Cov huab cua tam sim no saum toj roob hauv Hawaii muaj li ntawm 400 ppm ntawm Carbon Dioxide. Tus lej no tseem ceeb heev rau txhua tus uas nyob saum lub ntiaj teb. Peb tau nyob ib puag ncig tam sim no los ntawm qhov tsis lees paub qhov kev txhawj xeeb no lossis cov neeg uas tuav lawv txhais tes hauv qhov kev ntxhov siab ntxhov siab. Tab sis tus lej no thiab ntau txhiab tus lej uas ua raws nws hauv xov xwm yog qhov nyuaj rau nkag siab tiag tiag nyob rau niaj hnub. Tus nqi CO2 nyob ib puag ncig kuv yog dab tsi? Kuv tuaj yeem cuam tshuam nrog lub tswv yim ntawm cov pa cua hauv huab cua ua rau lub ntiaj teb sov li cas? Rau cov uas xav paub Kuv tau tsim Giant Analog CO2 meter uas nrog kev pab ntawm 4 ko taw ntev rab koob yuav ua rau muaj kev sib tham ntawm txhua chav tsev kawm ntawv lossis tsev khaws puav pheej ntawm yuav ntsuas CO2 li cas thiab koj tuaj yeem dhau los ua ib feem ntawm qhov kev ntsuas roj no li cas.

Los ntawm kuv txoj haujlwm nrog tshuaj xyuas cov khoom sib xyaw roj hauv snorkels: https://www.instructables.com/id/CO2-Measurement-in-Snorkels/ thiab kev lom zem ntawm kev tsim cov dej ntws loj heev: https://www.instructables.com/ id/ Giant-Tide-Clock/ Kuv tau rov txhim kho lub CO2 sensor thiab lub tshuab ua haujlwm ruaj khov los ua phab ntsa mount Analog CO2 meter uas yog qhov tseeb qhia txog qib CO2 tam sim no hauv huab cua. Feem ntau ntawm kev tsim yog 3D luam tawm thiab nws kuj tseem muaj qhov tso tawm digital raug los ntawm Adafruit plaub E - Ink zaub. Cov pa hnoos hws ntawm lub ntsuas qhov ntsuas yog qhov zoo kawg nkaus STL cov ntaub ntawv los ntawm: Hloov kho 3 nti Spiral Speaker lub thawv los ntawm iiime uas tau xub ua tiav rau Nautilus hais lus thaiv. Nws ua haujlwm ntawm cov roj teeb uas them rov qab lossis cov pob zeb ntawm 5 volts thiab yuav sau tag nrho koj cov ntaub ntawv mus rau hauv daim npav SD nrog.

Cov ntaub ntawv tsim kho tsis yog pheej yig tab sis ntxiv rau qhov tseeb qhov tseeb ntawm kev nyeem.

1. Adafruit 2.13 Tri-Color eInk / ePaper Display FeatherWing-Liab Dub Dawb-koj tuaj yeem siv TFT pheej yig heev rau qhov no rau $ 3.00 tab sis nws yuav tsis tshwm zoo li nyob hauv tshav ntuj. hais tias nws yog qeeb kom tshiab.

2. Adafruit Feather 32u4 Adalogger - MO version ntawm cov cuab yeej no tsis ua haujlwm zoo nrog lub ntsuas cua. Koj tuaj yeem tau txais nrog qhov pheej yig dua 32u4 chav tsev tsis muaj daim npav SD daim npav tab sis qhov no ua rau nws yooj yim dua yog tias koj xav sau tag nrho koj cov ntaub ntawv.

3. Rugged Hlau On/Off Hloov nrog Blue LED Ring - 16mm Xiav On/Off

4.10, 000ppm MH-Z16 NDIR CO2 Sensor nrog I2C/UART 5V/3.3V Interface rau Arduino/Raspeberry Pi los ntawm Sandbox Electronics-qhov teeb meem zoo tiag tiag tsis muaj kev paub nrog lub tuam txhab no kom ntseeg tau tias koj ua raws cov lus qhia rau kev tso tawm 3 volt tso tawm- nws tsuas yog ua haujlwm ntawm 5 volts

5. Txheem Hub Ncej ServoBlock ™ (24T Spline) ServoCity - lwm lub tuam txhab zoo! (Kuv tsis tau txais txiaj ntsig los ntawm kuv qhov kev pom zoo ntawm cov tuam txhab no)

Cov khoom siv tau yooj yim luam tawm nrog PLA ntawm txhua lub tshuab luam ntawv 3D. Qhov pheej yig Creality CR10 uas kuv tau siv muaj qhov dav txaus tso tawm kom pab tau qhov loj ntawm lub suab raj thiab sab nraub qaum. Nws siv sijhawm ntau teev tab sis tsis muaj teeb meem ntsib. Luam nrog kev txhawb nqa. Tom qab ntawd lub horn tau txau nrog cov xim pleev xim uas ua rau cov av zoo li cov khoom kawg thiab npog cov kab zoo ntawm 3D luam tawm. Sab nraub qaum tau tsim hauv Fusion 360 kom yooj yim haum rau lub qhov rooj ntawm Feather E number case zaub. Lwm cov ntaub ntawv yog rau cov ntsia hlau ntawm tus tuav rau tus pointer pas nrig thiab cov ntaub ntawv uas tuav lub counterweights rau hauv qab ntawm tus pointer.

Kev tsim kho yog yooj yim zoo nkauj. Qhov kev pabcuam ua haujlwm ua rau koj ua haujlwm sai sai rau servo mechanism mus rau cov qauv kev txhawb nqa. Cov ntawv txuas txuas rau sab xub ntiag nrog lub phaj rov qab uas suav nrog txhua yam khoom siv hluav taws xob tau ua nrog ob daim hlau txuas txuas uas yog E6000 glued rau tom qab ntawm phaj. Lwm lub phaj txuas txuas sab nraub qaum kom pab tau cov khoom sib txuas mus rau 90 degree phab ntsa txuas. Tus pointer uas kuv siv tuaj yeem ua qhov tseem ceeb txhua qhov ntev-kuv qhov loj me yog li 4 ko taw. Kuv tau siv txoj kab tsheb npav ntev uas koj tuaj yeem pom hauv khw lub thawv loj rau qis dua $ 5. Lawv tau ua los ntawm fiberglass thiab zoo nkauj thiab lub teeb rau lawv qhov ntev. Hauv qhov xwm txheej nrog servo txawm tias muaj kev txhawb nqa lub zog koj yuav tsum ua tib zoo sib npaug qhov hnyav thiab ua kom ncaj nruab nrab nws hauv qhov siab. Kuv qhov hnyav tau ua nrog lub tshuab ntxhua khaub ncaws hauv lub tsev luam ntawv 3D thiab tom qab ntawd kaw nrog qhov txiav kawg ntawm tus ncej hauv epoxy. Ua kom ntseeg tau tias qhov kev pabcuam ua haujlwm tiv thaiv qhov kev sib tw no thiab kev sib tw los ntawm kev sim nws tawm-cov servo yuav tsum tsis txhob yws tom qab nws mus txog nws txoj haujlwm hauv software. Yog tias nws tseem yws yws thiab txav koj feem ntau yuav muaj teeb meem.

Daim duab kab hluav taws xob muaj nyob rau saum toj no. Tus pin servo txuas nrog tus pin 11 hauv qhov xwm txheej no. Daim ntawv E ntawv siv qee tus pin ntawm cov plaub yog li tsis txhob siv lawv. Nco ntsoov tias SDA, SCL khub tau txuas nrog kom raug. Lub zog ua tiav los ntawm ib qho 5 volt phab ntsa wart (2 A) lossis Lipo Battery. Wart ntawm phab ntsa tau hla los ntawm ON/Off hloov pauv nyob rau sab saum toj ntawm lub suab nrov uas tom qab ntawd ua rau lub zog plaub hau tshuab, servo thiab ntsuas tag nrho nrog 5 Volts. Kuv kuj txuas ib qho ntawm Blue LED's mus rau qhov kawg ntawm lub tshuab raj ua ke kom muab qee lub teeb nyob rau thaum kawg ntawm qhov av. (Qhov no tsis nyob hauv daim duab kab hluav taws xob.) Lub laser sensor rau CO2 tau teeb tsa ze rau ntawm lub qhov rooj qhib kom koj tuaj yeem tshuab rau nws lossis muab lwm yam sib xyaw cua nkag mus rau nws lub qhov ncauj. Lub rooj tsav xwm digital rau nws kuj tau teeb tsa sab hauv lub tshuab raj thiab lub zog sib txuas tau ncaj qha mus rau qhov hloov. Cov xov hlau hauv av, cov xov hluav taws xob thiab SDA, SCL cov kab raug coj tawm sab nraum qab ntawm lub phaj mus rau Rooj Plaub Ntoo. Adalogger Feather/ E ntawv tso saib pawg tau muab tso rau tom qab ntawm lub phaj. Tom qab txhua qhov kev sib txuas raug sim lub tshuab raj kaw rau sab nraub qaum nrog E6000 kua nplaum ib hmos.

Qhov program yooj yim heev nrog Arduino IDE. Suav nrog ntau lub tsev qiv ntawv rau cov tshuab txuas: NDIR_I2C.h (suav nrog hauv Sandbox Electronics lub vev xaib), "Adafruit_EPD.h" rau kev ua haujlwm zoo nkauj E-ntawv zaub, Servo.h rau cov tsev qiv ntawv servo txheem. Txhais cov pins tsim nyog rau cov zaub. Txheeb tus pin rau servo cov zis. Txuas lub Servo thiab lub sensor. Lub voj muaj nuj nqi tsuas yog nyeem lub sensor thiab tso tawm nws mus rau servo nrog Daim Ntawv Qhia/Kev txwv ua haujlwm. Ib qho uas tsis yooj yim tsuas yog txwv koj qhov kev pabcuam kom nws thiaj li tsis tsoo rau sab ntawm lub roob. Kuv nyiam lub tswv yim ntawm sab nraub qaum rau qhov servo/pointer encapsulated ntawm lub ntsej muag phaj thiab phab ntsa tom qab tab sis nws kuj muaj qee qhov txwv. Siv tus qauv piv txwv kev ua haujlwm txhawm rau ntsuas tawm lub kaum sab xis txwv rau servo thiab txwv lawv hauv daim ntawv qhia ua haujlwm. Cov lus rau qhov kawg yog txwv qhov nrawm ntawm servo kom lub zog ntawm tus pointer caj npab ntev tiv thaiv tsis ua rau cov duab puab.

Cov cuab yeej tau yooj yim teeb tsa rau ib sab phab ntsa nrog ob peb tus ntsia hlau. Nws tsis hnyav li ntawd thiab txij li nws qeeb qeeb tiag tiag tsis viav vias ncig ntau. Hauv thawj GIFF koj tuaj yeem pom tias nws tsis nkag siab zoo rau CO2 txawm tias koj ua pa. Ua pa mus rau qhov kawg ntawm lub suab nrov nce cov peev xwm CO2 mus rau 4% uas yuav yog 40, 000 ppm. Lub ntsuas hluav taws xob mus rau qhov ntsuas ntawm 10, 000 thiab koj tuaj yeem cuam tshuam nrog qhov no hauv cov phiaj xwm ntawm kev txav mus los-piv txwv li ua cov logarithmic tso tawm lossis hloov lub voj voog txav nrog nrawm nrawm. Lwm qhov kev sim tuaj yeem ua tiav nrog nws suav nrog muab nws tso rau hauv chav me me uas muaj coob tus neeg (hauv tsev teev ntuj hauv qab thaum lub lauj kaub-hmoov) lossis sab nraum ntawm cua daj cua dub saum toj roob. Qhov qis tshaj kuv tau txais yog txog 410 thiab uas yog nrog 50 mph cua daj cua dub nag hmo. Qhov muaj peev xwm siv cov cuab yeej no yuav yog kom paub cov tib neeg nrog lub tswv yim ntawm CO2 kev saib xyuas thiab nws qhov tseem ceeb - tsis yog qee qhov tsis paub daws teeb uas hais lus taub hau tab sis qhov peb tuaj yeem ntsuas tau hauv peb chav kawm lossis tsev cia puav pheej.

Tsis txhob tawm tsam qhov xav ua ib feem ntawm kev daws teeb meem txaus ntshai no los ntawm kev kawm lossis hais tawm.
