Tswj thiab siv koj lub cuab yeej siv hluav taws xob los ntawm kev deb (Kilometers) yam tsis muaj internet. Qhov no ua tau los ntawm LoRa!
Hav, ua li cas, cov menyuam? Akarsh nov los ntawm CETech.
Cov PCB no tseem muaj cov zaub OLED thiab 3 qhov txuas uas txuas nrog ESP32. Koj tuaj yeem ua dab tsi nrog txoj cai thiab tswj kev xa xov siv LoRa/WiFi/Bluetooth. Yog li, luv luv, txoj haujlwm no muaj ESP32 uas tuaj yeem muab WiFi/Bluetooth ua haujlwm, LoRa module, OLED zaub thiab 3 qhov xa tawm. Muaj peev xwm nrog txoj cai tsis muaj qhov kawg. Kuv kuj tau ntxiv thaj chaw tiv thaiv qhov chaw uas koj tuaj yeem ntxiv cov ntsuas lossis txuas ntxiv mus rau ESP32 uas tseem tuaj yeem nkag tau.
Nov yog hom ntawm ntu 2 ntawm qhov haujlwm. Yog li rau txhua qhov kev tswj hwm zoo li qhov no koj xav tau chaw taws teeb los tswj cov khoom.
Kuv tau ua LoRa raws cov chaw taws teeb uas koj tuaj yeem tshawb xyuas ntawm no:
Hauv kuv qhov xwm txheej, kuv siv cov chaw taws teeb thiab tus tswj hwm no ua ke thiab lawv ua haujlwm zoo li ntxim nyiam!
Kauj Ruam 1: Qhov Chaw
Thawj zaug ua qhov tseem ceeb, Kuv siv ESP32 tus qauv los ntawm DFRobot. Txuas nws ntawm PCB siv qee tus txiv neej thiab poj niam lub taub hau. Kuv siv OLED zaub.
Rau LoRa lub hom phiaj, Kuv siv RYLR896. Kuv hais qhia qhov qauv no vim nws yooj yim heev rau siv dua UART siv AT cov lus txib.
Koj tuaj yeem pom cov ntu hauv qab no:
1) ESP32 FireBeetle Module:
2) Reyax RYLR896 LoRa module:
3) Kuv tus PCB tsim: Kuv tau suav nrog Gerber cov ntawv hauv qab no.
Rau ob ntu kawg yog tias koj muaj teeb meem nrhiav lawv tawm koj tuaj yeem xa xov/email rau kuv thiab ib qho twg kuv tuaj yeem pab koj pom nws hauv koj thaj chaw lossis kuv tuaj yeem xa lawv mus rau koj yog tias koj xav tau.
Kauj Ruam 2: Tau PCBs rau Koj Txoj Haujlwm Tsim
Koj yuav tsum txheeb xyuas JLCPCB rau xaj PCBs online kom pheej yig!
Koj tau txais 10 qhov zoo PCBs tsim thiab xa mus rau koj lub qhov rooj rau 2 $ thiab qee qhov xa khoom. Koj tseem yuav tau txais luv nqi ntawm kev xa khoom ntawm koj thawj daim ntawv xaj. Txhawm rau tsim koj tus kheej PCB lub taub hau kom yooj yim EDA, ib zaug uas ua tiav xa koj cov ntaub ntawv Gerber mus rau JLCPCB kom tau txais lawv tsim nrog qhov ua tau zoo thiab lub sijhawm hloov pauv sai.
Kauj Ruam 3: Nkag Siab Txog Reyax Module thiab Yuav Siv Nws Li Cas. (TSIS MUAJ: Koj tuaj yeem hla Kev Nyeem Cov Kauj Ruam no Yog Tsis Txaus Siab Rau Kev Ua Haujlwm)
1. LoRa module peb muaj yog UART module uas tau teeb tsa siv AT cov lus txib.
2. Tus qauv tsev muaj STM32 MCU uas ua txhua yam tham nrog SPI LoRa module onboard RYLR896.
3. Cov lus txib hauv daim duab yog cov hauv paus uas koj tuaj yeem xa mus rau daim ntawv no rau ntau ntxiv: REYAX-Lora-AT-COMMAND-GUIDE
4. Kuv tseem pom zoo kom koj hla kuv tus YouTube video uas kuv piav qhov no kom raug.
Kauj Ruam 4: Kev sib txuas ntawm Cov Qauv hauv PCB
1. Ob qho qauv yuav txuas nrog tib yam li hauv daim duab saum toj no.
2. Thaum ob qho qauv txuas nrog, koj tuaj yeem tsim cov qauv ib los ntawm ib qho thiab tom qab ntawd sim ua qhov haujlwm.
3. Koj yuav tsum txuas lub transistor Circuit ntau zaus rau ntau qhov txuas koj txuas.
Txhua qhov kev sib txuas uas tau hais los saum toj no tau ua tiav hauv PCB thiab yog li tsis tas yuav muaj lwm txoj hlua.
Kauj Ruam 5: Soldering ntawm PCB
Muab tag nrho cov khoom siv rau PCB.
Kuv xav hais kom muab cov khoom sib xyaw qhov siab qis ntawm PCB ua ntej thiab tom qab ntawd txav mus rau cov khoom siv nrog qhov siab ntau dua li lub taub hau thiab lwm yam.
Ua ntej lub zog ntsuas qhov ntsuas ntsuas txhua qhov kev sib txuas siv lub ntsuas cua rau qhov tsis zoo ntawm cov pob qij txha txuas thiab luv Circuit Court.
Txhawm rau teeb tsa tus qauv koj tuaj yeem txuas tus qauv esp32 ncaj qha rau koj lub PC siv USB cable.
Kauj Ruam 6: Rub tawm thiab teeb tsa Arduino IDE
Rub tawm Arduino IDE los ntawm no.
1. Nruab Arduino IDE thiab qhib nws.
2. Mus rau File> Preferences
3. Ntxiv https://arduino.esp8266.com/versions/2.5.0/package_esp8266com_index.json Tus Thawj Saib Xyuas Ntxiv URLs.

5. Tshawb nrhiav ESP8266 thiab tom qab ntawd teeb tsa lub rooj tsavxwm.
6. Rov pib dua IDE.
Kauj Ruam 7: Coding Txoj Haujlwm
Rub tawm GitHub chaw cia khoom:
2. Rub tawm lub chaw cia khoom rub tawm.
3. Luam cov tsev qiv ntawv los ntawm cov chaw khaws cia rub mus rau Lub Tsev Qiv Ntawv nplaub tshev hauv Arduino daim duab kos.
4. Qhib Transmitter kos duab hauv Arduino IDE.
5. Mus rau Cov Cuab Yeej> Pawg Thawj Coj. Xaiv lub rooj tsav xwm uas tsim nyog uas koj siv, Firebeetle ESP32 hauv kuv rooj plaub.
6. Xaiv qhov ua kom raug. chaw nres nkoj los ntawm kev mus rau Cov Cuab Yeej> Chaw Nres Nkoj.
7. Ntaus lub pob upload.
8. Thaum lub tab hais tias Ua tiav Kev Tshaj Tawm koj yuav tsum rov ua cov kauj ruam saum toj no nrog tus txais tus qauv kom tso cov cai.
Kauj Ruam 8: Ua Si Nrog Tus Ntaus
1. Tsuas yog qhib lub cuab yeej rau, koj tuaj yeem tsoo cov nyees khawm sib txawv ntawm cov chaw taws teeb kom pom qhov nyem nyem.
2. Txhawm rau ua kom lub cuab yeej no ua haujlwm koj yuav tsum muaj LoRa raws cov chaw taws teeb, koj tuaj yeem pom qhov uas kuv tau tsim nyob ntawm no:
3. NCO! lub cuab yeej ua haujlwm raws li qhov xav tau.
