Eyona sixhobo sokucoca umoya silungileyo seso sisebenza ngokuchanekileyo xa kufuneka - kwaye isenzi se-PM2.5 esidibeneyo senza oko kube nokwenzeka.
Isicoci somoya senzwa ye-PM2.5 sisebenzisa isixhobo sokubona izinto ezincinci esakhelwe ngaphakathi ukuze siqhubeke nokujonga uxinano lweziqwenga ezincinci emoyeni ongqongileyo. Xa amanqanaba ongcoliseko enyuka, esi sixhobo sibangela uhlengahlengiso oluzenzekelayo — sinyusa isantya sefeni, sisebenzise amanqanaba athile okuhluza, kwaye sibonise impendulo yomgangatho womoya ngexesha langempela. Xa umoya ucocekile, iyunithi iyacotha ngokuzenzekelayo okanye ingene ngexesha lokulinda, igcina amandla kwaye yandise ubomi besihluzo.
Kubathengi be-B2B, ukuhlanganiswa kwe-PM2.5 sensor kuye kwatshintsha ukusuka kwisici se-premium ukuya kwisiseko esilindelekileyo kwizicoci zomoya zabathengi kuzo zonke iindawo zemarike. Eli nqaku ligubungela indlela ezisebenza ngayo izicoci ze-PM2.5, iinkcukacha eziphambili zokufumana i-OEM, kunye nendlela ukufunyanwa okukrelekrele okudala ngayo ixabiso lokwenyani kubasebenzisi bokugqibela.
Indlela ezisebenza ngayo iiSensors ze-PM2.5 kwi-Air Purifiers
Itekhnoloji yokusasaza ngeLaser
Uninzi lwezixhobo zokucoca umoya zanamhlanje zisebenzisa izinzwa zesuntswana ezisekelwe kwilaser. Ifeni encinci itsala umoya kwigumbi lokufumanisa apho i-laser diode ikhanyisa naziphi na iisuntswana ezikhoyo. Xa iisuntswana zidlula kwi-laser beam, zisasaza ukukhanya. I-photodetector ilinganisa ubunzulu bokukhanya okusasazekileyo — iisuntswana ezininzi = ukukhanya okungakumbi = ukufundwa okuphezulu kwe-PM. I-microcontroller yesi senzwa ihlalutya iipatheni ukuze yahlule ubungakanani be-PM1.0, PM2.5, kunye ne-PM10, ibonelela ngokufundwa okuphantse kube ngoko nangoko rhoqo emva kwemizuzwana eli-1-5.
Izixhobo zeSensor ezibalulekileyo
• I-laser diode (ibomvu eyi-650nm okanye i-905nm IR) — inika ukukhanya
• I-PIN photodiode — ilinganisa ukukhanya okusasazekileyo; uvakalelo lumisela ubungakanani obuncinci beesuntswana ezinokubonwa
• I-Signal MCU — iguqula imiqondiso eluhlaza ibe ngamanani amasuntswana; ukulinganisa kulungisa ukufuma kunye nokwaluphala
• Ukungenisa umoya (i-micro-fan) — kutsala isampuli efanayo; ukuzinza kokuhamba kwamanzi kuchaphazela ukuchaneka
• Ukulinganiswa kwefektri — ngokuchasene nesixhobo sokubhekisa; izinzwa ezilinganiswe kakuhle zifezekisa impazamo engaphantsi kwe-±10 µg/m³
Iimpawu zokuchonga ezikrelekrele ezidala ixabiso lokwenyani lomsebenzisi
Imo Ezenzekelayo: Uhlengahlengiso lwesantya seFeni oluzenzekelayo
Xa i-sensor ye-PM2.5 ibona ungcoliseko olukhulayo, i-purifier inyusa ngokuzenzekelayo ukuhamba komoya. Njengoko umoya uphuma, inciphisa isantya. Iiparameter eziphambili kubathengi be-B2B: isantya sempendulo (esijoliswe kuyo <10 sec), amanqanaba omyinge (amanyathelo esantya ama-4-6), kunye ne-hysteresis (ithintela ukushukuma okujikeleze umda).
Umboniso woMgangatho woMoya weXesha langempela
• I-LED enemibala: Luhlaza (<35 µg/m³) → Mthubi (35-75) → Bomvu (>75) ngokuhambelana nemigangatho yombala ye-EPA/AQI
• Isiboniso se-PM2.5 samanani kwi-µg/m³; ezinye iimodeli zikwabonisa i-PM10, ubushushu, kunye nokufuma
• Ukuvumelanisa ii-app ze-WiFi/BLE ngeqonga leTuya Smart ledatha yembali kunye nolawulo olukude
Hlunga ukuLandelela ubomi bonke
Izinzwa eziphambili zilandelela ukugcwala kwesihluzo ngokujonga ukuba ukufunda kusabela ngokukhawuleza kangakanani kutshintsho lwesantya sefeni. Isihluzo esicocekileyo sibonisa ukuhla okukhawulezayo kwe-PM2.5 xa isantya sefeni sisanda; isihluzo esigcweleyo sibonisa utshintsho oluncinci. Oku kwenza ukuba kuqikelelwe ubomi besihluzo ngaphandle kwezinto ezahlukeneyo zexesha.

Iisensa ze-PMS5003-series (Plantower) zezona zisemgangathweni zifanelekileyo kwizicoci zabathengi, zibonelela ngexabiso elifanelekileyo lokusebenza. I-Honeywell kunye ne-Sensirion zibonelela ngeendlela ezichanekileyo kakhulu kwiilayini zeprimiyamu.
Ukubekwa kweSensor: Kutheni Indawo Ibaluleke Ngaphezulu KweSensor
Eyona sensor ichanekileyo inika ukufundwa okulahlekisayo ukuba ibekwe ngendlela engafanelekanga. Izinto ezimbini ezibalulekileyo ekufuneka ziqwalaselwe:
• Ukungenisa umoya xa kuthelekiswa nokukhupha umoya: Inzwa ekwindlela yokungenisa umoya ifunda umoya wegumbi (ichanekile). Inzwa emva kwe-HEPA ifunda umoya ococekileyo (uphantsi ngokungeyonyani). Uyilo lwe-dual-sensor lulinganisa zombini ukuqinisekisa ukusebenza kakuhle.
• Indlela yokudlula komoya: I-sensor ifuna isampulu yomoya ehambelanayo. Ziphephe iindawo ezifileyo ngasemva kwee-baffles. Qinisekisa ukuba i-micro-fan ye-sensor itsala isampuli entsha ngaphandle komoya ophambili.
Indlela Ukuchonga Okukrelekrele Okudala Ngayo Iingenelo Ezibonakalayo Zomsebenzisi
✓ Ukonga amandla: Imo ye-Auto inciphisa isantya sefeni esiqhelekileyo ngama-40-60%, inciphisa iindleko zombane malunga nama-50%
✓ Ulwandiso lobomi bokucoca: Ifeni isebenza kuphela xa kufuneka, yandisa izithuba zeHEPA/carbon
✓ Ukunciphisa ingxolo: Isantya esiphezulu kuphela xa kufuneka. Ukusebenza ebusuku kwi ~20-30 dB phantse kuthule
✓ Uxolo lwengqondo: Isibonisi se-AQI sexesha langempela sinika ubungqina obubonakalayo bokuba isicoci siyasebenza — umqhubi ophezulu wolwaneliseko
✓ Ukubeka esweni kude: Abasebenzisi abaqhagamshelwe kwi-WiFi bajonga umoya wasekhaya naphi na; baqhuba injongo ebalulekileyo yokuthenga
Imida kunye nokuqwalaselwa koyilo
✗ Akukho kubhaqwa kwe-VOC/igesi: Izinzwa eziqhelekileyo ze-PM2.5 azibhaqi i-formaldehyde, ii-VOC, okanye i-CO2. Kufuneka izinzwa zegesi ezahlukeneyo.
✗ Ukuphazamiseka komswakama: >85% i-RH ibangela ukudumba kwamasuntswana kunye nokufundwa okuphezulu okungachanekanga. Ezinye izinzwa ziquka ukubuyiselwa komswakama.
✗ Ukujika komlinganiselo: Kwiminyaka engaphezu kwemi-2-3, amandla elaser ayawohloka kwaye ii-optics ziqokelela ungcoliseko. Ukutshintshwa yinto eqhelekileyo.
✗ Izinto ezibangela ubushushu obungachanekanga: Izinto ezifumisayo okanye umphunga wokupheka zinokubangela ukufundwa kwe-PM okungachanekanga. Ezinye iiyunithi zisebenza emva kwemizuzwana engama-30 ukuya kwengama-60 emva kokuba ubushushu bunyuke kakhulu.
Isiphelo: Ukuchonga okuKhawulezayo njengeMfuneko yoKhuphiswano
Ukuhlanganiswa kwe-PM2.5 sensor kuye kwatshintsha ukusuka kwi-differentiator ukuya kwi-baseline expectation. Ngo-2026, umbuzo awusekho kukuba kufuneka kufakwe i-sensor na — kukuba yeyiphi i-sensor kwaye inkqubo isebenzisa idatha ngobuchule kangakanani.
1. Izinzwa ze-PM2.5 ezisekelwe kwi-laser (iklasi ye-PMS5003) zibonelela ngokusebenza okuthembekileyo ngexabiso le-OEM le-$3-8, kwaye ziyasebenza nakwiimveliso ezikumgangatho wokuqala.
2. Imo ye-Auto ene-real-time AQI display yeyona nto ifanelekileyo. I-WiFi/IoT lelona nqanaba lilandelayo
3. Ukubekwa kwesensor kunye noyilo lokuhamba komoya kuchaphazela ukuchaneka ngaphezu kwemodyuli yesensor ngokwayo
4. Ukulandelela ukutshintshwa kwesihluzo ngedatha yesenzi kwandisa ubomi besihluzo ngama-20-30% kwaye kuphucula iindleko zizonke zobunini
5. Izicoci ze-Smart PM2.5 zibiza i-25-40% ephezulu ngokuthengisa kuneeyunithi zesantya esiqhelekileyo sesandla
