Χαρακτηριστικά

The GY-271 is supposed to have an HMC5883L, but some boards have a QMC5883L which has the same basic capability, but is not compatible with the H. The GY-271 QMC5883L 3-axis Electronic Compass Module Magnetic Field Sensor is designed for low field magnetic sensing with a digital interface and it is perfect to give precise heading information. If you get a GY-271 board and observe an I2C address of 0x0C and read back nothing but zeros from the board, then you probably have a QMC5883L chip! Try this library and see if it works for you. To install this library into your Arduino environment, download the latest release file to your desktop: latest released files.

This compact sensor fits into small projects such as UAVs and robot navigation systems. The sensor converts any magnetic field to a differential voltage output on 3 axes. This voltage shift is the raw digital output value, which can then be used to calculate headings or sense magnetic fields coming from different directions.

Supply voltage: 3.0~5.5VDC
Dimensions: 0.50x0.56in
16-bit ADC low-noise AMR sensors
2 milli-Gauss field resolution
<2 degree heading accuracy
Simple control via I2C
Compact and ultra-light compass module
Use as compass sensor, non-contact controller, magnetic impeller flow meter, or linear actuator position sensor
