Description

This Arduino compatible Analog Hall Effect Magnetic Sensor Module is used to detect the relative strength of a magnetic field. It uses a Hall Effect Magnetic Sensor to differentiate between the North and South pole of the magnet.

This Analog Hall Effect Magnetic Sensor Module consists of three pins. The sensor must be connected to GND and 5V of the Arduino board. The output voltage is measured by analog pin A5 on the Arduino board. The strength of the field is given by an analog voltage at the signal pin of the module. The output of the module increases in the presence of a magnetic field and it decreases in the absence of a magnetic field. By using a potentiometer, you can adjust the sensitivity of the sensor.

The example program measures the output voltage of the sensor and presents the measured value in the serial monitor of the Arduino. The LED on the board flashes at a speed dependent on the strength of the magnetic field. This can be demonstrated with a small magnet.

Test Code

int sensorPin = A5; // select the input pin
int ledPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor

void setup () {
pinMode (ledPin, OUTPUT);
Serial.begin (9600);
}

void loop () {
sensorValue = analogRead (sensorPin);
digitalWrite (ledPin, HIGH);
delay (sensorValue);
digitalWrite (ledPin, LOW);
delay (sensorValue);
Serial.println (sensorValue, DEC);
}
