Hauv lub sijhawm no peb yuav ua tus yam ntxwv luv luv txog LoRa ™ thiab tshwj xeeb tshaj yog Xov Tooj Cua RFM95/96 tsim los ntawm Hoperf Electronics. Txij li ob peb lub hlis dhau los, 2 tus qauv tuaj txog, thaum xub thawj kuv xav hais qhia txog cov ncauj lus uas tau tos ntev.

Lub Vev Xaib: Hoperf Electronics

Tus kheej rau lub sijhawm ntev Kuv xav ua qhov kev sim nrog LoRa, raws li kev qhia hauv Internet Ntawm Yam (IoT) Siv NiceRf LoRa1276 ntawm kiag liautomation.com, peb yuav tham me ntsis txog LPWAN tes hauj lwm (Tsawg Lub Hwjchim Loj Thoob Ntiaj Teb Network) lawv tso cai rau lub zog qis. kev siv nyob hauv thaj tsam kev pab dav, tseem hu ua nrug deb.

Peb xub piav qhia meej tias LoRa thiab LoRaWAN tsis zoo ib yam:

  • LoRa yog txheej txheej ntawm lub cev lossis hauv cov lus yooj yooj yim yog kev hloov pauv, lub modem lossis xov tooj cua, kho vajtse.
  • LoRaWAN yog lub network raws tu qauv lossis architecture uas ua haujlwm ntawm LoRa.

LoRa yog dab tsi?

LoRa ™ yog xov tooj cua thev naus laus zis ntev "Lo ng- Ra nge" nws lub ntsiab lus tseem ceeb:

  1. Nws qhov kev hloov pauv ntawm cov spectrum tso cai rau muaj txiaj ntsig ntau dua rau lwm cov thev naus laus zis.
  2. Kev nkag siab siab (-168dB) ua ke nrog kev tiv thaiv siab rau cuam tshuam.
  3. Kev Siv Tsawg (txog 10 xyoo nrog roj teeb, zoo nyob ntawm qee yam ntxwv).
  4. Hloov cov ntaub ntawv qis (txog 255 bytes).

Kauj Ruam 2: Qauv RFM95 ntawm Hoperf Electronics

Kuv tau xaiv Xov Tooj Cua-Modem RFM95 los ntawm Hoperf cov khoom siv hluav taws xob, txij li kuv pom tias twb tau koom ua ke nrog cov txheej txheem twb tau siv xws li Arduino, ESP8266, Raspberry pi thiab kuv xav tias nrog ESP32, lawv yeej nrov heev.

Hauv kev ua lag luam muaj ntau yam ntawm cov qauv, txhawm rau xaiv qhov raug coj mus rau hauv tus account qhov zaus ntawm thaj chaw uas lawv nyob, hauv kuv qhov xwm txheej hauv Colombia (South America) ISM yog 915.0 MHz.

RF95 tus qauv yog rau 915.0 MHz, lub Hoobkas cim rau sab nraum qab ntawm pcb

  • CEEB TOOM: Ua haujlwm voltage 3.3V Pom zoo, MIN 1.8V - MAX 3.7V, tuaj yeem txuas ncaj qha rau ESP8266 thiab arduino micro pro rau 3.3v, rau lwm lub platform rau 5v siv cov hloov hluav taws xob.
  • Kev teeb tsa thiab kev sib txuas lus ntawm tus qauv yog ua tiav ntawm 4-xaim SPI Bus, thev naus laus zis tau siv hauv txhua lub microcontrollers.
  • Nws muaj 6 Gpio teeb tsa tau los ntawm software, feem ntau cuam tshuam cuam tshuam nrog kev ua haujlwm ntawm RFM95.
  • Txawm hais tias nws tuaj yeem teeb tsa ua LoRa TM modem, nws tseem tuaj yeem teeb tsa ua FSK / OOK modem thiab GFSK, MSK thiab GMSK cov qauv.

  • 2 Module - Xov tooj cua RFM95 aliexpress
  • 2 dawb PCB adapters rau ESP8266 12E/F.

Nco tseg: Txhawm rau ntsuas nws tau pom zoo kom muaj 2 lub xov tooj cua RFM95, ib qho tsuas yog tsis ua haujlwm.

Kauj Ruam 5: Cov Lus Xeem & Ua tiav Tutorial

Cov lus xaus

Koj tuaj yeem hais tias LoRa yog "Koj xa ob peb cov ntaub ntawv tab sis lawv yuav mus ntxiv …".

Cov thev naus laus zis no muaj cov ntawv thov zoo hauv kev nyeem ntawv ntsuas / ntsuas rau xa cov ntaub ntawv hla kev deb.

Koj tuaj yeem hais tias LoRa cov xov tooj cua tuaj ntawm lub Hoobkas nrog cov zaus lossis band tau hais tseg ua ntej hauv kuv rooj plaub 915MHz, Muaj qee lub xov tooj cua uas tso cai ua haujlwm hauv txhua pawg, txij li lub nti tuaj yeem hloov pauv tab sis RC lim tawm cov kav hlau txais xov qhov tsis zoo muab rau lawv tias yog qhov tseem ceeb.

Qhov siab tshaj plaws nyob deb ua rau kuv xav paub vim tias lawv nyob hauv yuav luag txhua qhov xwm txheej raws li lub chaw tsim khoom, peb yuav ua qhov kev ntsuas los txheeb xyuas thiab txheeb xyuas qhov deb tshaj plaws thiab kev siv hluav taws xob ntawm RFM95 module.

Hauv Kev Qhia Ntxiv tom ntej no peb yuav ua LoRa kev sib txuas lus nrog Esp8266 thiab / lossis Arduino, tom qab ntawd peb yuav sim nrog LoRaWAN thiab Cov Yam Network platform.
