Koodka Arduino si loo isticmaalo sensor-ka Hall ee NJK-5002C

Hordhac

Hagahan wuxuu muujinayaa sida loo dhiso nidaam lagu ogaanayo goobta magnetic iyadoo la adeegsanayo sensor-ka NJK-5002C Hall effect iyo Arduino. Mashruucu wuxuu muujinayaa sida loo isticmaalo magnet si loo kiciyo relay, kaas oo markaa xakameeya culeyska AC, sida nalka ama marwaxadda. Tani waa hab wax ku ool ah oo ammaan ah oo lagu otomaatigiyo qalabka ku shaqeeya AC iyadoo la isticmaalayo calaamad xakameyn oo danab hooseeya ah.

Fikradda asaasiga ah waxay tahay in sensor-ka Hall uu ogaado joogitaanka goobta magnetic. Marka magnet (gaar ahaan, Cirifka Koonfureed) uu ku soo dhawaado sensor-ka, wuxuu soo saaraa calaamad hooseysa. Arduino wuxuu akhriyaa calaamaddan oo wuxuu kiciyaa module-ka relay. Relay-ku wuxuu u shaqeeyaa sidii fure, isagoo ku xira ama gooya korontada AC ee culeyskaaga. Qaabkani waa dhismo aasaasi u ah mashruucyo badan oo otomaatig ah.

Waa kuwan dhawr fikradood oo mashruuc oo wax ku ool ah oo aad ku dhisi karto tignoolajiyadan:

• Iftiimin Otomaatig ah: Shido nalka marka albaab ama daaqad leh magnet la furo.
• Qalabka Amniga: Kici qaylo ama nalka marka xiriirka magnetic la gooyo.
• Tirin Khadka Soosaarka: Tiri alaabta ku socota conveyor belt markay dhaafaan sensor leh magnet ku xiran.
• Ogaanshaha Goobta: Ogaa goobta gacanta robotic ama qayb mashiin oo magnet ku xiran yahay.
• Xiritaanka Amniga: Goo korontada mashiinka marka ilaalinta amniga la furo.

Qalabka Loo Baahan Yahay

• Arduino Uno (ama board kasta oo la jaanqaadi karo)
• Sensor-ka NJK-5002C Hall Effect
• Module-ka Relay (5V)
• Culeyska AC (tusaale, nalka ama marwaxad yar)
• Xadhig Koronto oo loogu talagalay Culeyska AC
• Fiilooyinka Jumper
• Magnet (oo leh Cirifka Koonfureed oo si cad u calaamadsan)

Hagaha Xirista

Xirista mashruucan waa mid toos ah. Sensor-ka iyo module-ka relay labaduba waxay ka shaqeeyaan 5V iyo GND ee Arduino. Calaamadda ka timaadda sensor-ka waxaa lagu akhriyaa pin-ka gelinta dhijitaalka ah, relay-gana waxaa lagu xakameeyaa pin-ka soo saarista dhijitaalka ah.

Waa kuwan faahfaahinta xirista:

• Sensor-ka NJK-5002C:
  • Fiilada Brown → Arduino 5V
  • Fiilada Blue → Arduino GND
  • Fiilada Black → Arduino Digital Pin 2
• Module-ka Relay:
  • Pin-ka VCC → Arduino 5V
  • Pin-ka GND → Arduino GND
  • Pin-ka IN (ama Signal) → Arduino Digital Pin 8
• Culeyska AC:
  • Goo hal fiilo oo ka mid ah xadhigga korontada ee culeyskaaga AC.
  • Ku xir hal daraf oo ka mid ah fiilada la gooyay terminal-ka Normally Open (NO) ee relay-ka.
  • Ku xir darafka kale ee fiilada la gooyay terminal-ka Common (COM) ee relay-ka.

(fiidiyowga 05:09) Jaantuska hoose wuxuu muujinayaa xiristahan. Ogsoonow in relay-ku yahay nooc hoose-kiciya, taasoo la macno ah inuu kiciyo marka pin-ka signal-ka lagu dhigo LOW.

Sharaxaadda Koodhka

Koodhka Arduino ee mashruucan waa mid fudud oo diiradda saaraya akhrinta sensor-ka iyo xakamaynta relay-ka. Qaybaha muhiimka ah ee koodhka ee aad qaabayn karto waxay ku yaalliin dusha sare ee sketch-ka.

#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: Tani waxay qeexaysaa pin-ka dhijitaalka ah ee Arduino ee ku xiran fiilada madow ee sensor-ka Hall. Waxaad bedeli kartaa tan pin kasta oo dhijitaal ah oo la heli karo.
• #define relayPin 8: Tani waxay qeexaysaa pin-ka dhijitaalka ah ee Arduino ee ku xiran pin-ka IN ee module-ka relay. Waxaad bedeli kartaa tan pin kasta oo dhijitaal ah oo la heli karo.
• const int wait = 3000;: Kani waa doorsoome aad muhiim u ah. Wuxuu dejiyaa waqtiga millisekunud ee relay-ku sii socon doono ka dib marka magnet la ogaado. Fiidiyowga, waxaa lagu dejiyay 3000 ms (3 ilbiriqsi). Haddii aad rabto in relay-ku isla markiiba damiyo marka magnet-ka laga saaro, ku deji tan 0. (fiidiyowga 08:15)

Koodhku wuxuu kaloo isticmaalaa delay(300) dhamaadka loop-ka guud. Kani waa daahitaan debounce ah si looga hortago beddelka degdegga ah ee aan loo baahnayn ee on/off. Waxaad hagaajin kartaa qiimahan, laakiin dejinta 100 ms ilaa 300 ms guud ahaan waa mid wanaagsan oo shaqo deggan. (fiidiyowga 11:03)

Muuujinta Mashruuca Tooska ah

Muuujinta fiidiyowga, nidaamka waxaa la muujiyay isagoo la shaqaynaya nalka AC. Marka Cirifka Koonfureed ee magnet-ka loo soo dhawaado sensor-ka, LED-ka sensor-ka wuu shidmaa, Arduino wuxuu akhriyaa calaamad LOW ah, wuxuuna kiciyaa relay-ka. Tani waxay ku xirtaa korontada AC ee nalka, iyadoo shidaysa. Monitor-ka serial sidoo kale wuxuu daabacaa "Sensed".

(fiidiyowga 11:19) Waa muhiim in la ogaado in sensor-ku yahay mid dareema cirifyada. Wuxuu kaliya kici doonaa Cirifka Koonfureed ee magnet-ka. Cirifka Waqooyi lama ogaan doono. Intaa waxaa dheer, magnet-ku waa inuu aad u dhowaadaa oo si fiican u toosnaadaa wejiga sensor-ka si loo helo ogaansho lagu kalsoonaan karo. Muuujintu waxay muujinaysaa in sensor-ku uusan ka shaqeyn dhinaca ama masaafo fog.
