Reed switch can be used as sensor for count, limit and other purposes. For instance, a kind of bike-kilometer is constituted by sticking magnetic to the tire and mounting reed switch aside. We can mount reed switch on the door for alarming purpose or as switches.
Reed switch has been widely applied in household appliances, cars, communication, industry, healthcare and security areas. Furthermore, it can also be applied to other sensors and electric devices such as liquidometer, door magnet, reed relay, oil level sensor and proximity sensor(magnetic sensor). It can be used under high-risk environment.
  • Working voltage: 5V
  • Simple structure
  • Long service life
  • Quick response speed
  • Strong anti-shock capacity and high reliability


Sample code:
int Led=13;//define LED interface
int buttonpin=3; //define magnetic reed switch interface
int val;//define digital variable val
void setup()
pinMode(Led,OUTPUT);//define LED as output interface
pinMode(buttonpin,INPUT);//define reed switch as output interface
void loop()
val=digitalRead(buttonpin);// read and assign the value of digital interface 3 to val
if(val==HIGH)//When a signal is detected by magnetic ring sensor, LED will flash
