Keyestudio EASY plug Hall Magnetic Sensor


The Hall sensor is based on Hall Effect. It can detect whether there is a magnetic object nearby or not. And it correctly tells you through digital output.
This sensor uses the SFE Reed Switch - Magnetic Field Sensor. It can sense the magnetic materials within a detection range up to 75px.
The detection range and the strength of magnetic field are proportional.
It is useful for non-contact/waterproof type switches, position sensors, rotary/shaft encoders.
Note: this sensor needs to be used together with EASY plug control board.


  • Connector: Easy plug
  • Sensing magnetic materials
  • Detection range: up to 75px
  • Output: Digital ON/OFF
  • Detection range and magnetic field strength are proportional

Technical Details

  • Dimensions: 41mm*20mm*18mm
  • Weight: 4.4g

Connect It Up

Connect the EASY Plug Hall Magnetic sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload.

int ledPin = 13;// choose the pin for the LED
int inputPin = 9;// Connect sensor to input pin 9
int val = 0;// variable for reading the pin status
void setup() {
pinMode(ledPin, OUTPUT);// declare LED as output
pinMode(inputPin, INPUT);// declare push button as input
void loop(){
val = digitalRead(inputPin);// read input value
if (val == HIGH) { // check if the input is HIGH
digitalWrite(ledPin, LOW);// turn LED OFF
} else {
digitalWrite(ledPin, HIGH);// turn LED ON

What You Should See

When a magnet is approaching to the sensor, the LED will be turned on. Otherwise, the LED is off.
