Mini Reed Switch Module(SE013)
1 Introduction
This module is a simple reed switch module, it’s similar with the module17(Reed
switch module), but it has no analog pin, no adjustable resistor, just soldering one 10K
ohm resistor.
Specification
Operation voltage: 5V
3Pin
Size:25*15mm
Weight: 2g
2 Pinout
Digital output pin, output Low or High
signal when there current or magnetic
exists
3.example
The example show that Reed module and the interface comes with digital 13 LED
build a simple circuit to produce a Reed warning lamp 13 comes with digital interfaces
of the LED, the Reed sensor access number 3 interface, when Reed sensors Sensed a
key signal, LED lights, otherwise off.

********Code Begin********
int Led = 13 ; / / define LED Interface
int buttonpin = 3; / / define the Reed sensor interfaces
int val ; / / define numeric variables val
void setup ()
{
pinMode (Led, OUTPUT) ; / / define LED as output interface
pinMode (buttonpin, INPUT) ; / / output interface as defined Reed sensor
}
void loop ()
SunFounder{
val = digitalRead (buttonpin) ; / / digital interface will be assigned
a value of 3 to read val
if (val == HIGH) / / When the Reed sensor detects a signal, LED flashes
{
digitalWrite (Led, HIGH);
}
else
{
digitalWrite (Led, LOW);
}
}
