You could use it for magnetic fingerprinting for example which uses variations in magnetic fields in a known fixed location to determine where you are indoors.
3 axis magnetic sensor arduino.
The sensor class in the magnetometer library reports x y and z axis magnetometer readings directly in micro teslas the lis3mdl demo example code reads from the sensor and prints the micro tesla readings to the serial monitor.
To measure the magnetization of a magnetic material like a ferromagnet or to measure the strength and in some cases the direction of the magnetic field at a point in space.
The compass module is designed for low field magnetic sensing with a digital interface and perfect to give precise heading information.
3 axis magnetic field sensor.
This compact sensor fits into small projects such as uavs and robot navigation systems.
Or it makes a great contactless.
Hmc5883l is a 3 axis digital compass used for two general purposes.
The qmc5883l is in a 3x3x0 9mm3 surface mount 16 pin land grid array lga package.
The mgs1600gy includes a 3 axis gyroscope that can be used to provide additional stability and guidance to the vehicle.
Gy 273 hmc5883l 3 axis compass magnetometer sensor board module iic i2c for arduino 3 5v power high accurancy.
Features benefit 3 axis magneto resistive sensors in a 3x3x0 9 mm3 land grid array package lga guaranteed to operate over an extended temperature range of 40 c to 85 c.
Communication with the hmc5883l is simple and all done through an i2c interface.
In the absence of any strong local magnetic fields the sensor readings should reflect the magnetic field of the earth between 20 and 60 micro teslas.
The sensor is equipped with four leds for easy monitoring and diagnostics.
The sensor converts any magnetic field to a differential voltage output on 3 axes.
The sensor incorporates a high performance basic like scripting language that allows users to add customized functionality to the sensor.
An integral part of the research on wireless power i.
Hiletgo gy 271 qmc5883l 3 5v iic triple axis compass magnetic sensor module electronic compass module for arduino 3 2 out of 5 stars 29.
This device has a very wide measurement range from 5 50mt making it useful for far more than just orientation sensing toward a magnetic pole.
Wireless power transfer systems are well on their way to replacing conventional wired charging.
