Hall Magnetic Sensor

The Hall Magnetic Sensor project demonstrates how to use a Hall Effect sensor module with an Arduino Mega to detect the presence of a magnetic field. The Hall Effect sensor outputs a digital signal indicating whether a magnetic field is present or not. This project includes setup instructions and Arduino code to read and display the sensor's output on the Serial Monitor.

Components Needed

• Arduino Mega
• Hall Effect Sensor Module
• Magnet (for testing)
• Jumper Wires
• Breadboard
• Power Supply

Circuit Setup

Connect the Hall Effect Sensor to Arduino Mega:

Instructions

Install Required Libraries:

No external libraries are required for this project.

Circuit Setup:

Connect the Hall Effect sensor module to the Arduino Mega as described in the circuit setup section.

Code Upload:

Open Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Testing:

Upload the code to the Arduino Mega.

Open the serial monitor in Arduino IDE (set to 9600 baud).

Bring a magnet close to the Hall sensor to observe changes in the sensor output displayed on the Serial Monitor.

Applications

Notes

Ensure the correct orientation and placement of the magnet relative to the Hall sensor for reliable detection.

Adjust the delay time in the

Experiment with different magnets and distances to understand the sensor's sensitivity and range.
