Linear Magnetic Hall Switches Speed Counting Sensor

Linear Magnetic Hall Switches Speed Counting Sensor

1. has the signal output instructions.
2. single signal output.
3. effective signal output for low level.
4. sensitivity adjustable pure tone ().
5. have the field cuts have signal output
6. circuit boards output switch quantity! (can be directly by SCM)
Linear Hall magnetic module and a digital interface, built-in 13 LED build a simple circuit to

produce a magnetic field warning lamp 13 comes with digital interfaces of the LED, the linear Hall sensor magnetometer access number 3 interface, when linear Hall magnetometer Sensor senses a key signal, LED lights, otherwise off.

example code:-
int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the linear Hall magnetic sensor interface
int val ;// define numeric variables val
void setup()
{
pinMode(Led, OUTPUT) ;// define LED as output interface
pinMode(buttonpin, INPUT) ;// define linear Hall magnetic sensor output interface
}
void loop ()
{
val = digitalRead(buttonpin) ;// digital interface will be assigned a value of 3 to read val
if(val == HIGH) // When the linear Hall sensor detects a magnetic signal, LED flashes
{
digitalWrite(Led, HIGH);
}
else
{
digitalWrite (Led, LOW);
}
}
