ESP8266 module muaj onboard WiFi. Txij li cov mesh txoj cai (PAINMesh) peb tab tom siv los tsim Kev Nkag Mus Rau ntawm txhua tus qauv, thaj tsam rau ib puag ncig thoob plaws kev mus cuag yog qhov tseem ceeb. Kuv siv cov khoom qab zib pas nrig, thiab muab CPU tso rau saum toj kom tau txais qhov zoo tshaj plaws, thiab nws yog li 50-100 ko taw - ib mev lossis ob hauv kuv lub zej zog. Qib siab thiab zoo dua kab pom (LOS) txhim kho yam. Qhov ntau tau hla txoj kev hauv qee kis (vam khom ntau lub tsheb thaiv LOSSIS).
Muaj ob peb lub tsev uas tsis tau sib txuas vim muaj WiFi cuam tshuam, tab sis cov teeb pom kev zoo txawm tias thaum tsis sib txuas. Kuv tau ua "rov ua dua" ntawm qhov tsuas yog D1 Mini ntawm tus pas uas siv los ntawm USB roj teeb. Thaum muab tso nruab nrab ntawm cov tsev, lawv tau sib dhos kom raug. Rau qhov rov ua dua tej thaj chaw deb koj tuaj yeem siv tau lub hnub ci USB roj teeb, txawm hais tias lawv tsis tau them ceev heev.
Kuv tseem pom cov teeb meem sib txuas sib txuas tsis tu ncua, tom qab ntawd pom cov ntawv no ntawm muaj ntau lub hauv paus lossis ua rau lawv nthuav tawm:
gitlab.com/p stainlessMesh/pitnessMesh/-/wik…
Siv qhov teeb tsa ntawd, nws pib ua haujlwm zoo dua! Qhov no txheeb xyuas ib qho tshwj xeeb ntawm qhov tseem ceeb, yog li kuv cov cai los tham txog kev tswj hwm ntawm qhov tsis muaj qhov xav tau, uas tuaj yeem faib cov mesh. Kuv tau txuas qhov hloov tshiab/hloov pauv tus lej piv txwv. Txoj hauv kev no xav kom lub hauv paus tseem ceeb nyob rau lawv kom ua tiav, yog li cov mesh tsis yog qhov ua txhaum cai, tab sis ua haujlwm tau zoo dua thaum kis tawm raws li kuv li. Nco ntsoov hloov kho cov cai rau cov ntawv ntawd - tsuas yog ib lub hauv paus yuav tsum tau teeb tsa rau hauv paus - saib cov lus hauv kab lus.
Kuv kuj tau ntxiv ib qho hloov tshiab rau SetRoot qhov sib txawv: Kuv ntxiv cov cai rov pib dua ESP8266 yog tias tsis muaj lus txib rau 10 feeb. Qhov no muab txoj hauv kev rau rov tshawb pom lub hauv paus node. Qhov no zoo li pab nrog qee qhov ntawm cov nyob deb dua.
Thaum kawg ntawm lub caij, kuv muaj peev xwm sim qee qhov D1 Mini Pro modules. Lawv muaj lub kav hlau txais xov ceramic ntawm lub rooj tsavxwm, thiab koj tseem tuaj yeem siv U.
