Thaum ua haujlwm nrog cov phiaj xwm ua ntej ntawm kev ntsuas PM2.5 Kuv pom qhov tsis zoo ntawm qhov tsis tuaj yeem nrhiav cov ntsiab lus ntawm cov pa phem me me. Kev piv txwv feem ntau ua los ntawm cov nroog thiab cov duab satellite tau sau cov peev txheej dav uas tsis tau qhia koj tiag tiag ntawm tus kheej theem qhov twg los ntawm no thiab yuav tshem nws li cas. Cov cuab yeej Honeywell muaj nws tus kheej lub tshuab cua tshuab thiab lub qhov rai tso tawm txhua qhov kuv xav tau yog txoj hauv kev xa cov pa tshwj xeeb rau cov cheeb tsam ntawd-thiab tau kawg kuv twb muaj 3D luam/tsim cov dev lub qhov ntswg kom tso rau qhov kawg yog li qhov seem yog tsuas yog txhawm rau tsim chav ntsuas phom nrog qhov ua rau uas yuav ua rau kuv ua tib zoo tshawb nrhiav qhov twg kuv cov neeg tua neeg tuaj.

Tus hnoos hnoos tau tsim los kom lub tshuab ua pa hauv lub HoneyWell sensor tau ua raws thiab ntim rau hauv lub tsev ntawm cov hnoos qeev xws li lub qhov ntswg hauv qhov qhib kawg txuas ncaj qha nrog cov chaw nres nkoj nkag ntawm lub sensor thiab lub qhov tso tawm mus los ntawm lub tsev thiab tawm los ntawm ntau qhov hauv qab cowling. (Jeez suab zoo li daim ntawv thov patent….bad) Qhov muaj peev xwm ua tau zoo tso cai rau lub roj teeb muaj peev xwm loj thiab tas cov khoom siv hluav taws xob txuas mus. Qhov chaw nres nkoj them nqi tau ua raws hauv qab ntawm lub tsev tuav. Lub nplhaib Neopixel teeb pom kev nyob ib ncig ntawm lub qhov ntswg tau tsim los ci los ntawm rooj plaub nyob rau sab saud. Kev tsim kho tau ua tiav kom lub hauv paus ntawm lub tsev loj tau ua tiav hauv PLA meej thiab tom qab ntawd hloov mus rau Grey PLA rau tus tuav thiab thaum kawg tshem PLA rau lub hauv paus tuav kom pom cov xim ntawm lub teeb pom kev kom pom. Lub tshuab ua haujlwm tau teeb tsa nrog lub pob khawm ua haujlwm uas tau luam tawm ua ib qho tab sis vam tias yuav txav mus dawb.

Txhua cov ntaub ntawv tau ua tiav nrog cov txheej txheem teeb tsa ntawm Cura rau ender 3. Tsis muaj kev txhawb nqa tau siv rau ib qho twg.

Daim duab kab hluav taws xob yog qhov tseem ceeb tib yam li kev thaiv rau: https://www.instructables.com/id/Bike-Analog-Pollution-Meter/ tshwj tsis yog tsis muaj servo thiab qhov tso tawm tau siv rau cov ntaub ntawv kab rau Neopixel nplhaib. Hauv qhov no lub zog khawm tswj lub zog los ntawm roj teeb mus rau lub zog txhawb nqa/them nyiaj nkaus xwb. Kab 5 volt los ntawm tus neeg txhawb zog yog tswj los ntawm qhov txwv hloov hauv tus tes tuav uas ua haujlwm zoo li lub tswb. Nws txuas lub zog los ntawm kev txhawb zog rau ob qho tib si Sensor, ESP32 thiab Neopixels ua rau lawv ib txhij. I2C npo tau tawm ntawm 3 volts los ntawm ESP32. Feem ntau ntawm cov xov hlau yuav tsum tau ua tiav thaum lub tes tuav tab tom tsim kho hauv ntu tom ntej vim tias koj yuav tsum pub cov xov hlau los ntawm ntau qhov qhib. Nco ntsoov koj ua khob cij ua ntej!

Lub nplhaib Neopixel tau xub muab tso rau hauv lub qhov ntswg kom ntseeg tau tias nws nyob tiaj tus thiab tsis cuam tshuam nws txoj kev sib txuas nruj rau lub cev tseem ceeb. Ua peb txoj kab xaim hla lub chaw nres nkoj sab ntawm lub cev tseem ceeb thiab nqes mus rau hauv tus tes tuav. Neopixels yuav tsum taw tes rau hauv lub tsev tseem ceeb. Tom qab ntawd Air Sensor tau muab tso rau hauv nws lub tsev nrog ntau qhov me me nkag mus rau lub qhov ntswg qhib thiab lub kiv cua tseem ceeb tig rov qab mus rau cov xov hlau tso tawm. Pub cov xov hlau tawm sab nraub qaum thiab nqes mus rau hauv cov tub ntxhais tuav uas lawv yuav raug muab muag rau ESP32. I2C lub vijtsam tau txuas rau ntu ua ntej thiab nws cov xov hluav taws xob tawm mus los ntawm lub qhov qhib los ntawm tus tes tuav thiab txuas mus rau lub rooj tsavxwm tseem ceeb. Cov kev sib tw cowling yog tom qab ntawd muab tso rau ntawm qhov chaw hla lub vijtsam. Txhua cov kua nplaum feem ntau yog E6000 txawm hais tias superGlue LocTight tseem tuaj yeem siv tau. Lub hauv ntej lub qhov ntswg lub khob hliav qab kuj tau muab tso rau hauv qhov chaw. Qhov kev txwv txwv yog xaim rau hauv thiab lo rau hauv txoj haujlwm nrog rau lub hauv paus tseem ceeb hloov/hloov. Lub rooj tsav xwm ESP tseem ceeb tau teeb tsa thiab lub roj teeb 18650 tau teeb tsa. Lub rooj txhawb siab tau txuas nrog kom ruaj ntseg rau lub hauv paus phaj ntawm chav tsev kom ntseeg tau tias lub chaw nres nkoj them nqi tau ua tib zoo nrog qhib. Kua nplaum ntawm lub hauv paus phaj thaum txhua yam ua haujlwm raug. Lub ntsuas hluav taws xob tau txuas nrog hla qhov txwv hloov hlau bar hauv qhov zam uas nws yooj yim nyem nws hauv txoj haujlwm qis. Ceev faj kom tsis txhob muab kua nplaum rau hauv qhov txwv hloov pauv.

Kauj ruam 5: Program Nws

Lub software siv qhov chaw nres nkoj txuas rau kev xa cov ntaub ntawv los ntawm lub ntsuas. Nws yog ib qho teeb meem teeb meem nrog lub ntsuas cua no uas nws tsis siv I2C nrog cov tsev qiv ntawv los ua kom yooj yim dua. Hloov chaw ntawm servo raws li tso tawm ib yam li hauv lub tsheb kauj vab hnia tus ntsuas no siv SSD1306 tso tawm los ntawm I2C. Neopixel zaub tau tswj hwm los ntawm Adafruit Neopixel Library hauv qhov pom pom pom zoo uas tsuas yog ua pa 3 lub teeb xim sib txawv rau qib PM2.5 hauv lub qhov ntswg. Yog tias qib qis dua 25 nws ua rau xiav, ntsuab yog nruab nrab ntawm 25 thiab 80 thiab liab yog tias dhau 80. Cov qib ua ntej no tuaj yeem rov pib dua hauv qhov haujlwm. Lawv raug tswj raws li kev tso tawm hauv cov ntaub ntawv hais txog qhov ua haujlwm zoo nyob hauv qab ntawm qhov haujlwm. Fonts rau qhov tso tawm ntawm lub vijtsam thiab qhov loj me ntawm lub vijtsam kuj tseem tuaj yeem hloov tau. Lub Sensor siv sijhawm nyeem ib zaug ib pliag.

Yog li nyob hauv nruab nrab ntawm qhov kev cais no nws nyuaj me ntsis kom tawm ntau thiab siv cov cuab yeej no yog li kuv tau nyam ua yeeb yaj kiab YouTube ib ncig ntawm lub tsev kom pom tias nws nkag mus sab hauv tsis zoo li cas. (Feem ntau kuv yuav tawm ntawm qhov no mus rau cov neeg nyob ze ze tshaj plaws lub tsheb tso pa tawm lossis nqes ntawm cov kas fes ci - yog kuv paub koj ntswj nrog kuv lub ntsws ua haujlwm!) Nws tau txais kev nyeem ntawv tsis raug thiab tom qab ntawd maj mam dhau 5 vib nas this kom ruaj khov. Kev nyeem ntawv feem ntau sib raug zoo nrog National Sampler txog li 1/2 mais ntawm qhov thaiv. Qhov kev poob siab ib txwm ntawm cov khoom ci ci kuv tau tso rau hauv lub vev xaib rau koj. Lwm cov vis dis aus yog ua Granola --yow-nws xau 50 ppm rau ib teev tom qab tawm hauv qhov cub. Lub qhov ntswg zoo li yuav tuav tus qib siab ntxhiab rau ib ntus yog li koj tuaj yeem tshuab lawv tawm kom nyeem lwm qhov tam sim. Ob lub hlis dhau los PPM2.5 yog qhov kev txhawj xeeb loj tam sim no tsis muaj leej twg nco txog nws. Kev sov thoob ntiaj teb-uas yog kev txhawj xeeb ntau dhau los.
