Isixhumi ekuholeni singase sidinge ukusunduza okuqinile ukuze usifake kahle ku-SPS30.
I-SPS30 futhi isekela isixhumi esibonakalayo se-serial esituswa yi-Sensirion kudatha yedatha.
Okunye okufanele kucatshangelwe mayelana nokusetshenziswa kwesixhumi esibonakalayo se-I2C. I-I2C ekuqaleni yayiklanyelwe ukuxhuma ama-chips amabili ku-PCB. Uma inzwa ixhunywe ku-PCB eyinhloko ngekhebula, ukunakwa okukhethekile kufanele kukhokhwe ekuphazamiseni kazibuthe kagesi kanye ne-crosstalk. Sebenzisa ngokumfushane ngangokunokwenzeka (< 10 cm) kanye/noma izintambo zokuxhuma ezivikelwe kahle.
Sincoma ukuthi usebenzise isixhumi esibonakalayo se-UART esikhundleni salokho, noma nini lapho kungenzeka: iqine kakhulu ngokumelene nokuphazamiseka kazibuthe kagesi, ikakhulukazi ngezintambo ezinde zokuxhuma.
Kukhona futhi isexwayiso mayelana nezingxenye zensimbi zecala.
Qaphela, ukuthi kunokuxhumana kukagesi kwangaphakathi phakathi kwephinikhodi ye-GND (5) nesivikelo sensimbi. Gcina lesi sivikelo sensimbi sisebenza ngogesi ukuze ugweme noma yikuphi ukugeleza okungahlosiwe ngalokhu kuxhumana kwangaphakathi. Uma lokhu kungeyona inketho, ukulingana okunamandla kwangaphandle okufanelekile phakathi kwephinikhodi ye-GND nanoma yimaphi amandla axhunywe kusivikelo kuyisibopho. Noma ikuphi okwamanje nakuba ukuxhumana phakathi kwe-GND nesivikelo sensimbi kungalimaza umkhiqizo futhi kudale ingcuphe yezokuphepha ngokushisa ngokweqile.

Isinyathelo sesi-6: Ukuxhuma i-Omron B5W LD0101

Ikhebula le-Omron ayihloselwe ukusetshenziswa nebhodi lezinkwa. Enye indlela esheshayo yokuyiguqulela ekusetshenzisweni kwe-breaboard ukusika isokhethi, ukukhumula izintambo futhi uzidayise kumaphini amahlanu ubude bezikhonkwane zekhanda wesilisa. Iziqeshana zengwenya (alligator) zingasetshenziswa njengenye indlela yokugwema ukusoda.
I-Omron B5W LD0101 idinga ukunikezwa kwamandla okungaguquki okungu-5V. Imiphumela yayo emibili iphinde ibe sezingeni elingu-5V elingahambisani nokufaka kwePi Pico engu-3.3V. Ukuba khona kwama-resistor ebhodini lezinzwa kwenza kube lula ukuphonsa lokhu kunani eliphephile ngokungeza i-resistor engu-4.7k emhlabathini okukhiphayo ngakunye. Ama-resistors asebhodini abhalwe kudathabhethi okwenza lokhu kube indlela enengqondo.
Ukuxhumana okusuka ku-B5W LD0101 kuya ku-Pi Pico yilokhu:

• Vcc (obomvu) kuya ku-5V (obomvu) ujantshi ngomugqa wama-25;

Izinto ezingcolisayo zizohluka kakhulu kunalezo eziphuma ku-reworks. Lesi yi-ex ethokozisayoample yemithombo eyahlukene yezinhlayiyana ezisemoyeni esiwuphefumulayo.

Isinyathelo se-14: Izinzwa Eziyingxenye Yomphakathi

Idatha efakwe ngenhla isuka kuzinzwa zomphakathi eziseduze.

• Adonse umoya eLondon
  • I-Clarity Movement Node-S
    • tbps
    • oss
    • rl
• I-OpenAQ
  • I-PurpleAir PA-II
    • sr
• London Air Quality Network
  • Ikhwalithi yereferensi (Met One BAM 1020 nezinye)
    • FS
    • AS
    • I-TBR

Izinzwa ze-tbps ne-TBR cishe zibekwe ndawonye futhi zifakwe igrafu ndawonye ukuze zibonise ukuhlobana phakathi kwedivayisi esekelwe ku-SPS30 kanye nesithenjwa esiseduze. I-SPS30 ibonakala ifundeka kancane ngokuzwakalayo kusihlwa ngomhla ka-5 no-6 Novemba lapho kunengqondo ukucabanga ukuthi ukunyuka kwakusihlwa kungenxa yokuphinda kusetshenzwe kabusha. Lokhu kungase kube ngenxa yomehluko wesisindo sezinhlayiya njengoba izinzwa ezisetshenziselwa lesi sihloko zingakwazi ukubona ivolumu kuphela futhi zidinga ukuqagela ukuminyana kwezinhlayiya ukuze zikhiqize amanani ngama-micrograms per cubic meter ngayinye.
I-PMS5003 ku-PurpleAir PA-II ibonakala ifundeka ngokweqile ngokuphawulekayo kunoma imaphi amazinga aphakanyisiwe we-PM2.5 asekelwe kulesi sikhathi esifushane. Lokhu kungase kufane nemiphumela eboniswe emakhasini adlule noma kungase kube nezinye izici eziseduze ezibangela lokhu.
I-SPS30 ne-PMS5003 zikhiqiza idatha yezinhlayiya ezinkulu kuno-2.5 ​​microns kodwa amakhasi alandelayo abonisa ukuthi kungani lokhu kufanele kuphathwe ngokuqapha.

Isinyathelo 15: Ukuqhathaniswa Kwezinzwa - Usayizi Wezinhlayiyana

Amagrafu angenhla asuka ekuhlolweni Kwaselabhorethri kokukhetha usayizi wezinhlayiyana wezinzwa ze-optical ezibiza izindleko eziphansi ze-particulate matter yi-Finnish Meteorological Institute. Izinzwa ezintathu zohlobo ngalunye zihlolwe ngosayizi abahlukene bezinhlayiyana eziboniswe ku-axis ye-logarithmic x. Imigqa enombala ikhombisa amanani abaliwe amabhendi osayizi wezinhlayiyana ezithile ngokusekelwe kokuphumayo kwenzwa, ibhande libonisa ukusatshalaliswa. Amanani amathathu e-SPS30 ngaphezulu kwe-micron engu-1 agqagqana kakhulu okwenza kube nzima kakhulu ukuhlukanisa.
Amamethrikhi ajwayelekile ezinhlayiya yi-PM2.5 kanye ne-PM10. Ngenkathi inombolo esegameni isho ubukhulu bobukhulu bezinhlayiyana amayunithi aku-micrograms per cubic meter. Izinzwa ezishibhile zingakala kuphela ububanzi bezinhlayiyana (ivolumu) futhi kufanele zenze ukuqagela mayelana nokuminyana ukuze zibale amanani okungenzeka ukuthi angu-PM2.5 kanye ne-PM10.
I-PMS5003 isebenzisa inani elingaguquki lokuminyana, i-Sensirion ichaza indlela yabo yokuminyana ye-SPS30 ngokuthi:
Izinzwa eziningi ze-PM ezibiza kancane emakethe zithatha ukuminyana okungaguquki kwesisindo ekulinganisweni futhi zibale ukugxiliswa kwesisindo ngokuphindaphinda isibalo sezinhlayiyana ezitholiwe ngalobu bunzima. Lokhu kucabangela kusebenza kuphela uma inzwa ikala uhlobo olulodwa lwezinhlayiya (isibonelo, intuthu kagwayi), kodwa empeleni sinezinhlobo eziningi zezinhlayiya ezinezici eziningi ezihlukene zokubona ekuphileni kwansuku zonke, kusukela othulini lwasendlini 'olusindayo' kuya ezinhlayiyeni zomlilo 'ezikhanyayo'. . Ama-algorithms obunikazi be-Sensirion asebenzisa indlela ethuthukisiwe evumela ukulinganisa okufanele kokugxila okukhulu, kungakhathaliseki uhlobo lwezinhlayiyana olulinganiswayo. Ngaphezu kwalokho, indlela enjalo yenza ukulinganisa okulungile kwemigqomo yosayizi.
Amamethrikhi e-PM ahlanganisa zonke izinhlayiya ezingaphansi kwepharamitha kasayizi, isb
PM1 + isisindo sazo zonke izinhlayiya eziphakathi kuka-1.0 no-2.5 ​​microns = PM2.5,
PM2.5 + isisindo sazo zonke izinhlayiya phakathi kwama-microns angu-2.5 no-10 = PM10.
I-PMS5003 ne-SPS30 azikwazi ukubona izinhlayiya zalolu hlolo lwaselabhorethri ezingaphezu kwama-microns angu-2-3. Kungenzeka ukuthi bangathola ezinye izinhlobo zezinhlayiya ezingaphezu kwalo sayizi.
I-B5W LD0101 ibukeka ithembekile kulokhu kuhlolwa kwaselabhorethri ukuze kukale i-PM10.

Isinyathelo 16: Ukuqhathaniswa Kwezinzwa - Idizayini

I-heater ye-Omron (i-100 ohm +/- 2% resistor!) ingabonakala uma inzwa ibhekiswe phansi. Umklamo uxoxwa ngokuningiliziwe ku-Omron: Ukuthuthukiswa kwenzwa yekhwalithi yomoya ye-air purffer. Ukusetshenziswa kwe-convection kubonakala kungenangqondo kodwa kungaba yisixazululo esinokwethenjelwa okuphezulu uma kuqhathaniswa nengxenye yomshini efana nesiphephetha-moya esinesikhathi sokuphila se-nite kanye nempilo yonke engancishiswa ngokusebenza endaweni enothuli. I-SPS30 fan ibonakala iklanyelwe ukushintshwa kalula ngaphandle kokuvula ikesi. Amanye amamodeli we-Plantower anesici sokuklama esifanayo.
Zontathu izinzwa zizothambekela emiphumeleni yokuswakama okuphezulu okuhlobene okukhuphula ngephutha amanani e-PM.
Izinzwa eziqinisekisiwe, zekhwalithi yereferensi (uhlu lwe-DEFRA yase-UK) eziqapha i-particle ayisebenzisi indlela yokubona ukuze ikale. I-Met One BAM 1020 isebenza nge

1. ukuhlukanisa nokulahla izinhlayiya ezinkulu kunomkhawulo wosayizi osuka emoyeni sample,
2. ukushisa umoya ukulawula/ukunciphisa umswakama ohlobene,
3. ukufaka izinhlayiya engxenyeni entsha ye-tape ye-brous eqhubekayo futhi
4. bese ukala ukuncishiswa komthombo wemisebe ye-beta ngezinhlayiya eziqoqiwe ku-tape ukubala isilinganiso esihle sengqikithi yesisindo sezinhlayiya.

Enye indlela evamile i-Tapered Element Oscillating Microbalance (TEOM) efaka izinhlayiya endaweni eshintshwayo ekugcineni kweshubhu elicijile elixhunywe ngakolunye uhlangothi. Ukulinganisa okunembile kwe-oscillation frequency yeshubhu elizwakalayo ngokwemvelo livumela isisindo esincane esengeziwe sezinhlayiya ukuba sibalwe kusukela ekuhlukeni kwe-miniscule in frequency. Le ndlela ifanele ukudala amanani aphezulu e-PM.
