Hauv kab ntawv no, peb yuav kawm paub tsim qhov yooj yim tab sis muaj txiaj ntsig huab cua zoo li cas. Peb yuav siv lub SGP30 sensor nrog rau Piksey Pico, txawm hais tias daim duab kos yuav ua haujlwm nrog ntau yam zoo ib yam Arduino pawg thawj coj saib.

Cov vis dis aus saum toj no tham koj los ntawm qhov tseem ceeb ntawm qhov ntsuas. Peb kuj tham txog ntau yam uas tau txiav txim siab thaum xaiv cov khoom siv rau txoj haujlwm no. Kuv pom zoo saib nws kom tau txais kev txheeb xyuas txhua yam, tshwj xeeb yog tias koj yuav siv PCB uas tau tsim los rau txoj haujlwm no.

Kauj Ruam 1: Sau Cov Khoom Siv Hluav Taws Xob

Koj yuav xav tau cov hauv qab no txhawm rau tsim txoj haujlwm no:

• SGP30 sensor: qhov no tuaj yeem tau online los ntawm cov chaw xws li Pimoroni, Adafruit, Sparkfun
• OLED module: Tus qauv 0.96 "OLED module yuav ua haujlwm zoo
• Arduino pawg thawj coj: Kuv yuav siv Piksey Pico tab sis koj tuaj yeem siv ib qho Arduino board uas koj muaj
• Qib shifter: Peb tsim 5V txog 3.3V qib hloov pauv rau OLED module, tab sis koj tseem tuaj yeem yuav ib qho
• 3.3V qhov ntsuas hluav taws xob: Peb siv LM2950 qhov ntsuas hluav taws xob los tsim 3.3V lub zog hluav taws xob xav tau los ntawm OLED module

Kauj ruam 2: Rub lub Sketch & Program Board

Koj tuaj yeem rub tawm qhov kos duab kawg siv qhov txuas hauv qab no:

github.com/bnbe-club/air-quality-sensor-kit-diy-19

Ua ntej koj tuaj yeem sau thiab xa cov duab kos, koj yuav tsum teeb tsa "Sparkfun SGP30" thiab "U8g2" cov tsev qiv ntawv siv tus thawj tswj tsev qiv ntawv. Thov saib cov vis dis aus yog tias koj xav tau kev pab nrog qhov no.

Thaum ua tiav, tsuas yog rub cov duab kos rau koj lub rooj tsavxwm.

Kauj Ruam 3: Conenct Cheeb Tsam & Cov Qauv

Tom qab ntawd peb yuav tsum txuas tag nrho cov khoom ua ke. Yog tias koj siv PCB, koj tsuas yog yuav tsum tau muab cov khoom sib dhos tso rau hauv qhov chaw. Daim vis dis aus qhia koj yuav ua li cas.

Koj tseem tuaj yeem siv daim ntawv qhia zaub mov nrog rau daim duab txuas rau kom txhua yam ua ke. LM2950 yog 3.3V tus tswj hwm uas xav tau tsuas yog koj li OLED module tsis muaj tus tswj hwm ua haujlwm thiab xav tau 3.3V rau kev ua haujlwm. Qee cov qauv OLED ua haujlwm nrog 5V muab khoom thiab hauv qhov xwm txheej ntawd, koj yuav tsis xav tau ntu no.

Kauj Ruam 4: Kuaj & Saib Xyuas Huab Cua Zoo

Thaum koj muaj txhua yam wired hauv qhov chaw. Lub zog me me ntawm kev tsim siv lub microUSB cable thiab koj yuav tsum pom cov zis ntawm OLED module. Nco ntsoov tias thawj 15 CO2 nyeem yuav yog 400ppm, uas TVOC nyeem yuav yog 0ppb raws li cov cua sov sab hauv yuav tsum tau sov.

Koj kuj tseem tuaj yeem hloov kho qhov no txhawm rau ntxiv lub suab nrov ceeb toom rau koj yog tias qib hla mus rau qee qhov pib. Kev tsim PCB tau tshaj tawm ntawm Github thiab koj tuaj yeem siv qhov ntawd los xaj koj li PCBs. Kuv xaj qee qhov PCBs ntxiv thiab kuv tau teev cov no muag rau ntawm lub vev xaib yog tias koj tab tom nrhiav rau qee qhov.

Yog tias koj nyiam txoj haujlwm no, tom qab ntawv thov txiav txim siab tso npe rau peb YouTube channel vim nws pab peb loj hlob.
