngoe le e' ngoe ea motsoako o fapaneng oa li-uniform kapa tšepe) e etsang motsoako oa ho lekanya ka ho hokahanya pheletsong e 'ngoe e bulehileng ho element tlas'a teko.Karolo e 'ngoe ea terata e hokahane le sesebelisoa sa ho lekanya, moo ho thehoang mateano a litšupiso.Kaha mocheso oa li-node tse peli o fapane, hona joale o phalla ho potoloha 'me li-millivolts tse hlahisoang li lekanyetsoa ho fumana mocheso oa node.
(ii) Resistance Temperature Detectors (RTDS) - Tsena ke li-resistance thermal resistors tse etselitsoeng ho fetola ho hanyetsa ha mocheso o fetoha, 'me li theko e boima ho feta lisebelisoa leha e le life tsa ho lemoha mocheso.
(iii)Thermitors- ke mofuta o mong oa ho hanyetsa moo liphetoho tse kholo tsa ho hanyetsa li lekanyelitsoeng kapa tse fapaneng le liphetoho tse nyenyane tsa mocheso.
(2) Sensor ea infrared
Sesebelisoa se ntša kapa se lemoha mahlaseli a infrared ho utloa mekhahlelo e itseng tikolohong.Ka kakaretso, mahlaseli a chesang a hlahisoa ke lintho tsohle tse ka har'a mahlaseli a infrared, 'me li-sensor tsa infrared li lemoha mahlaseli ana a sa bonahaleng mahlong a motho.
· Melemo
Ho bonolo ho hokahanya, ho fumaneha 'marakeng.
· Mefokolo
Ho ferekanngoa ke lerata la ambient, joalo ka mahlaseli, khanya ea ambient, joalo-joalo.
Kamoo e sebetsang kateng:
Taba ea mantlha ke ho sebelisa li-diode tse ntšang khanya ea infrared ho hlahisa leseli la infrared linthong.E 'ngoe ea infrared diode ea mofuta o tšoanang e tla sebelisoa ho bona maqhubu a bonahatsoang ke lintho.
Ha moamoheli oa infrared a khantšitsoe ke leseli la infrared, ho na le phapang ea voltage terateng.Kaha motlakase o hlahisoang o le monyenyane ebile ho thata ho o lemoha, amplifier ea ts'ebetso (op amp) e sebelisoa ho lemoha ka nepo maqhubu a tlaase.
(3) Sensor ea ultraviolet
Lisensara tsena li lekanya botebo kapa matla a ketsahalo ea lebone la ultraviolet.Mahlaseli ana a motlakase a na le bolelele bo bolelele ho feta X-ray, empa a ntse a le makhutšoanyane ho feta khanya e bonahalang.Ntho e sebetsang e bitsoang polycrystalline diamond e sebelisoa bakeng sa ho lemoha mahlaseli a kotsi, a ka bonang ho pepeseha ha tikoloho mahlaseling a kotsi.
Litekanyetso tsa ho khetha li-sensor tsa UV
* Leqhubu la bolelele bo ka bonoang ke sensor ea UV (nanometer)
· Mocheso oa ho sebetsa
· Ho nepahala
· Boima ba 'mele
· Lethathamo la matla
Kamoo e sebetsang kateng:
Li-sensor tsa Uv li amohela mofuta o le mong oa lets'oao la matla ebe li fetisetsa mofuta o fapaneng oa lets'oao la matla.
E le ho shebella le ho rekota lipontšo tsena tsa tlhahiso, li lebisitsoe ho meter ea motlakase.Ho hlahisa lits'oants'o le litlaleho, lets'oao la tlhahiso le fetisetsoa ho converter ea analog-to-digital (ADC) ebe ho komporo ka software.

· Lekanya karolo ea mahlaseli a mahlaseli a kotsi a letsatsi a chesang letlalo
· Pharmacy
· Likoloi
· Liroboto
· Kalafo le mokhoa oa ho daea bakeng sa indasteri ea khatiso le ho daea
Indasteri ea lik'hemik'hale bakeng sa tlhahiso, ho boloka le ho tsamaisa lik'hemik'hale
(4) Sensor ea ho ama
Sensor ea ho ama e sebetsa joalo ka mohanyetsi o fapaneng ho latela boemo ba ho ama.Setšoantšo sa sensor ea ho ama e sebetsang e le mohanyetsi o fapaneng.
The touch sensor e na le likarolo tse latelang:
· Lintho tse tsamaisang ka ho feletseng, tse kang koporo
• Lisebelisoa tsa ho sireletsa spacer, joalo ka foam kapa polasetiki
· Karolo ea thepa ea conductive
Molao-motheo le mosebetsi:
Lisebelisoa tse ling tsa conductive li hanyetsa ho phalla ha hona joale.Molao-motheo o ka sehloohong oa li-sensor tsa boemo bo holimo ke hore ha nako e telele e le bolelele ba thepa eo hona joale e lokelang ho feta ho eona, ho feta moo phallo ea hona joale e fetohang.Ka lebaka leo, ho hanyetsa ha thepa ho fetoha ka ho fetola boemo ba eona ba ho kopana le thepa e tsamaisang ka ho feletseng.
Ka tloaelo, software e hokahane le sensor ea ho ama.Tabeng ena, memori e fanoa ke software.Ha li-sensor li tingoa, li khona ho hopola "sebaka sa ho qetela".Hang ha sensor e se e sebetsa, ba ka hopola "sebaka sa pele sa ho ikopanya" le ho utloisisa litekanyetso tsohle tse amanang le eona.Ketso ena e ts'oana le ho tsamaisa mouse le ho e beha ka lehlakoreng le leng la "mouse pad" e le ho isa sesupa pheletsong e hole ea skrini.
Etsa kopo
Li-sensors tsa ho ama li na le chelete e ngata ebile lia tšoarella, 'me li sebelisoa haholo

Li-sensor tsa proximity li lemoha boteng ba lintho tse se nang libaka tsa ho ikopanya.Hobane ha ho na puisano pakeng tsa sensor le ntho e lekantsoeng, 'me ka lebaka la ho haella ha likarolo tsa mechine, li-sensor tsena li na le bophelo bo bolelele ba tšebeletso le ho tšepahala ho phahameng.Mefuta e fapaneng ea li-proximity sensors ke inductive proximity sensors, capacitive proximity sensors, ultrasonic proximity sensors, photoelectric sensors, Hall effect sensors joalo-joalo.
Kamoo e sebetsang kateng:
Sensor ea proximity e hlahisa lebala la motlakase kapa motlakase kapa khanya ea mahlaseli a motlakase (joalo ka infrared) ebe e emela lets'oao la ho khutla kapa phetoho tšimong, 'me ntho e utloiloeng e bitsoa target ea "proximity sensor".
Li-sensor tsa inductive proximity - li na le oscillator e le ho kenya letsoho ho fetolang ho hanyetsa tahlehelo ka ho atamela mokhoa oa ho tsamaisa.Li-sensor tsena ke tsona tse ratoang ke tšepe.
Li-capacitive proximity sensors - li fetola liphetoho tsa matla a electrostatic mahlakoreng ka bobeli a electrode ea ho lemoha le electrode e thehiloeng.Sena se etsahala ka ho atamela lintho tse haufi le phetoho ea maqhubu a oscillation.Ho bona liphofu tse haufi, maqhubu a oscillation a fetoloa ho voltage ea DC mme a bapisoa le moeli o reriloeng esale pele.Li-sensor tsena ke khetho ea pele bakeng sa liphofu tsa polasetiki.
