Code ya Arduino mpe Video ya Module ya Senseur ya Hall KY-024

Code ya Arduino mpe Video ya Module ya Senseur ya Hall KY-024

Na boyekoli oyo, tokotalela ndenge ya kosalela module ya senseur ya Hall KY-024 na Arduino mpo na koyeba ba champs ya magnetiki. Senseur ya Hall ekosalelama mpo na kopelisa likambo moko ntango emoni champ ya magnetiki, mpe tokotalisa ba résultats na Serial Monitor. Nsuka ezali ndenge ya pete mpe ya kitoko ya kosangisa boyoki ya magnetiki na ba projets na yo, mpo na kopesa yo moboko mpo na kokola lisusu. Mpo na ba ndimbola ya mingi, tala video (na video na 00:00).

Biloko ya Matériel

Module ya senseur ya Hall esalemi mpo na koyeba ba champs ya magnetiki mpe esalelamaka mingi na ba applications ndenge na ndenge, lokola koyeba bopembeni mpe koyeba vitesse. Ntango champ ya magnetiki ezali, senseur ebimisaka signal oyo Arduino akoki kotanga. Oyo epesaka Arduino boyebi ya ntango oyo eloko moko na champ ya magnetiki ezali pembeni.

Na projet oyo, tokosalela mpe buzzer lokola eloko ya kosala. Ntango senseur ya Hall emoni champ ya magnetiki, Arduino akopelisa buzzer mpo na kopesa makelele ya koyoka. Ba composants ya liboso oyo esangani ezali senseur ya Hall, carte ya Arduino, mpe buzzer.

Ba Détails ya Datasheet

• Kokamba ete alimentation ezali na kati ya intervalle ya tension oyo ekomami.
• Keba na ba limites ya courant ya sortie mpo na koboya kobebisa module.
• Salela résistance ya pull-up soki esengeli mpo na ba lectures ya semba.
• Kotika senseur mosika na ba champs ya électromagnétique makasi oyo ekoki kosala interférence.
• Kobongisa senseur kolanda ba besoins ya application particulier.

Ba Instructions ya Câblage

Mpo na kokangisa module ya senseur ya Hall na Arduino, banda na kokangisa pin ya VCC ya senseur na pin ya 5V ya Arduino mpo na puissance. Na sima, kokangisa pin ya GND na pin ya GND ya Arduino mpo na kokokisa circuit. Pin ya sortie ya senseur ya Hall, oyo mingi ekomami lokola OUT, esengeli kokangama na pin ya digitale 2 na Arduino.

Mpo na buzzer, kokangisa terminal ya positif na pin ya digitale 8 na Arduino, mpe kokangisa terminal ya négatif na GND. Ndenge oyo epesaka Arduino makoki ya kotanga sortie ya senseur mpe kopelisa buzzer ntango champ ya magnetiki emonani.

Ba Exemples ya Code & Explication

Code oyo elandaka ebandisaka senseur ya Hall mpe buzzer. Efinir ba pins mpo na senseur mpe mpo na likambo ya kosala. Boucle ya liboso etangaka état ya senseur mpe epelisaka buzzer kolanda yango.

#define DETECT 2 // pin 2 mpo na senseur
#define ACTION 8 // pin 8 mpo na kosala likambo moko

void setup() {
  Serial.begin(9600);
  pinMode(DETECT, INPUT); // définir pin ya entrée ya détection
  pinMode(ACTION, OUTPUT); // définir pin ya sortie ya ACTION
}

Na code oyo, variable DETECT ekomami na pin 2, oyo esalelamaka mpo na kotanga senseur. Variable ACTION ekomami na pin 8, epai buzzer ekangami. Fonction ya setup ebandisaka communication ya série mpe esengaka ba modes ya pins.

void loop() {
  int detected = digitalRead(DETECT); // tanga senseur ya Hall
  if (detected == LOW) {
    digitalWrite(ACTION, HIGH); // pelisa buzzer
    Serial.println("Detected!");
  } else {
    digitalWrite(ACTION, LOW); // zimisa buzzer
    Serial.println("Nothing");
  }
  delay(200);
}

Eteni oyo ya code etalaka ntango nyonso état ya senseur ya Hall. Soki senseur emoni champ ya magnetiki (ntango detected ezali LOW), epelisaka buzzer mpe ekomaka "Detected!" na Serial Monitor. Soki champ moko te emonani, ezimisaka buzzer mpe ekomaka "Nothing".

Démonstration / Nini Okoki Kozela

Ntango okosalela code, Arduino akotalaka ntango nyonso senseur ya Hall mpo na champ ya magnetiki nyonso. Soki champ ya magnetiki emonani, buzzer akoloba, mpe okomona "Detected!" ekomami na Serial Monitor. Soki champ ya magnetiki ezali te, buzzer akotikala ya kufa, mpe "Nothing" ekomonama. Keba na câblage mpo na koboya ba connexions oyo ebongolami, oyo ekoki komema na echec ya détection (na video na 06:15).
