Introduction 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. Specification

  • 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 { digitalWrite(Led,HIGH); } else { digitalWrite(Led,LOW); } } See product video: https://youtu.be/28YEHO3O3XQ
