Arduino Beginner Experiments: Arduino and Linear Hall Sensor

HELLO THERE!!!

      How are you,guys? I hope everyone is fine and in a good mood always. This week I wanted to share with you guys a simple experiment I did over the weekend. The objective of this week's experiment is to receive basic feedback from the linear hall sensor.


What is a Linear Hall Sensor?

 Basically a linear hall sensor is a magnetic module with a digital interface. The sensor also has a built in LED in it.The sensor can detect magnetic field, thus making it useful in many projects (magnetic door lock to name a few).


HARDWARE:
1.Arduino UNO ( you can use other Arduino)

2.Linear Hall Sensor

SOFTWARE:

1.Arduino IDE

CIRCUIT ASSEMBLY

Referring to the sensor image below:

SENSOR                     ARDUINO

G               ---------->  GND

+               -----------> 5V

D0            -----------> Digital pin 8 (any digital pin)

CODING THE ARDUINO

int led=13; //initializing led pin in digital pin 13(built in led)

int hals=8;// initializing hall sensor in digital pin 8

void setup() {

pinMode(led, OUTPUT);// defining led as OUTPUT

Serial.begin(9600);//serial communication at 9600 bps

}

void loop() {

 if (digitalRead(hals)== HIGH) // read the digital value sensor and if the sensor value is high

 {

  digitalWrite(led,HIGH); //turn on the led 

  Serial.println("HIGH");//print out "HIGH"

 }

  if (digitalRead(hals)== LOW)// read the digital value sensor and if the sensor value is high

 {

  digitalWrite(led,LOW);//turn of the led

  

 }

}

   Upload the code to arduino and test it!! Bring the magnet close to the sensor and see the response and feedback of the sensor. A demo video is shown below:

    Well, that's all from me guys, this week. I hope to see you guys next week and till then, HAPPY TINKERING!!!
