Magnetic Senzor (Hall) Brick

Product Description

This is a brick component specially design for the Arduino board, used to detect the presence of a magnet field.

It connects with just three wires to Arduino ( GND and VCC for power, and OUT for the output signal) and it delivers 5V (digital “1”) on the OUT pin whenever there is no magnet present and 0v otherwise.

The GND pin on the brick should be connected to the GND pin on the Arduino board, the VCC pin on the brick should be connected to the VCC pin on the Arduino board, and the OUT pin on the brick should be connected to a digital pin on the Arduino board(do avoid digital pins “0” and “1” and those are used for programming purposes).

The source code is below :

void setup() 
{                
  Serial.begin(9600);
  pinMode(7, INPUT);
}

void loop() 
{
  int valoareSenzorMagnetic = digitalRead(7);
  Serial.print("Senzor magnetic: ");
  Serial.println(valoareSenzorMagnetic, DEC); 
  delay(100);
}
