Code ya Arduino mpo na kosalela senseur ya Hall NJK-5002C

Libosoli

Mokanda oyo emonisi ndenge ya kosala sistemɛ ya koyoka mbala ya mazíto na kosalela senseur ya NJK-5002C Hall effect mpe Arduino. Projɛ oyo emonisi ndenge ya kosalela mbala ya mazíto mpo na kopelisa relay, oyo ekokamba na yango kofungola mpe kokanga AC load, lokola ampoule to fan. Oyo ezali ndenge ya malamu mpe ya libateli mpo na kosala automatisation ya biloko oyo esalelaka AC na kosalela signal ya contrôle ya voltage moke.

Mokano ya liboso ezali ete senseur ya Hall emonaka ete mbala ya mazíto ezali. Ntango mbala ya mazíto (mingi mingi, pole ya Sudi) ekomi pene ya senseur, yango ebimisaka signal ya moke. Arduino atangaka signal oyo mpe apelisaka module ya relay. Relay esalaka lokola commutateur, ekangaka to efungolaka AC power mpo na charge na yo. Mbulamatari oyo ezali moboko ya ntina mpo na misala mingi ya automatisation.

Tala makanisi mosusu ya misala oyo okoki kosala na teknoloji oyo:

• Bongengi ya Automatique: Pelisa mwinda ntango porte to fenêtre oyo ezali na mbala ya mazíto efungwami.
• Alarme ya Libateli: Pelisa alarme to mwinda ntango contact ya mazíto ebukani.
• Kotanga na Ligne ya Production: Tanga biloko na conveyor belt ntango eleki pene ya senseur oyo ezali na mbala ya mazíto.
• Komonisa Esika: Monisa esika ya loboko ya robot to eteni ya masini oyo ezali na mbala ya mazíto.
• Libateli ya Sécurité: Katisa power ya masini ntango garde ya sécurité efungwami.

Biloko ya Hardware oyo Esengeli

• Arduino Uno (to carte mosusu oyo ekokani)
• Senseur ya NJK-5002C Hall Effect
• Module ya Relay (5V)
• Charge ya AC (lokola ampoule to fan moke)
• Corde ya Power mpo na Charge ya AC
• Bafilo ya Jumper
• Mbala ya mazíto (oyo ezali na pole ya Sudi oyo emonani malamu)

Mokambi ya Bokolisa Bafilo

Kokangisa bafilo mpo na projɛ oyo ezali pete. Senseur mpe module ya relay nyonso mibale ezali kozwa power na ba pins ya 5V mpe GND ya Arduino. Signal oyo euti na senseur etangamaka na pin ya entrée ya numérique, mpe relay ekolamelaka na pin ya sortie ya numérique.

Tala ndenge ya kokangisa bafilo:

• Senseur ya NJK-5002C:
  • Fil ya Brown → Arduino 5V
  • Fil ya Bleu → Arduino GND
  • Fil ya Noir → Arduino Digital Pin 2
• Module ya Relay:
  • Pin ya VCC → Arduino 5V
  • Pin ya GND → Arduino GND
  • Pin ya IN (to Signal) → Arduino Digital Pin 8
• Charge ya AC:
  • Kata filoko moko ya corde ya power ya charge ya AC na yo.
  • Kangisa suka moko ya filoko oyo ekatami na terminal ya Normally Open (NO) ya relay.
  • Kangisa suka mosusu ya filoko oyo ekatami na terminal ya Common (COM) ya relay.

(na vidéo na 05:09) Diagramme oyo ezali na nse emonisi bokolisa oyo. Yeba ete relay ezali ya ndenge ya low-trigger, elingi koloba ete epelisamaka ntango pin ya signal ekomi na LOW.

Limonisi ya Code

Code ya Arduino mpo na projɛ oyo ezali pete mpe ezali kolandela kotanga senseur mpe kokamba relay. Biteni ya ntina ya code oyo okoki kobongola ezali na likolo ya sketch.

#define sensorPin  2 // pin 2 
#define relayPin 8 // pin

const int wait = 3000;// after switched ON, wait for this amount of time

• #define sensorPin 2: Oyo efinir pin ya numérique ya Arduino oyo ekangisami na fil ya noir ya senseur ya Hall. Okoki kobongola yango na pin mosusu ya numérique oyo ezali.
• #define relayPin 8: Oyo efinir pin ya numérique ya Arduino oyo ekangisami na pin ya IN na module ya relay. Okoki kobongola yango na pin mosusu ya numérique oyo ezali.
• const int wait = 3000;: Oyo ezali variable ya ntina mingi. Etyaka ntango na millisecondes oyo relay ekotikala na ON nsima ya koyoka mbala ya mazíto. Na vidéo, ekomami na 3000 ms (secondes 3). Soki olingi ete relay ekufa mbala moko ntango mbala ya mazíto elongolami, tia yango na 0. (na vidéo na 08:15)

Code esalelaka mpe delay(300) na suka ya boucle ya liboso. Oyo ezali debounce delay mpo na kopekisa bofungoli mpe bokangoli ya mbala moko oyo esengeli te. Okoki kobongola valeur oyo, kasi mise en place ya 100 ms to 300 ms ezali malamu mpo na fonctionnement ya makasi. (na vidéo na 11:03)

Limonisi ya Projɛ ya Moi

Na démonstration ya vidéo, siystemɛ emonami ete ezali kosala na ampoule ya AC. Ntango pole ya Sudi ya mbala ya mazíto ekomi pene ya senseur, LED ya senseur epelaka, Arduino atangaka signal ya LOW, mpe epelisaka relay. Oyo ekangisaka AC power na ampoule, mpe epelisaka yango. Moniteur ya série mpe ekomaka "Sensed".

(na vidéo na 11:19) Ezali malamu koloba ete senseur ezali na polarité. Ekopelaka kaka na Pole ya Sudi ya mbala ya mazíto. Pole ya Nord ekoyokama te. Lisusu, mbala ya mazíto esengeli kozala pene mpe esengeli kolandana malamu na elongi ya senseur mpo ete eyokama malamu. Démonstration emonisi ete senseur esalaka te soki ezali na ngambo to na mosika.
