Los ntawm ElectropeakElectroPeak Lub Vev Xaib Ua Haujlwm Ntxiv Ntxiv los ntawm tus sau:

Txog: ElectroPeak yog koj qhov chaw ib-nres los kawm cov khoom siv hluav taws xob thiab coj koj lub tswv yim mus rau qhov tseeb. Peb muab cov lus qhia saum toj kawg nkaus los qhia koj li cas koj tuaj yeem ua koj cov phiaj xwm. Peb kuj tseem muab cov khoom lag luam zoo yog li koj muaj … Ntau Ntxiv Txog Electropeak »

Koj tuaj yeem nyeem qhov no thiab lwm yam kev qhia zoo kawg ntawm

ElectroPeak lub vev xaib raug cai

Txheej txheem cej luam

Tam sim no, kev kawm paub txog IoT cov cuab yeej ua haujlwm thiab siv yog qhov tseem ceeb vim yog kev siv IoT cov txheej txheem ntau ntxiv. Hauv qhov kev qhia no, peb yuav ua kom cov ntiv tes tuaj koom nrog cov khoom siv nrog Arduino, uas ntxiv rau khaws cia cov ntaub ntawv nkag mus thiab cov sijhawm ua haujlwm ntawm daim npav nco, xa cov ntaub ntawv no rau ntawm Thingspeak platform sai li sai tau nws txuas nrog Is Taws Nem thiab Koj tuaj yeem rub cov ntaub ntawv no los ntawm lub vaj huam sib luag hauv ntau hom ntawv, xws li CSV.

Yam Koj Yuav Kawm

• Taw qhia rau Thingspeak
• Kev xa cov ntaub ntawv ntawm Thingspeak siv Nodemcu
• Ua ib qho khoom siv tuaj koom nrog lub ntsuas ntiv tes thiab Arduino

Kauj Ruam 1: Dab Tsi Yog Dab Tsi?

Iot (Internet ntawm yam) yog lub platform uas muaj ntau yam txuas nrog Is Taws Nem, cuam tshuam nrog tib neeg thiab lwm yam khoom siv, thiab feem ntau, tso cov ntaub ntawv ntawm huab xam rau kev tshuaj xyuas.

Thingspeak yog IoT platform uas tso cai rau koj tso saib thiab khaws cov ntaub ntawv nyob hauv huab suav.

Kauj ruam 2: cuam tshuam nrog Thingspeak thiab xa cov ntaub ntawv

Ua raws cov theem hauv qab no kom pib qhov kev sib txuas Thingspeak:

Kauj Ruam 1) Nkag mus rau Thingspeak.com lub vev xaib thiab tsim tus account.

Kauj Ruam 2) Nkag mus tom qab qhib koj tus lej nyiaj thiab nyem rau New Channel hauv My Channel ntu.

Kauj Ruam 3) Hauv lub qhov rai tshiab qhib rau koj, sau lub npe rau koj lub vaj huam sib luag thiab cov lus piav qhia yog tias tsim nyog. Txiav txim siab tus lej uas koj xav tau los ntawm kev muab lawv lub npe. Qhov seem yog xaiv tau. Txuag lub vaj huam sib luag tom qab ua tiav cov ntaub ntawv.

Kauj Ruam 4) Tam sim no mus rau API Keys hauv koj lub vaj huam sib luag.

Kauj Ruam 5) Koj xav tau Channel ID thiab Sau API Key kom xa cov ntaub ntawv, yog li sau lawv.

Kauj Ruam 6) Rub lub Tsev qiv ntawv Thingspeak thiab ntxiv rau koj li Arduino IDE.

Lub tsev qiv ntawv Thingspeak

Kauj Ruam 7) Mus rau Arduino IDE. Qhib WriteMultipleFiels los ntawm ib feem piv txwv thiab nkag mus rau SSID, Lo lus zais, Channel ID, thiab Sau API Qhov tseem ceeb.

Tom qab xa cov cai, koj yuav pom qee tus lej tsis raug tso tawm hauv thaj tsam 1 txog 4 ntawm koj lub vaj huam sib luag. Tib txoj cai teeb tsa tau siv hauv qhov kev tuaj koom rau kev xa cov ntaub ntawv.

Nco tseg

Tos tsawg kawg 15 vib nas this nruab nrab ntawm txhua lub sijhawm koj tso cov ntaub ntawv ntawm Cov Khoom Vaj Huam Sib Luag.

Kauj Ruam 4: Tsim Kev Tuaj Koom Nrog Kev Siv Fingerprint Sensor thiab Arduino

Hauv kab ke no, tom qab sau npe nkag thiab tawm ntawm ib tus neeg los ntawm nws tus ntiv tes, cov ntaub ntawv suav nrog hnub tim, npe, sijhawm tuaj txog, lub sijhawm tawm mus thiab cov sijhawm ua haujlwm rau tus neeg ua haujlwm tau muab khaws cia rau hauv daim npav SD. Tom qab ntawv cov ntaub ntawv no yuav raug xa mus rau Thingspeak thaum lub sijhawm koj tau teev tseg. Thaum tsis muaj kev sib txuas hauv Is Taws Nem, cov ntaub ntawv tsis tau tshaj tawm tau khaws cia thiab yuav xa mus rau Thingspeak sai li sai tau thaum nws txuas nrog Is Taws Nem. Txij li cov ntaub ntawv khaws cia hauv EEPROM ntawm lub microcontroller, lawv yuav tsis ploj thaum muaj lub hwj chim tsis txaus.

Kauj ruam 5: Circuit Court

Tom qab txuas tag nrho cov qauv, muab daim iav LCD tso rau ntawm Arduino.

Tswv yim Txij li LCD Shield npog qee qhov ntawm Arduino pins, koj tuaj yeem ciam hlau rau tus pin tshwj xeeb los ntawm hauv qab ntawm pawg thawj coj saib, yog tias koj xav tau tus pin no.

Kauj ruam 6: Code

Koj xav tau cov tsev qiv ntawv hauv qab no rau cov cai no:

Adafruit-Fingerprint-Sensor-Library

Adafruit-GFX-Lub Tsev Qiv Ntawv

MCUFRIEND_kbv

RTClib

Tam sim no rub tawm cov cai hauv qab no thiab xa nws mus rau koj Arduino. Txoj cai no tau sau rau 11 tus neeg nrog lub npe tsis raug, tab sis koj tuaj yeem hloov lawv thiab tshem nws tawm ntawm lub neej ntawd. Txhawm rau sau npe tshiab, yooj yim txuas lub cuab yeej rau koj lub khoos phis tawj thiab nias tus yuam sij kom nkag mus rau hom sau npe, tom qab ntawd qhib Serial Monitor thiab ua raws cov txheej txheem sau npe raws li tau qhia hauv Serial Monitor.

Download tau cov cai los saum toj no:

Koj tuaj yeem kawm paub ntau ntxiv txog kev siv daim npav SD, lub moos moos, thiab LCD hauv cov kab txuas hauv qab no:

SD Card Module w/ Arduino: Yuav Ua Li Cas Nyeem/ Sau Cov Ntaub Ntawv

Yuav Ua Li Cas Siv DS1307 RTC Module nrog Arduino & Ua Kev Nco

Tsis Pib Pib Phau Ntawv Qhia rau TFT LCD Qhia los ntawm Arduino.

Nodemcu ua tiav txoj haujlwm xa cov ntaub ntawv hauv cov kab ke no. Nws yuav siv cov ntaub ntawv xa tawm los ntawm Arduino los ntawm qhov chaw nres nkoj txuas thiab xa cov xwm txheej ntawm kev xa mus rau Arduino. Tshaj tawm cov cai hauv qab no ntawm koj Nodemcu.

Ua ntej, hloov Channel ID thiab Sau API Key raws li koj Cov Khoom Vaj Huam Sib Luag.

Txoj hlua_Analuze (); ua haujlwm hauv txoj cai no faib Nodemcu cov hlua nkag mus rau hnub, npe, tuaj txog thiab tawm sijhawm, thiab sijhawm ua haujlwm, thiab xa cov ntaub ntawv no mus rau Thingspeak. Tom qab ntawd yog tias txheej txheem uploading ua tiav, nws xa tus cim "1", thiab txwv tsis pub nws xa tus cim "0" mus rau Arduino.

Kauj Ruam 7: Sib Sau Cov Ntaus Tuaj

Koj tuaj yeem siv cov duab qhia hauv qab no thiab Plexiglass nrog cov xim sib txawv lossis lwm yam khoom siv los tsim lub cev ntawm cov cuab yeej tuaj koom.

Rub tawm lub cuab yeej lub cev laser txiav daim ntawv qhia los ntawm saum toj no:

Tom qab tso cov khoom siv hluav taws xob thiab sib dhos tag nrho lub cev, teeb tsa nws hauv qhov chaw xav tau. Tam sim no, tsuas yog ntsaws 12V adapter rau lub cuab yeej thiab nws pib ua haujlwm.

Kauj Ruam 8: Dab Tsi Ntxiv?

• Sim siv ntau lub cim ntawm LCD.
• Sim ntxiv qhov kev xaiv RFID rau hauv kab ke.
• Sim muab cov ntaub ntawv tso rau hauv google spreadsheets es tsis txhob siv Thingspeak.

Yog tias koj pom cov ntawv qhia no muaj txiaj ntsig thiab txaus siab thov nyiam peb hauv facebook.
