Comapss Sensor HMC5883L GY271

GY-273 HMC5883L Triple Axis Compass Magnetometer Sensor Module For Arduino 3V-5V

This module is based on a popular and well-loved magnetometer, the HMC5883L. This compact sensor uses I2C to communicate and its very easy to use. Since it's a 3.3V max chip, we added circuitry to make it 5V-safe logic and power, for easy use with either 3 or 5V microcontrollers. Simply connect VCC to +3-5V and ground to ground. Then read data from the I2C clock and data pins. There's also a Data Ready pin you can use to speed up reads (check the datasheet for details). The chip could be HMC5883L or QMC5883L or DA5883L.

Description

This module is based on a popular and well-loved magnetometer, the HMC5883L. This compact sensor uses I2C to communicate and its very easy to use. Since it's a 3.3V max chip, we added circuitry to make it 5V-safe logic and power, for easy use with either 3 or 5V microcontrollers. Simply connect VCC to +3-5V and ground to ground. Then read data from the I2C clock and data pins. There's also a Data Ready pin you can use to speed up reads (check the datasheet for details)

If using with an Arduino, its extra-easy to get started as we already wrote a nice little Arduino library with a matching tutorial to get you started. Simply download our library and connect the SCL pin to your Arduino's I2C clock pin, and SDA pin to your Arduino's I2C data pin and upload our test example sketch to read out magnetic field data and heading (i.e. which way is north)

This is the same magnetometer sensor that is inside the LSM303. So if you want an accelerometer as well as a magnetometer, check out the LSM303 - it has basically this sensor + a nice digital 3-axis accelerometer!

Specs:

I2C interface

1-2 degree heading accuracy

Integrated 12-bit ADC

160Hz max data rate

Range of -8 to +8 Gauss

The chip could be HMC5883L or QMC5883L or DA5883L. 

QMC5883L is made by a Chinese company, they get the production authorization of HMC5883L from Honeywell, and rename it QMC5883L. So QMC5883L and HMC5883L basically are the same, they share the same hardware design. Just their register is a bit different. We only need to change the software a bit.
