Description

This Arduino compatible Linear Hall Effect Sensor is used to detect magnetic fields. It reacts in the presence of a magnetic field. It has a built-in potentiometer on the module to adjust the sensitivity of the sensor and it supports both analog and digital outputs.

The current, and thus the voltage, running through the sensor is changed in relation to the presence of a magnetic field. This Linear Hall Effect sensor is designed so it can tell you the amount the voltage has changed as an analog output, and if the voltage has changed as a digital output. Since the sensor can provide digital and analog outputs, there is a surprising amount you can do with it. You can easily make a working sensor, or make a much more complicated one.

This sensor is built in such a way that the sensor itself has everything needed to operate, including an LED. As such, you can get a basic magnetic switch with nothing more than a 5V battery by connecting the magnet ports to the + and G pins. When a magnet is brought close to the sensor, the voltage will change and send a signal to the sensors integrated LED, telling it to light up.

Test Code

int Led = 13; // define LED Interface
int buttonpin = 3; // define the linear Hall magnetic sensor interface
int val; // define numeric variables val

void setup () {
pinMode(Led, OUTPUT); // define LED as output interface
pinMode(buttonpin, INPUT); // define linear Hall magnetic sensor output interface
}

void loop () {
val = digitalRead(buttonpin); // digital interface will be assigned a value of 3 to read val

// When the linear Hall sensor detects a magnetic signal, LED flashes
if (val == HIGH) {
digitalWrite(Led, HIGH);
}
else {
digitalWrite(Led, LOW);
}
}
