Hall Magnetic Sensor Module(KY-024)

The KY-024 is a magnetic sensor module that offers both digital and analog outputs. It features an adjustable sensitivity via a potentiometer.

Specifications

• Operating Voltage: 3.3V ~ 5V
• Output Type: Digital, Analog

Example Required Hardware

• Arduino board
• Jumper cables
• Hall magnetic sensor module (KY-024)

Connection

Arduino	KY-024 Hall magnetic sensor module
A0	AO
D12	DO
3.3V	+
GND	G

Example Code

The example demonstrates how to read values from the Hall magnetic sensor, outputting them in both analog and digital formats.

const int analogPin = A0;
const int digitalPin = 12;

void setup() {
  pinMode(digitalPin, INPUT);
}

void loop() {
  int valap = analogRead(analogPin);
  int valdp = digitalRead(digitalPin);
  Serial.print(valap);
  Serial.print("\t");
  Serial.println(valdp);
  delay(100);
}

Execution Results

• When no magnet is present around the module

• When a magnet is present around the module
