Introduction

The HMC5983 is a temperature compensated three-axis integrated circuit magnetometer. The HMC5983 includes our state-of-the-art, high-resolution HMC118X series magneto resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. The I²C or SPI serial bus allows for easy interface. This surface-mount, multi-chip module is designed for low-field magnetic sensing for applications such as automotive and personal navigation, vehicle detection, and pointing.

Interface GY-282 HMC5983 module with Arduino Uno

Hardware and Software required

  • GY-282 HMC5983 Module
  • Arduino Uno
  • Arduino IDE

Hardware Connections

The GY-282 should be connected to Uno as follows:

Vin to 3.3V

Gnd to Gnd

SCK to A5

SDA to A4

Note: If the user want to communicate with this module using SPI, then the jumper at the front side of the module should be soldered for SPI.

Program for GY-282 HMC5983 Module

Upload the program given below to the Uno board after making the connections. Now open the serial monitor to see the output.

#include //I2C Arduino Library

#define addr 0x1E //I2C Address for The HMC5883

void setup(){

Serial.begin(9600);

Wire.begin();

Wire.beginTransmission(addr); //start talking

Wire.write(0x02); // Set the Register

Wire.write(0x00); // Tell the HMC5883 to Continuously Measure

Wire.endTransmission();

}

void loop()

{

int x,y,z; //triple axis data

//Tell the HMC what regist to begin writing data into

Wire.beginTransmission(addr);

Wire.write(0x03); //start with register 3.

Wire.endTransmission();

//Read the data.. 2 bytes for each axis.. 6 total bytes

Wire.requestFrom(addr, 6);

if(6<=Wire.available()){

x = Wire.read()<<8; //MSB x

x |= Wire.read(); //LSB x

z = Wire.read()<<8; //MSB z

z |= Wire.read(); //LSB z

y = Wire.read()<<8; //MSB y

y |= Wire.read(); //LSB y

}

// Show Values

Serial.print("X Value: ");

Serial.println(x);

Serial.print("Y Value: ");

Serial.println(y);

Serial.print("Z Value: ");

Serial.println(z);

Serial.println();

delay(500);

}
