DISCONTINUED
This product has been discontinued and replaced by: Digital Magnetic sensor
Introduction
This is the DFRobot Magnetic Induction Sensor. It senses the magnetic materials within a detection range up to about 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
- Senses magnetic materials
- Detection range: up to 3cm

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

}
void loop(){
