Cov Lus Qhia no piav qhia yuav siv lub ntsuas roj nrog koj li Arduino li cas. Qhov no cia koj Arduino tsis hnov tsw (thiab vim li no koj cov lus teb rau) tag nrho cov pa roj rau ntau yam nasties, suav nrog ethanol, methane, formaldehyde, thiab ib pawg ntawm lwm cov organic sib txuas tsis haum. Kuv tus nqi los ua qhov cuab yeej no tau qis dua $ 100, suav nrog tag nrho cov khoom siv Arduino. Nov yog daim video:. Thiab tsis yog, Kuv yuav tsis tso lub tsho rau:-) Kuv tau txais cov khoom siv / ua tiav cov ntawv no thiab qee qhov lwm yam haujlwm muag @ kuv lub vev xaib -a lab saib xyuas: $ 295-ib qho khoom siv ntsuas ib qho rau cov khoom sib txuas uas tsis hloov pauv: $ 234 Kuv tau kawm txog qhov no tom qab hnov txog qee tus hais mav uas ntxiv VOC cov cim rau cov khoom ua si dev. Tsis paub meej qhov twg/yog tias cov ntaub ntawv ntawm txoj haujlwm ntawd yog, tab sis ntawm no yog phau ntawv qhia uas kuv tau ua raws. Links piav qhia tias VOCs yog dab tsi thiab vim li cas koj thiaj xav saib xyuas: -Sau qee cov tsos mob ntawm ntau dhau rau VOCs-OSHA txoj cai ntawm formaldehyde qib-cov ntaub ntawv ntawm mob lub tsev mob: 'Xyoo 1984 Pawg Neeg Saib Xyuas Kev Noj Qab Haus Huv Hauv Ntiaj Teb tau tshaj tawm tias txog li 30 feem pua ntawm cov tsev tshiab thiab kho dua tshiab thoob ntiaj teb tuaj yeem yog qhov kev tsis txaus siab ntau ntxiv ntsig txog huab cua sab hauv tsev (IAQ).'- Sab Hauv Zaj Dab Neeg: Phau Ntawv Qhia rau Sab Hauv Huab Cua Zoo: "Rau cov pa phem uas tsis yog radon, kev ntsuas yog qhov tsim nyog tshaj plaws thaum muaj cov tsos mob los yog cov pa tsis zoo thiab cov peev txheej tshwj xeeb lossis cov pa phem tau raug txheeb pom tias ua rau muaj teeb meem huab cua sab hauv tsev. Ua ntej tshuaj xyuas koj lub tsev rau cov pa phem tshaj li radon, sab laj nrog koj lub xeev lossis hauv cheeb tsam kev noj qab haus huv lossis cov kws tshaj lij uas tau muaj kev paub daws teeb meem huab cua sab hauv tsev tsis zoo. vaj tse strial."

Kauj ruam 1: Sau koj cov khoom siv

Koj yuav xav tau: -an Arduino (lossis sib npaug) -a cable los txuas Arduino mus rau koj lub khoos phis tawj / muab lub zog-lub khoos phis tawj nyeem qhov tseem ceeb-lub zog lossis lub zog tiv thaiv ntawm tus nqi paub. nyob qhov twg los ntawm 500-1k ohms yuav tsum ua haujlwm-lub ntsuas pa: qhov mob yuav hauv qhov me me. Kuv yuav 2 thiab lawv raug nqi zoo li $ 22 txhua, tab sis ntim xaj kom tau txais txoj kev pheej yig dua … qhov tshwj xeeb sensor kuv siv yog figaro sensors's 2620. Nov yog qhov kuv siv: -qhov khoom siv arduino kuv siv-qhov sib txawv sensors muaj los ntawm Figaro (siv cov ntsuas sib txawv rau 'tsis hnov tsw' yam sib txawv) Nws 'muaj txiaj ntsig tab sis tsis tsim nyog kom muaj lub multimeter thiab cov xaim hluav taws xob nqa tau yooj yim … Cov ntawv pdf suav nrog cov kauj ruam no yog tus nqi teev los ntawm cov chaw tsim khoom lag luam raws li lub Peb Hlis 2008.

Kauj ruam 2: Teeb Koj Arduino

1. Tau koj Arduino txuas nrog koj lub khoos phis tawj thiab ua haujlwm tau qhov no yuav tsum ncaj ncaj, tshwj xeeb tshaj yog nrog ib qho tshiab Arduino. Phau ntawv qhia no ua haujlwm rau kuv. 2. Program koj Arduino kom nyeem tus nqi los ntawm cov lus sib piv thiab tso saib qhov no ntawm-screen. Kuv siv -qhia qhia rau siv lub hwj chim ntsuas nrog arduino thiab tsuas yog hloov kho qhov zaus uas nws nyeem tus nqi nkag (ncua (100) = nyeem 10 zaug hauv ib pliag) kom tau txais cov cai hauv qab no, uas ua haujlwm rau kuv: // qhov no tso tawm cov lauj kaub tus nqi rau tshuaj ntsuam hauv ohmsint gasSensor = 0; // xaiv tus pin nkag rau gasSensorint val = 0; // sib txawv los khaws tus nqi los ntawm kev teeb tsa sensorvoid () {Serial.begin (9600);} void loop () {val = analogRead (gasSensor); // nyeem tus nqi los ntawm lub potSerial.println (tus nqi); ncua (100);} Yog tias koj siv qhov no raws li koj thawj qhov kev zam txim rau ua si nrog Arduino, koj yuav xav sim tsuas yog txuas lub hwj chim thiab nyeem tus nqi los ntawm nws ua ntej ntxiv lub sensor.

Kauj Ruam 3: Tsim Koj Li Circuit Court

Daim duab txuas yog daim duab ntawm Circuit Court los saum toj saud (lub ntsiab lus hais tias lub sensor qhov taw qhia tau taw qhia rau hauv av; muaj me ntsis hlau tab tawm los ntawm lub sensor kom koj nkag siab tias tus pin yog leej twg. Tsis tas li, tshawb xyuas daim duab qhia rau tshwj xeeb lub sensor uas koj xaiv. Txuas nrog yog cov ntawv teev tseg, nrog qee qhov piv txwv ntawm Circuit Court, rau 2620.

Txog rau 2620, cov ntawv teev tseg yam tsawg kawg 450 ohms tsis xav tau. Kuv tau kho kuv lub hwj chim rau ~ sab xis ntawm 450 ohms. Hauv cov lus Askiv yooj yim, ntawm no yog kev sib txuas koj yuav xav ua: -sensor pin 1 rau tus pin sab nraud ntawm potentiometer thiab hauv av (arduino av) -sensor pin 2 rau lwm tus pin sab nraud ntawm potentiometer -sensor pin 3 rau arduino +5 v thiab sensor tus pin 4 -middle tus pin ntawm lub hwj chim rau arduino analog 0 input Koj tuaj yeem siv qhov no (nyeem Figaro ceeb toom ntawm hom tshuaj dab tsi thiab ntsuas kub ntawm cov ntsuas), tab sis lub khob cij yog qhov zoo txaus rau kuv lub hom phiaj.

Kauj Ruam 4: Kuaj Koj Qhov Kev Pom Zoo Tshiab ntawm Qhov Ntxhiab

Nrog txhua yam txuas nrog, koj tau npaj yuav nqes tus arduino mus rau koj lub khoos phis tawj, tua hluav taws ib puag ncig arduino, thiab pib nyeem qhov tseem ceeb. Tsis txhob hnov qab (zoo li kuv tau pib ua:)) txhawm rau ntaus 'saib cov ntawv nkag mus' khawm hauv software arduino.

Koj mam li pib pom qhov tseem ceeb nqes mus rau qhov chaw dub nyob hauv qab ntawm qhov program arduino. Cov txiaj ntsig no yog qhov tsis kam, hauv ohms, raug nyeem los ntawm Circuit Court. Txhawm rau sim, tshuab qeeb yam tsawg kawg ob peb feeb dhau ntawm lub sensor. Cov lej ntawm qhov screen yuav tsum hloov. Kuj sim tuav lub sensor hla cov tshuaj siab ua kom nws yuav tsum pom: kuv tus nqi dhia me ntsis ua qhov no. Nrog ~ 4 hnub hlawv -hauv thiab qhov kub ib puag ncig ntawm 63F, qhov txiaj ntsig kuv tau nyeem hauv kuv lub tsev yog (uas yog qhov tsim nyog tsis muaj tshuaj lom neeg siv): -tau zaum hauv qhov cua qhib, tom qab lub ntsuas sov sov li ~ 1 feeb: 52 -treathing maj mam hla lub sensor rau ob peb vib nas this: 73 -holding sensor ncaj qha hla lub raj mis qhib cawv: 235

Kauj Ruam 5: Tsim Tawm

Tsis muaj hlawv hauv qhov hluav taws xob no rau ib lub lim tiam thiab ntxiv cov thermistor, qhov no tsuas yog qhov zoo rau kev nyeem cov tshuaj sib piv ntawm cov tshuaj: piv txwv li, yog tias koj xav tau xim 'qis-VOC', koj tuaj yeem tuav qhov no ntau dua qhib lub raj mis xim sib txawv (hauv ib chav ntawm qhov kub thiab txias) thiab tsim nyog xav tias muaj kev nyab xeeb me ntsis siv cov xim uas sau tus nqi qis tshaj. Pom tseeb, muaj lub siab phem (thiab tej zaum qee VOCs: Kuv tsis paub) tias qhov no tsis pom, tab sis nws yog qhov zoo me ntsis dua li tsis muaj dab tsi:-)

Txuas nrog yog pdf Figaro Sensors muab, nthuav qhia cov lus teb ntawm cov thermistors ntawm qhov kub sib txawv. Yeej tsis yog lub thermistor nkaus xwb koj tuaj yeem siv tau, tab sis yuav muaj txiaj ntsig zoo thaum koj tshawb xyuas koj tus kheej, qhov zoo dua ntawm qhov haujlwm no. Kev nthuav dav txias uas kuv xav pom yog txhawm rau ua kom pom qhov kwv yees qib hauv ib plhom (ppm) ntawm huab cua muaj kuab paug ntawm kuv nraub qaum thaum kuv caij kuv lub tsheb kauj vab hla kev tsheb, tej zaum nrog LED 'Mr. Yuck 'kos npe uas tig rau saum ib qho kev xav ib yam nkaus. Qhia rau kuv paub yam koj tsim, thiab muaj kev lom zem!
