Blue 3Pin Magnetron MagSwitch Reed Switch Sensor Module
Description:
A reed module is a magnetic sensor that is normally open and get
closed when exposed to a magnetic field. Reed switch is an
abbreviation of the dry reed contacts a passive electronic
switching elements, and has the advantages of simple structure,
small size and ease of control, its shell is a sealed glass tube,
the tubes are installed two iron elastic reed plate, but also
filling called rhodium metal inert gas.
In peacetime, the glass tube in the two reeds made of special
materials are separated. When a magnetic substance close to the
glass tube, in the role of the magnetic field lines, the pipe
within the two reeds are magnetized to attract each other in
contact, the reed will suck together, so that the junction point of
the connected circuit communicates.
The module includes a 10 K Ohm resistor, so no additional parts
needed.
When the device is exposed to a magnetic field, the two ferrous
materials inside the switch pull together and the switch closes.
When the magnetic field is removed, the reeds separate and the
switch opens. This makes for a great non-contact switch. This
switch can carry up to 1.2A.

Test Code:
nt 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 ()
{
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);
}
}
