Nyob zoo cov neeg! Hauv Cov Lus Qhia no, peb yuav kawm paub yuav ua li cas cuam tshuam LM35 sensor rau NodeMCU thiab Qhia cov ntaub ntawv ntsuas kub hauv is taws nem ntawm lub xov tooj smartphone nrog Blynk daim ntawv thov.
(Tsis tas li hauv qhov haujlwm no peb yuav siv SuperChart widget hauv Blynk daim ntawv thov kom cov ntaub ntawv khaws cia hauv Blynk huab thiab peb tau pom tag nrho cov ntaub ntawv yav dhau los hauv kab ntawv. Hauv ntej, tsis muaj cov ntaub ntawv sensor poob thiab koj tau pom txias saib daim duab.)
Khoom siv
Pib …
Cov npe khoom xav tau rau txoj haujlwm no
1. NodeMCU
2. LM35
3.jumper xov hlau
4. Txhua daim ntawv
5. Arduino lub tswv yim (nrog blynk tsev qiv ntawv teeb tsa)
Kauj Ruam 1: Kev Sib Txuas Hauv Circuit
LM35 muaj 3 tus pin. (Thaum lub ntsej muag tiaj ntawm lub ntsej muag tau ntsib koj, Cia tus pin1 yog tus pin sab laug, tus pin nruab nrab yuav yog tus pin2 thiab tus pin sab xis yuav yog tus pin 3)
Pin1 txuas nrog 3.3v ntawm NodeMCU.
Pin2 txuas nrog A0. (ib thiab tsuas yog tus pin analog ntawm NodeMCU)
Pin3 txuas nrog hauv av ntawm NodeMCU.
(Kuv yuav tsis siv jumper xov hlau raws li kuv npaj siab ua kom txuas nrog rau qee lub sijhawm)
Kauj Ruam 2: Teeb tsa Daim Ntawv Thov Blynk
1. Nruab Blynk app los ntawm Playstore/ App khw thiab nkag mus rau koj tus as khauj.
2. Tsim txoj haujlwm tshiab los ntawm kev xaiv NodeMCU ua lub cuab yeej thiab Wi-nkaus ua hom txuas. (Tus lej cim yuav raug xa mus rau koj tus lej ID, qhov no yuav siv tom qab hauv tus lej)
3. Nyem + icon thiab ntxiv cov cuab yeej hauv qab no - Cov ntawv cim npe tus nqi, ntsuas thiab ntsuas cua. (hloov cov widgets rau koj nyiam)
4. Peb yuav siv daim ntawv lo tus nqi widget los tso saib lub sijhawm ua haujlwm. (tus naj npawb ntawm vib nas this los ntawm lub sijhawm peb txhawb NodeMCU) Los ntawm kev siv qhov no peb muaj ob peb qhov zoo- peb tuaj yeem paub tias Nodemcu txuas nrog internet lossis (lub txee yuav tsum nce los ntawm 1 txhua ob) thiab lub txee no rov pib dua txhua lub sijhawm rov pib dua lub zog (yog li koj yuav tau txais lub tswv yim ntxhib thaum lub hwj chim tsis tsim nyog).we yuav siv tus pin virtual V6 rau qhov no thiab nyeem tus nqi teev rau 1 thib ob.
5. Peb yuav siv lub ntsuas cua los ntsuas qhov ntsuas kub. cia peb xa cov ntaub ntawv mus rau blynk app los ntawm tus lej virtual V5, cov zaub ntau yuav yog 0 txog 50 degrees Celsius thiab nyeem ntawv teeb tsa rau PUSH (txij li peb yuav siv superchart).
6. Tam sim no los Superchart. Peb yuav siv qhov no los saib qhov ntsuas kub dhau los hauv kab ntawv. Hauv cov txheej txheem widget ntxiv Kub raws li cov ntaub ntawv ntws. los ntawm txhaj rau lub cim teeb tsa nyob ib sab ntawm cov ntaub ntawv tsim kwj, xaiv tus lej pin ua tus pin virtual V5. (Koj tuaj yeem hloov kho qhov chaw uas koj nyiam).
** NCO TSEG: Yog tias koj tsis nkag siab kuv txhais li cas hauv cov theem saum toj no, koj tuaj yeem ua raws cov duab saum toj no los teeb tsa daim ntawv thov.
Kauj ruam 3: Code
Kuv yuav muab cov ntaub ntawv xav tau hauv nplooj ntawv no.
Kauj Ruam 4: Ua tiav…
Tshaj tawm cov cai rau NodeMCU los ntawm kev txuas nws mus rau koj lub PC. nias lub pob ua si hauv Blynk app, los ntawm tam sim no koj yuav tsum tau txais cov ntaub ntawv rau koj lub xov tooj ntawm tes thiab qhov ntawd yog nws koj tuaj yeem tshem nws los ntawm PC thiab txuas nws rau qee lub txhab nyiaj thiab tso tag nrho cov ntsuas kub ntsuas qhov twg los tau.
** NCO TSEG: Ob peb yam yuav pom-
1. UPTIME: Thaum Blynk app txuas rau NodeMCU hauv is taws nem, nws thov ua haujlwm txhua txhua ob. Yog tias lub txee no tsis nce txhua ob, nws tsuas txhais tau tias kev sib txuas network ntawm ob sab xov tooj lossis NodeMCU sab tsis muaj zog lossis tawg (lossis NodeMCU tsis muaj zog).
2. SUPERCHART: Koj tuaj yeem xa koj cov ntaub ntawv kaw tseg cov ntaub ntawv ua CSV cov ntaub ntawv lossis tseem tshem tawm cov ntaub ntawv yav dhau los kom pib tshiab. (qhov ntsuas ntsuas kub yuav tsum tau teeb tsa rau PUSH txhawm rau siv Superchart)
3. Kuv tau ntxiv cov ntawv sau rau ob peb daim duab. (yuav tshem qee qhov ua xyem xyav)
Vam tias koj nyiam qhov kev qhia no!
