Kho vajtse tshiab yuav npaj tau tsuas yog ob peb lub lis piam tab sis txog thaum ntawd kuv tab tom tso tawm firmware tshiab. Qhov software no yuav pab tshem qee qhov teeb meem. Mus rau qib 12 kom paub ntau ntxiv. Thiab tseem ceeb tshaj, txaus siab!

Kauj Ruam 1: Tsim

Kev tsim lub chaw nres tsheb huab cua yog txheej txheem ntev thiab xav tau. Koj muaj ntau txoj kev xaiv los xaiv. Nov yog cov tseem ceeb uas koj yuav tsum xav txog thaum tsim lub chaw nres tsheb huab cua (lossis tsawg kawg kuv tau ua):

1) BUAG. Qhov no zoo nkauj piav qhia tus kheej.

2) LAWV. Qhov no tseem ceeb heev vim nws cuam tshuam rau kev teeb tsa nrog rau kev sib txuas lus thev naus laus zis thiab lub zog xav tau. Cov chaw huab cua nyob deb xav tau cov chaw xa xov ntev thiab muaj peev xwm siv tau tus kheej xws li lub hnub ci vaj huam sib luag.

3) MEASURED VARIABLES. Koj puas tsuas xav ntsuas kub lossis av noo? Tom qab ntawd koj tuaj yeem tso tus sojntsuam ze rau txhua qhov chaw. Tab sis yog tias koj xav ntsuas dej nag, cua, hnub ci tawg, ntsuas UV lossis lwm yam khoom cuam tshuam nrog lub hnub lossis nag lossis daus tom qab ntawd lub ntsuas cua tsis tuaj yeem nyob hauv qhov ntxoov ntxoo thiab tsis tuaj yeem thaiv tsis tau los ntawm sab saud lossis sab.

4) ZOO SIAB. Koj puas xav kom koj qhov kev ntsuas ntsuas kom raug thiab piv rau lub koom haum huab cua hauv tebchaws lossis yog qhov kev nyiam ua qhov zoo txaus rau koj?

Yog li tam sim no koj yuav tsum muaj daim duab zoo nkauj ntawm yam koj xav tau. Yog li cia peb mus rau ntawm daim duab teeb duab! Nov yog qee txoj cai yooj yim uas kuv tau xav txog:

1) Tiv thaiv lub ntsuas kub. Koj yuav tsum ua qhov no kiag li. Cov cua sov tuaj yeem taug kev ntau txoj hauv kev nws tuaj yeem tawg thiab ua los ntawm cov qauv ntawm chaw nres tsheb nws tus kheej. Yog li sim ua lub tsho tag nrho ntawm cov hlau, thiab muab qhov ntsuas kub nyob hauv daim ntaub thaiv hluav taws xob. Kuv paub, kuv lub chaw nres tsheb hluav taws xob tsis zoo tab sis nws pab tau.

2) Tso lub qhov ntsuas qhov ntsuas siab kom siab. Cov cua cua yuav tsum tau muab tso rau 10m siab los ntawm cov qauv thoob ntiaj teb. Kuv tsis muaj nyiaj los yuav 10m tus ncej yog li 2m yeeb nkab saum lub ru tsev yog txaus rau kuv.

3) CLEAR AREA AROUND thiab saum toj no lub chaw. Yog tias koj xav ntsuas lub hnub ci koj tsis tuaj yeem muaj lub ntsuas cua nyob hauv qhov ntxoov ntxoo. Yog tias koj xav ntsuas cov dej nag koj tsis tuaj yeem muaj qee yam thaiv qhov nqes dej. Yog li xyuas kom tseeb tias thaj tsam ib puag ncig thiab siab dua qhov chaw nres tsheb tau raug tshem tawm.

Cia peb mus txuas ntxiv. Yog li, rau kuv qhov chaw nres tsheb Kuv txiav txim siab kuv xav ntsuas cov ntsuas no: Huab cua kub, av hauv av, txheeb ze huab cua, huab cua huab cua, ntsuas cua sov, taw tes lwg, cua txias, dej nag, hnub ci tawg, ntsuas UV, cua nrawm thiab cua qhia. Qhov no yog 8 qhov ntsuas nyob rau hauv tag nrho los ntawm qhov uas muaj 3 qhov me me, PCB-mountable modules thiab 5 qhov kev soj ntsuam sab nraud. Kuv yuav xav tau 2 cais microcontrollers, ib qho rau kev tswj xyuas cov dej nag xwb thiab qhov thib ob rau txhua yam ntxiv.

Kuv txiav txim siab muab txhua yam kuv ua tau rau ntawm PCB nkaus xwb. Kuv muab PCB tso rau hauv ib lub thawv IP65 nrog lub hau npog, kom lub hnub ci tuaj yeem hla mus rau lub hnub ci hluav taws xob thiab UV ntsuas qhov ntsuas. Tag nrho lwm qhov kev ntsuas yuav txuas nrog lub thawv tswj lub ntsiab nrog lub xov tooj. Yog li ntawd yog nws rau kuv tsim.

Kauj ruam 2: Huab cua

Nws tseem tuav qee qhov ntsuas uas suav nrog: BME280, BHT1750 thiab ML8511. Tom qab ntawd muaj DS3231 RTC module. Qhov kawg tab sis tsis tsawg, muaj qee qhov tiv thaiv thiab cov ntsia hlau txuas.

Kuv tsim kuv lub rooj tsavxwm hauv Autodesk Eagle. Tsuas yog rub tawm cov ntaub ntawv Gerber hu ua "ESP32 huab cua station.zip" thiab xa nws mus rau JLC PCB. Lossis yog tias koj xav kho nws, koj tuaj yeem rub tawm "ESP32 huab cua chaw nres tsheb schematic.sch" thiab "ESP32 huab cua chaw nres tsheb board.brd" cov ntaub ntawv thiab kho lawv hauv Eagle. Kuv xav qhia tswv yim rau npe kawm Circuit Board Design Class los ntawm Instructables ua ntej.

Kauj ruam 6: Soldering

Okay txhua tus, koj txhua tus tau ua qhov no ua ntej. Lub rooj tsav xwm zoo nkauj no uas kuv tau tsim muaj cov ntawv zoo silkscreen hneev taw luam tawm ntawm nws. Thaum koj muaj qhov ntawd, qhov yuav tsum tau ua ib qho ncuav mog qab zib vim tias koj pom qhov tseeb mus qhov twg. Tsuas muaj cov khoom THT nrog tus qauv 0.1 kev sib nrug.

Hloov kho 7/18/2020: RTC tus qauv tsis xav tau ntxiv lawm. Tsis tas yuav tsum tau teeb tsa nws ntawm lub rooj tsavxwm. Koj tuaj yeem kawm paub ntau ntxiv hauv qib 12.

Kauj Ruam 7: Ua Cov Khoom Siv Hluav Taws Xob

Thaum kuv tab tom tsim qhov no, kuv hais rau kuv tus kheej "Yog lawm, koj twb tau ua ob zaug no lawm tsis muaj caij nyoog uas koj yuav cuam tshuam tam sim no." Thiab kuv tsis tau.

Lub hnub ci thaiv hluav taws xob tiv thaiv hluav taws xob yog ib qho uas siv ntau hauv cov chaw huab cua los thaiv cov hluav taws xob ncaj qha hnub ci thiab yog li ntawd txo qhov ua yuam kev hauv qhov ntsuas kub. Nws kuj ua raws li tus tuav rau qhov ntsuas kub. Cov hluav taws xob thaiv hluav taws xob muaj txiaj ntsig zoo tab sis feem ntau yog ua los ntawm cov hlau thiab lawv tau kim heev yog li kuv txiav txim siab los tsim daim thaiv ntawm kuv tus kheej. Kuv tau ua Cov Lus Qhia uas qhia yuav ua li cas thiaj ua tau daim thaiv hluav taws xob zoo li no.

Kauj ruam 8: Tswj lub thawv

Qhov tseem ceeb ntawm qhov chaw nres tsheb no yog qhov pom tseeb ntawm lub thawv tswj. Nws tuav thawj thiab theem nrab microcontrollers, qee qhov ntsuas, RTC thiab qee yam tsis ua haujlwm. Tag nrho cov ntawd hauv pob IP65 yooj yim. Lub thawv muaj lub hau npog zoo li lub hnub ci tuaj yeem hla mus rau UV thiab lub hnub ci hluav taws xob ntsuas hluav taws xob.

Ua ntej peb tuaj yeem txhim kho PCB, peb yuav tsum npaj lub thawv rau cov hlua. Muaj tsib lub zog thiab cov ntaub ntawv txuas mus rau hauv lub thawv. Txhawm rau txhawb nqa cov khoom tsis muaj dej tsis zoo ntawm lub chaw nres tsheb, peb tab tom yuav xav tau cov kab hluav taws xob tsis muaj dej. Tshwj xeeb, ib qho PG7 rau lub zog txuas hluav taws xob, PG7 thib ob rau cua thiab dej nag ntsuas thiab peb PG11 rau ob qho ntawm qhov ntsuas kub. Kuv muab lub qog loj (PG11) tso rau hauv nruab nrab ntawm ib phab ntsa ntawm lub thawv thiab ob lub qog me me (PG7) hauv cov phab ntsa uas txawv. Yog li lub thawv hloov txheej txheem yog raws li hauv qab no:

1) Kos qhov chaw nruab nrab rau txhua lub qhov nrog tus cim.

2) Laum ib lub qhov me me nrog qhov siv me ntsis.

Kauj Ruam 9: PCB Mount

Txij li thaum kuv tsuas yog cov tub ntxhais kawm sim ntawm Autodesk Eagle, kuv tsis tuaj yeem tsim PCBs loj dua 8cm. Txhua yam haum rau pawg no yog li ntawd zoo. Tsuas yog teeb meem yog nrog lub thawv tswj. Lub rooj sib dhos mounting qhov suav nrog hauv lub thawv yog 14cm sib nrug. Qhov no txhais tau tias peb yuav xav tau tus tuav rau PCB. Qhov no tuaj yeem yog lub rooj tsavxwm (ntoo/yas/hlau) uas peb yuav nce lub PCB. Tom qab ntawd peb yuav muab tus tuav lub rooj rau lub thawv tswj. Txoj kev no PCB yuav raug nyab xeeb rau hauv lub thawv tswj.

Koj tuaj yeem ua tus tuav txawm koj xav tau. Koj tuaj yeem ua nws tus kheej los ntawm phaj ntoo lossis hlau, koj tuaj yeem laser txiav nws (zoo li kuv) lossis koj tuaj yeem txawm luam 3D nws. Kuv suav nrog qhov ntev ntawm pawg thawj coj saib yog li qhov kev xaiv yog koj li. Yog tias koj tau nkag mus rau lub tshuab txiav laser, tom qab ntawv txiav nws yog qhov yooj yim tshaj plaws. Koj tuaj yeem pom cov ntaub ntawv laser txiav ntawm no ob qho tib si hauv.pdf thiab.svg hom ntawv.

Raws li koj tuaj yeem pom kuv tau hla ntau yam kev hloov pauv ntawm tus tuav. Thaum kawg, Kuv tau mus nrog cov acrylic, vim nws tsis cuam tshuam los ntawm ya raws (zoo li ntoo) thiab nws tsis nyiam cua sov (zoo li hlau).

Kauj Ruam 10: Kev sib dhos + thaiv

Qhov no yuav yog qhov yooj yim zoo nkauj los ua, tab sis nyuaj heev rau piav qhia vim tias muaj ntau qib me me. Cia peb ua raws txoj cai ntawd:

Tom qab ntawd tsuas yog laum hla ob qho ntawm cov kav dej thiab ruaj ntseg lawv nrog cov ntsia hlau ntev. Mount tag nrho cov thawv thiab cov sensors. Qhov ntawd yog nws. Tam sim no koj lub chaw nres tsheb tau ua tiav tiav.

Peb tau ua qhov no rau hnub los nag. Nws nyuaj heev tab sis peb tsis muaj lwm txoj kev xaiv vim yog hnub kawg ntawm kev sib tw.

Kauj Ruam 15: Hwj chim, Txuas Txuas thiab Debugging

Koj lub chaw nres tsheb tau teeb tsa lub cev, tab sis nws tseem tsis tau online tam sim no. Cia peb ua tam sim no. Koj yuav tsum tau fais fab chaw nres tsheb li cas. Koj yuav tsum muaj tswv yim me ntsis ntawm no. Koj tuaj yeem tso tus adapter sab hauv ntawm lub tsev thiab rub kab ntawv hla lub qhov rais. Koj tuaj yeem faus cov kab hauv av. Koj tuaj yeem siv zog ntawm lub hnub ci vaj huam sib luag. Txhua qhov teeb meem yog tias muaj 5V 500mA ntawm tus pin ntawm lub hwj chim cable los ntawm lub thawv tswj. Nco ntsoov, txhua yam yuav tsum tsis muaj huab cua! Thaum koj muaj koj lub chaw nres tsheb siv, koj tuaj yeem txav mus rau qhov teeb tsa txuas thiab debugging.

Kev teeb tsa Uplink yog qhov pib tau txais ESP32 txhawm rau txuas rau koj li Wi-nkaus network. Yog tias nws nyob ntawm koj lub tsev, nws yuav tsum zoo. Yog tias nws nyob ntawm lub nkas-las lossis nyob deb dua, koj yuav xav tau Wi-Fi txuas ntxiv lossis txawm tias yog Wi-nkaus network kev cai. Tom qab ntawd qhov debugging theem ua raws. Koj tsuas tuaj yeem tso tus lej kawg thiab cia siab rau qhov zoo tshaj plaws tab sis kuv pom zoo tiag tiag sim ntsuas txhua qhov ntawm ib qho los ntawm ib qho xwb kom ntseeg tau tias txhua yam ua haujlwm tau zoo. Yeej tseem zoo ib yam li hauv qib 12. Yog txhua yam ua haujlwm zoo li nws yuav tsum tau, koj tuaj yeem tsoo lub UPLOAD khawm unplug USB cable thiab kaw ntawm lub thawv tswj.

Kauj Ruam 16: Ua Lub Neej Zoo Siab Tom Qab

Jeez, qhov no yog feeb kawg hais mav. Kuv pom qhov kev sib tw Sensors tsuas yog 10 hnub ua ntej nws xaus. Tib hmo ntawd, kuv yuav tsum ua zoo li 10 lub xov tooj los npaj txhua yam uas yuav tsum tau ua kom tiav qhov chaw nres tsheb. Nws tseem tsis tau tiav kiag li. Hnub peb yuav tsum tau teeb tsa lub chaw nres tsheb tau los nag loj heev cuam tshuam peb cov phiaj xwm. Kuv xav tau kom ua tiav tag nrho cov ntawv ua ntej qhov chaw nres tsheb tau ua tiav. Thaum kawg lub chaw nres tsheb tsuas yog niaj hnub no, nyob rau tib hnub kuv tau tshaj tawm Cov Lus Qhia no.

Muaj tseeb ntau yam uas tuaj yeem ua tau zoo dua ntawm no tab sis muaj ntau yam tseem ceeb uas koj tuaj yeem kawm ntawm no thiab siv lawv thaum tsim koj lub chaw nres tsheb. Yog tias koj tau ua txhua qib kom raug, tam sim no koj muaj lub chaw ua haujlwm huab cua ESP32 huab cua. Thiab yog ib yam! Txhua qhov kev ua haujlwm nyuaj tau them (Kuv vam tias nws tau ua). Koj tuaj yeem pom cov ntaub ntawv los ntawm kuv qhov chaw nres tsheb ntawm no. Yog tias koj muaj lus nug lossis lus pom zoo, kuv yuav zoo siab tau hnov lawv hauv cov lus hauv qab no.

Yog thiab kuj yog tias koj nyiam txoj haujlwm no Kuv yuav txaus siab heev yog tias koj tau pov npav rau kuv hauv kev sib tw Sensors. Ua tsaug ntau thiab txaus siab rau !!!

Thawj qhov khoom plig hauv kev sib tw Sensors
