Introduction This is a Magnetic Induction Sensor. It senses the magnetic materials within a detection range up to 3cm. The detection range and the strength of the magnetic field are proportional. The output is digital on/off. This sensor uses the SFE Reed Switch – Magnetic Field Sensor. Specification

  • Sensing magnetic materials
  • Detection range: up to 3cm
  • Output: digital on/off
  • Detection range and magnetic field strength are proportional

Sample Code:

int ledPin = 13; // choose the pin for the LED

int inputPin = 3; // Connect sensor to input pin 3

int val = 0; // variable for reading the pin status

void setup() {

pinMode(ledPin, OUTPUT); // declare LED as output

pinMode(inputPin, INPUT); // declare pushbutton as input

}

void loop(){

val = digitalRead(inputPin); // read input value

if (val == HIGH) { // check if the input is HIGH

digitalWrite(ledPin, LOW); // turn LED OFF

} else {

digitalWrite(ledPin, HIGH); // turn LED ON

}

}
