Arduino Uno Hall Magnetic Sensor

This project demonstrates how to use a Hall effect magnetic sensor with an Arduino Uno to detect the presence of a magnetic field.

The sensor outputs a digital signal which is read by the Arduino.

When a magnetic field is detected, the sensor outputs a low signal; otherwise, it outputs a high signal.

The result is displayed on the serial monitor.

Components Needed

• Arduino Uno
• Hall Effect Magnetic Sensor
• Jumper Wires
• Breadboard

Block Diagram

Hardware Wiring Explanation:

Connect the Hall Effect Sensor to Arduino Uno:

Software (Arduino IDE):

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Uno.

Power the Arduino

Plug the Arduino into a USB port or power it with an external adapter.

Monitor the Output:

Open the serial monitor with a baud rate of 9600.

Bring a magnet close to the Hall effect sensor and observe the serial monitor output displaying the sensor state.

Applications

Notes

Ensure the Hall effect sensor is correctly connected to the Arduino Uno and powered.

The sensor outputs a low signal when a magnetic field is detected and a high signal when no magnetic field is detected.

Adjust the code if necessary to fit your specific application requirements.
