DHT22 Environment Monitor
los ntawm taste_the_code
Kuv pib tshawb nrhiav Tus Pabcuam Hauv Tsev thiab txhawm rau kom muaj peev xwm pib tsim qee qhov automation, kuv yuav tsum muaj qhov ntsuas kub thiab av noo tam sim no los ntawm kuv chav nyob sab hauv kom kuv tuaj yeem ua raws li lawv.
Muaj cov kev lag luam daws teeb meem rau qhov no tab sis kuv xav tsim kuv tus kheej kom kuv tuaj yeem kawm tau zoo dua li Home Assistant ua haujlwm thiab teeb tsa cov cuab yeej siv nrog nws thiab ESPHome.
Tag nrho qhov project yog tsim los ntawm PCB kev cai uas kuv tsim los ua ib qhov project platform rau NodeMCU thiab tau tsim los ntawm kuv cov phooj ywg ntawm PCBWay. Koj tuaj yeem xaj lub rooj tsavxwm no rau koj tus kheej thiab muaj 10 daim tsim rau tsuas yog $ 5 ntawm: https://www.pcbway.com/project/shareproject/NodeMCU_Project_Platform_ce3fb24a.html

Kauj ruam 1: Kev cai PCB
Kuv tsim cov PCB no los ua qhov project platform tom qab siv sij hawm ntau heev rau kev cai NodeMCU tej yaam num ntawm prototyping PCBs.
PCB muaj txoj haujlwm rau NodeMCU, I2C li, SPI li, relays, DHT22 sensor nrog rau UART thiab HLK-PM01 fais fab mov uas tuaj yeem ua haujlwm ntawm AC mains.
Koj tuaj yeem tshawb xyuas cov vis dis aus ntawm kev tsim thiab xaj txheej txheem ntawm kuv YT channel.
Kauj Ruam 2: Solder cov Cheebtsam
Txij li thaum kuv tsis xav solder lub NodeMCU ncaj qha mus rau PCB, kuv siv poj niam pin headers thiab soldered lawv ua ntej ces kuv thiaj li ntsaws lub Node MCU rau lawv.
Tom qab cov headers, kuv soldered cov ntsia hlau terminals rau AC input nrog rau 5V thiab 3.3V outputs.
Kuv kuj tau soldered header rau DHT22 sensor thiab HLK-PM01 fais fab mov.
Kauj Ruam 3: Ntsuam Xyuas Qhov Voltages thiab Sensor
Txij li qhov no yog thawj zaug uas kuv siv PCB no rau ib qhov project, kuv xav kom paub tseeb tias kuv tsis tau messed ib yam dab tsi ua ntej txuas lub Node MCU. Kuv xav sim tawm board voltagyog tias txhua yam yog OK. Tom qab thawj zaug sim tawm 5V kev tsheb ciav hlau yam tsis muaj Node MCU ntsaws rau hauv, Kuv ntsaws rau ntawm Node MCU kom paub tseeb tias nws tau txais 5V thiab tseem hais tias nws tau muab 3.3V los ntawm nws cov tswj hwm onboard. Raws li kev xeem zaum kawg, kuv upload liample sketch rau DHT22 sensor los ntawm DHT Stable lub tsev qiv ntawv yog li kuv tuaj yeem tshawb xyuas tias DHT22 ua haujlwm zoo thiab kuv tuaj yeem nyeem tau qhov kub thiab av noo.
Kauj ruam 4: Ntxiv cov cuab yeej rau Tsev Pabcuam
Txij li thaum txhua yam ua haujlwm raws li qhov xav tau, kuv tau mus rau nruab ESPHome rau kuv lub Tsev Pabcuam teeb tsa thiab kuv tau siv nws los tsim ib lub cuab yeej tshiab thiab xa cov firmware muab rau NodeMCU. Kuv muaj qee qhov teeb meem siv lub web upload los ntawm ESPHome mus tshauv cov firmware muab tab sis thaum kawg, kuv downloaded ESPHome Flasher thiab kuv muaj peev xwm upload lub firmware siv qhov ntawd.
Thaum thawj firmware tau ntxiv rau lub cuab yeej, kuv hloov kho .yamlle rau nws ntxiv rau DHT22 tuav ntu thiab rov rub tawm cov firmware, tam sim no siv qhov hloov tshiab tshaj huab cua los ntawm ESPHome.
Qhov no mus yam tsis muaj kev cuam tshuam thiab sai li sai tau thaum nws ua tiav, cov cuab yeej tau pom qhov ntsuas kub thiab av noo nyob hauv dashboard.
Kauj Ruam 5: Ua ib qho chaw ruaj khov
Kuv xav kom lub xov tooj no tau nruab ib sab ntawm kuv qhov ntsuas kub tam sim no uas kuv muaj hauv kuv lub tsev rau lub qhov cub pellet yog li kuv siv lub thawv hluav taws xob los ua ib lub qhov rooj. Lub DHT22 sensor yog mounted nyob rau hauv ib lub qhov ua nyob rau hauv lub hluav taws xob lub thawv yog li nws muaj peev xwm saib xyuas tej yam kev mob nyob rau hauv lub sab nraud ntawm lub thawv thiab tsis muaj kev cuam tshuam los ntawm tej tshav kub los ntawm lub hwj chim mov.
Txhawm rau tiv thaiv kom tsis txhob muaj cua sov hauv lub thawv, kuv kuj tau ua ob lub qhov rau hauv qab thiab sab saum toj ntawm lub thawv hluav taws xob kom huab cua tuaj yeem dhau los ntawm nws thiab tso tawm cov cua sov.
Kauj Ruam 6: Mount hauv Kuv Chav Nyob
Txhawm rau txhim kho lub thawv hluav taws xob, kuv siv daim kab xev ob sab los lo lub thawv rau ntawm phab ntsa thiab lub ntsuas kub ntawm ib sab ntawm nws.
Txog tam sim no, qhov no tsuas yog kev sim thiab kuv yuav txiav txim siab tias kuv xav hloov qhov chaw no yog li kuv tsis xav ua qhov tshiab ntawm phab ntsa.
Kauj Ruam 7: Kauj Ruam Tom Ntej
Yog tias txhua yam ua tau zoo, kuv tuaj yeem hloov kho qhov project no los ua qhov ntsuas kub rau kuv lub qhov cub pellet kom kuv tuaj yeem tso tag nrho cov lag luam. Txhua yam nyob ntawm seb Tus Pabcuam Hauv Tsev yuav ua haujlwm li cas rau kuv hauv lub sijhawm ntev tab sis peb yuav tau tos kom pom qhov ntawd.
Lub sijhawm no, yog tias koj nyiam qhov project no, nco ntsoov xyuas kuv lwm tus ntawm Instructables nrog rau kuv channel YouTube. Kuv muaj ntau tus tuaj hauv no thov pab nias subscribe thiab.
