It is compatible with Arduino and can be integrated into projects that require the detection of the presence or absence of a magnetic field. Tutorial: How to use Magnetic Reed KY-025 The Magnetic Reed KY-025 is a simple magnetic sensor that can be used to detect the presence of a magnetic field. Ideal for projects such as doors and windows, home security systems, or any application where it is necessary to monitor the opening or closing of a door or a safe. What is needed Arduino Uno Magnetic Field (magnetic bar) Jumper Cable Steps Connect the VCC pin of the KY-025 module to the 5V of the Arduino. Connect the GND pin of the KY-025 module to the ground of the Arduino. Connect the OUT pin of the KY-025 module to a digital pin of the Arduino (e.g., pin 2). Test the connection with a multimeter or an LED to check the logic output. Write and upload the following Arduino sketch to your microcontroller. Position the Magnetic Reed module near the magnetic field (magnetic bar) that moves when you open or close a door. Test the functionality of the sensor by monitoring the logic output with an LED connected to the digital pin of the Arduino. Example code: const int reedPin = 2; // input pin for the Reed module void setup() { pinMode(reedPin, INPUT); } void loop() { if (digitalRead(reedPin) == HIGH) { Serial.println(
