LORA Tank Qib Sensor
LORA Tank Qib Sensor

Nov yog kuv qhov LORA thib 6 qhia. Thawj qhov yog LORA tus phooj ywg rau phooj ywg sib txuas lus nrog arduino. Koj tuaj yeem siv lub server server ntawm cov lus qhia no kom tau txais cov ntaub ntawv los ntawm lub ntsuas cua no. Kuv tau ua qhov no vim tias kuv xav tau lub zog siv hluav taws xob tsawg uas ntsuas lub ntsuas dej ntawm kuv lub thoob dej nag. Kuv tsis tau pom dua ib qho cabling yog li kuv xav tau lub roj teeb siv hluav taws xob los xa cov ntaub ntawv. Txij li LORA tsis siv lub zog ntau nws zoo kawg nkaus rau txoj haujlwm no.

Raws li lub sensor kuv siv lub ultrasonic sensor. Qhov ntsuas zoo li no xa lub suab mus rau qhov khoom thiab tom qab ntsuas lub sijhawm kom txog thaum pom lub teeb liab rov qab los.

Vim tias lub ntsuas cua yuav muab tso rau hauv qhov chaw noo kuv xaiv siv cov dej tsis sib haum ntawm HC-SR04 ultrasonic sensor uas yog jsn-sr04t.

Raws li cov ntawv teev tseg, lub ntsuas hluav taws xob no khiav ntawm 3 thiab 5.5v thiab muaj thaj tsam ntawm 20cm thiab 600cm Hauv qhov chaws kuv teeb tsa thaj tsam ntawm 25 thiab 350cm.

Kauj Ruam 1: Xav Tau Qhov

Sensornode:

  • waterproof ultrasonic sensor
  • arduino (Kuv siv cov pro mini)
  • esp breakout board
  • xaim rau tus kav hlau txais xov (Kuv siv 0.8 cov tub ntxhais hlau xaim)
  • rfm95 tranceiver (xaiv qhov yog)
  • qee cov xov hlau jumper

Cov Cuab Yeej:

  • cam khwb cia hlau
  • sab txiav
  • hlau stripper

Kauj ruam 2: Tsim 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

Soldering Esp Shield
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

Thaiv
Thaiv

Kev txuas yog yooj yim heev.

Kauj ruam 5: Coding

Rub tawm cov duab kos thiab siv server node ntawm kuv thawj lora qhia kom tau txais cov ntaub ntawv. Koj tuaj yeem pom cov ntaub ntawv nkag mus rau hauv kab ntawv saib.

Kauj Ruam 6: Xaus

Hauv cov lus qhia no kuv tau ua lub ntsej muag rau ntsuas cov qib dej hauv lub pas dej lossis cov txiv qaub uas ua rau siv LORA. Yog tias koj nyiam qhov no yuav mus thov tawm tswv yim lossis ua rau koj nyiam. Txoj kev no kuv paub yog tias kuv yuav tsum ua txuas ntxiv cov kev qhia no los tsis yog.
