Hauv cov lus qhia no kuv siv kev hloov pauv ntab thiab arduino ua ke nrog LORA tranceiver kom xa qhov hloov tshiab thaum cov dej tau nce mus txog qib ib yam. Lub node no siv tsawg heev tam sim no thiab tuaj yeem siv tau ntev heev ntawm cov nyiaj npib ntawm tes.
Kauj Ruam 1: Tau Txais Qhov Xav Tau
Qhov:
- ntab hloov
- arduino pro mini 3.3v 8mhz
- esp zog
- xwm rf95
- xaim rau lub kav hlau txais xov thiab kev sib txuas (Kuv siv 0.8 hli cov tub ntxhais hlau)
- txiv neej rau txiv neej jumper cables
- poj niam rau poj niam jumper cables
- daim ntawv qhia zaub mov
- NPE 2102
- ntsia hlau davhlau ya nyob twg
Cov Cuab Yeej:
- cam khwb cia hlau
- sab txiav
- hlau stripper
- tiaj tus ntswj ntsia hlau
Kauj Ruam 2: Ua Tus Kav hlau txais xov
Rau tus kav hlau txais xov Kuv siv qee qhov txuas txuas ntawm kuv 2x2x0.8mm lossis 2x2 20awg tsheb npav cable. Ntawm cov khoom network koj tuaj yeem xaiv koj li tranceiver thiab kav hlau txais xov zaus hauv ib lub tebchaws.
- 868mhz 3.25 nti lossis 8.2 cm (qhov no yog qhov kuv siv)
- 915mhz 3 nti lossis 7.8 cm
- 433mhz 3 nti lossis 16.5cm
Kauj Ruam 3: Soldering Esp Shield
- Tshem cov resistors ntawm daim thaiv esp (saib R1 txog R3 hauv daim teb liab)
- Muab cov rfm95 nti tso rau ntawm daim thaiv esp.
- Muab cov pinheaders tso rau ntawm daim thaiv esp
- Muab cov kav hlau txais xov txuas rau ntawm daim thaiv esp. Tsis txhob siv yam tsis muaj lub kav hlau txais xov koj tuaj yeem ua rau daim thaiv puas tsuaj.
- Yog tias tus pinheaders tsis tau txuas rau ntawm arduino solder cov no ib yam
Kauj ruam 4: Kev thaiv kab
Hauv daim duab saum toj no koj pom cov kab hluav taws xob.
Kauj ruam 5: Coding
Kuv tau suav nrog 2 cov ntawv. Ib qho yog tus lej tsis muaj LORA tranceiver thiab qhov thib ob Yog tus xa cov ntaub ntawv ntawm LORA.
Kauj Ruam 6: Xaus
Hauv cov lus qhia no koj tau kawm paub yuav siv lub ntab hloov nrog cuam tshuam li cas thiaj li xa xov mus rau LORA server. Txoj hauv kev no koj tuaj yeem ua piv txwv piv txwv li sms xov lossis koj tuaj yeem tsav lub twj tso kua mis kom rov ua dua los ntawm piv txwv ib lub thawv IBC.
