Kauj Ruam 1: Kev Npaj Vaj & Dej

Nco ntsoov npaj koj cov dej npaj tseg yog tias koj tab tom tsim cov txheej txheem tshiab. Nws yuav yog qhov tseem ceeb kom muaj cov khoom no twb tau muaj lawm thaum koj mus npaj kho vajtse kom koj paub koj cov khoom xav tau. Kev xav tau tuaj yeem hloov pauv lub sijhawm tab sis nws yog kev coj ua zoo los npaj rau yav tom ntej. Koj ob qhov kev xaiv tseem ceeb ntawm kev xa dej yog siv lub twj tso kua mis hauv cov dej tso dej lossis lub qhov dej nrog lub solenoid qhib thiab kaw kab. Qhov kev xaiv yuav yog nyob ntawm koj nyob ntawm koj lub vaj xav tau. Cov txheej txheem loj dua tuaj yeem siv ob qho tib si (piv txwv li tso dej los ntawm solenoids li qub rau thaj tsam dej). Yog tias koj npaj yuav siv MudPi sab hauv tsev koj yuav zaum siv lub twj tso kua mis yog tias muaj dab tsi. MudPi tuaj yeem tswj hwm koj lub teeb tsob ntoo sab hauv tsev siv kev xa khoom ib yam nkaus.

Maker Tip: Nco ntsoov koj tuaj yeem tsim koj txoj haujlwm ntawm txhua qhov loj me. Yog tias koj tsuas yog xav sim MudPi thawj zaug sim ib yam dab tsi zoo li lub raj mis dej thiab 3.3v lub twj tso kua dej rau hauv tsev!

Kuj xav txog kev xaiv xa dej. Koj puas yuav siv cov kab txau, lub soakerhose lossis cov kais tsuag dej? Nov yog ob peb txoj hauv kev:

• Sprinkler
• Soakerhose
• Txau kab
• Los ntawm txhais tes dej

Txhawm rau ua kom dav ntawm qhov kev qhia no los ntawm kev loj hlob loj heev cia xav tias koj twb muaj dej nyob hauv qhov chaw thiab tsuas yog xav ua kom siv tau nws. Hauv kuv qhov teeb tsa kuv muaj lub tank dej nrog lub twj tso kua mis sib txuas mus rau qee txoj kab dej. Cia peb kawm paub yuav siv lub twj tso kua mis li cas.

Kauj Ruam 2: Kev Tshawb Fawb & Kev Npaj Ua Haujlwm

Lwm qhov kev npaj tseem ceeb los txiav txim siab yog cov ntaub ntawv twg koj yuav xav tau los ntawm koj lub vaj. Feem ntau qhov kub thiab txias yog ib txwm muaj txiaj ntsig. Cov av noo thiab nrhiav pom nag yog qhov zoo tab sis yuav tsis xav tau kev teeb tsa sab hauv tsev. Nws yuav yog koj qhov kev txiav txim siab zaum kawg ntawm yam xwm txheej twg yog qhov tseem ceeb los saib xyuas koj li kev xav tau. Rau peb qhov kev qhia sab nraum zoov peb yuav saib xyuas:

• Kub
• Vaum
• Cov dej (ntab hloov x2)

Kuv siv 5 lub ntsuas dej ntsuas ntsuas qib 10%, 25%, 50%, 75%thiab 95%hauv lub tank loj. Hauv qhov kev qhia no peb yuav ua 10% rau qhov tseem ceeb qis thiab 95% puv rau qhov yooj yim.

Koj kuj tseem xav tswj cov cuab yeej hauv koj lub vaj. Yog tias koj npaj yuav hloov lub twj tso kua mis lossis lub teeb uas tsis ua haujlwm ntawm 3.3v (tus lej GPIO txwv) ces koj yuav xav tau kev xa rov qab. Kev xa rov qab tso cai rau koj los tswj cov hluav taws xob hluav taws xob ntau dua thaum siv qis dua hluav taws xob los hloov qhov kev xa tawm. Rau peb lub hom phiaj peb muaj lub twj tso kua mis uas khiav ntawm qhov hluav taws xob siab dua 3.3V yog li peb yuav xav tau kev xa mus los hloov lub twj tso kua mis. Tsuas yog ib qho kev xa tawm xwb xav tau los tswj lub twj tso kua mis. Txawm hais tias rau yav tom ntej lub hom phiaj (thiab vim tias kev xa khoom pheej yig) Kuv tau teeb tsa 2 channel xa tawm thiab sab laug qhov txuas ntxiv muaj rau tom qab hloov khoom dua tshiab.

Qhov tseem ceeb tshaj plaws rau kev npaj yog kev siv fais fab. Yuav ua li cas Pi yuav raug siv thiab qhov twg los. Tsis tas li koj yuav tsum xav txog cov cuab yeej koj siv thiab yuav ua li cas lawv thiaj li muaj zog. Feem ntau Pi tuaj yeem siv tau los ntawm lub tshuab hluav taws xob usb tab sis qhov ntawd yuav tsum tau ntsaws ntawm nws tus kheej. Yog tias peb tab tom txhawb lwm yam khoom siv uas muaj hluav taws xob ntau dua DC rau DC cov khoom siv hluav taws xob tuaj yeem siv rau theem hluav taws xob qis rau 5v rau Pi. Yog tias koj npaj yuav tau txais lub hwj chim txhawm rau txo qis qhov hluav taws xob Kuv pom zoo kom tsis mus nrog qhov kev xaiv pheej yig tshaj.

Nco ntsoov Raspberry Pi tuaj yeem txhawb nqa digital GPIO nkaus xwb. Qhov no txhais tau tias koj tsis tuaj yeem cia li nqes tus ntsuas qhov av uas siv cov lus sib piv rau Pi GPIO. Txhawm rau kom ua tau zoo sib xws nrog cov khoom sib piv koj yuav tsum tau siv lub micro-maub los nrog kev txhawb nqa analog xws li Arduino lossis ESP32 (lossis ESP8266).

Luckily MudPi muaj kev txhawb nqa rau kev tswj hwm cov cuab yeej zoo li qhev qoj rau cov lus txib rau ntau yam khoom siv los ntawm ib tus tswj hwm tseem ceeb (pi). Qhov no ua rau nws muaj peev xwm muaj lub maub los tseem ceeb nrog ntau lub ntsuas qhov ntsuas uas nws tuaj yeem tswj hwm nrog lawv cov khoom sib txuas sib piv. Kuv siv lub maub los tseem ceeb los saib xyuas thaj chaw tso twj tso kua mis thiab chav ntsuas ntsuas rau txhua lub txaj hauv vaj. Hnub no cia txuas ntxiv tsim tus tswj hwm tseem ceeb kom pib.

Kauj Ruam 3: Sau cov khoom siv

Nws yog lub sijhawm rau peb los sau peb cov ntaub ntawv. Cov khoom siv thiab cov cuab yeej siv hauv kev tsim no yog txhua yam lag luam tawm ntawm cov khoom txee kom yooj yim rau lwm tus los tsim lawv tus kheej hauv tsev. Feem ntau tuaj yeem pom hauv online lossis ntawm cov khw muag khoom kho vajtse hauv cheeb tsam. Qhov nqi ntawm cov ntaub ntawv yuav nyob ntawm koj lub vaj tshwj xeeb. Txog rau qhov kev qhia no peb yuav khaws cov khoom mus rau qhov tseem ceeb raws li tau npaj tseg kom tau txais chav ua haujlwm ua ntej mus ntxiv.

Nco tseg: Kuv xav sau tseg ntawm qhov no yog tias koj npaj yuav hloov pauv cov khoom siv uas tawm ntawm qhov hluav taws xob qhov hluav taws xob thov CAREFUL! Nws yog ib qho tseem ceeb uas koj muaj kev nyab xeeb thaum tsim hluav taws xob thiab tsis txhob tinker nrog cov hluav taws xob siab yog tias koj tsis paub tias koj tab tom ua dab tsi. Nrog qhov hais tias kuv tau siv lub twj 120v hauv kuv lub tsev teeb tsa. Cov txheej txheem yog tib yam rau lub twj tso kua mis 12v nrog qhov sib txawv tseem ceeb xav tau 12v tus tswj hwm. Koj kuj tseem tuaj yeem siv txuas mus rau teeb lub teeb lossis lwm yam khoom siv.

Kauj Ruam 4: Nruab MudPi ntawm Raspberry Pi

Nqa cov hlua txuas mus rau hauv vaj tse nrog silicone calk kaw qhov seem ntawm hauv qab ntawm lub tsev yog li tsuas yog lub qhov cua nkag yog qhov nkag.

Lwm qhov kawg ntawm txoj kab koj tuaj yeem khiav mus rau hauv lub thawv los ntawm cov kab txuas txuas thiab txuas rau Pi ntawm tus pin tib yam li ua ntej. Yog tias koj xaiv siv ntsaws ntsaws ntsaws ntsaws ntsaws rau hauv kab. Laum thiab nruab lwm qhov kawg rau hauv lub thawv sib txuas thiab tom qab ntawd txuas rau sab hauv.

Kauj Ruam 12: Nruab Float Sensors Rau Hauv Tank

Nrog rau lwm qhov kev tiv thaiv thiab npaj mus nws lub sijhawm los teeb tsa cov ntab sensor rau hauv lub taub dej. Txij li thaum peb tsuas yog siv ob qho koj yuav tsum teeb tsa 1 ntawm qhov tseem ceeb qis uas lub twj tso kua mis yuav tsum tsis txhob khiav thiab ib qho uas yuav tsum cim lub tank puv. Nrhiav qhov ntsuas me me kom raug thiab ua lub qhov rau hauv lub tank ntawm qib raug. Ntsia cov ntab sensor rau hauv lub tank nrog lub tshuab ntxhua khaub ncaws thiab txiv ntseej muab. Saib sab hauv lub tank thiab nco ntsoov tias lub ntsuas dej ntab tau taw qhia kom lawv nyob hauv qhov chaw tawm thiab tsa thaum dej nce ua rau lawv kaw lub Circuit Court.

Vim yog qhov rub tawm qhov ntsuas no txhais tau tias thaum qib dej tau ntsib lub ntab sensor ntawm qib ntawd nrog nyeem 1. Txwv tsis pub lub ntab sensor yuav rov qab 0 yog tias tam sim no cov dej tsis tam sim no rub lub sensor kaw lub Circuit Court.

Kauj Ruam 13: Tso Lub Tsev Sab Nraud

Chav MudPi tau npaj tiav thiab peb tuaj yeem rub nws sab nraum nws qhov chaw zaum kawg. Lub thawv sib txuas sab nraum zoov feem ntau tuaj nrog lub hau ntswj kom ua rau cov dej kaw nruj. Koj kuj yuav tsum pom qee qhov kev teeb tsa nyob tom qab kom siv rau kev teeb tsa chav nyob. Kuv tau teeb tsa kuv lub npov nyob ib sab ntawm cov dej ntws tawm sab nraum vim tias cov ntab sensor tsuas muaj qhov txwv tsis pub siv cable.

Koj tuaj yeem ntsaws tus txiv neej txuas txuas rau hauv lub qhov (socket) thiab ntxeev lub tawg kom nqa MudPi online. Nco ntsoov tias txhua yam ua haujlwm ua ntej tawm mus rau lub sijhawm txuas ntxiv. Kuaj tias cov ntsuas ntsuas tau nyeem los ntawm saib mus rau redis rau khaws cov txiaj ntsig lossis txheeb xyuas MudPi cav. Yog tias txhua yam zoo li zoo nws yog lub sijhawm cia MudPi ua haujlwm thaum koj so.

Kauj Ruam 14: Saib Xyuas MudPi

Tam sim no MudPi tab tom ua haujlwm koj yuav xav tsis thoob txog txoj hauv kev los saib xyuas koj li kab ke. Txoj hauv kev yooj yim tshaj plaws thiab ncaj tshaj yog saib xyuas MudPi cov ntaub ntawv teev cia:

tw -f /home/mudpi/logs/output.log

Lwm qhov kev xaiv yog los ntawm kev cuam tshuam zoo li lub vev xaib hauv zos. Kuv tsis tau muaj sijhawm los tshaj tawm MudPi UI rau pej xeem tseem tab sis koj tuaj yeem yooj yim tuav koj lub ntsuas thiab lub xeev tiv thaiv los ntawm redis nrog PHP. Kawm paub yuav ua li cas MudPi khaws koj cov ntaub ntawv hauv redis ntau hauv cov ntawv.

Qhov ntsuas qhov ntsuas kawg yuav raug khaws cia hauv redis hauv qab qhov kev xaiv tseem ceeb koj teeb tsa hauv kev teeb tsa. Siv qhov no koj tuaj yeem ua daim ntawv thov PHP yooj yim kom rub cov nyeem ntawm nplooj ntawv thauj khoom thiab tso saib lawv. Tom qab ntawd tsuas yog rov ua nplooj ntawv tshiab rau cov ntaub ntawv tshiab.

Nws kuj tseem tuaj yeem mloog MudPi cov xwm txheej ntawm redis thiab qhov no yog qhov kev xaiv zoo dua kom tau txais qhov hloov tshiab ntawm lub sijhawm. Koj tuaj yeem nyeem cov xwm txheej ncaj qha los ntawm redis-cli

redis-cli psubscribe '*'

Kauj Ruam 15: Hloov Cov Qauv Txheej Txheem Nrog PCBs Kev Cai (Yeem Xaiv)

Kuv tau mus deb me ntsis thiab ua qee qhov kev cai tswj hwm ib yam nkaus rau MudPi. Lawv pab kuv kom nrawm cov txheej txheem tsim nrog tsim ntau lub tsev MudPi thiab muaj kev ntseeg siab dua. Kuv tau pib hloov pauv kuv cov laug cam qub nrog cov PCBs uas ntseeg tau ntau hauv txhua chav uas kuv muaj. Yav tom ntej kuv xav ua cov laug cam no muaj muag hauv qhov me me los pab txhawb kuv txoj haujlwm qhib. MudPi tsis xav tau ib qho kev cai tswj hwm lub rooj tsav tsheb, nws tsuas yog pab txo qis kev ua haujlwm ntawm lub khoos phis tawj nrog cov khoom siv sab hauv uas twb tau teeb tsa xws li rub tawm cov neeg tawm tsam thiab ntsuas kub/av noo.
