3 Axis Magnetic Sensor Arduino

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.

3 axis magnetic sensor arduino.

The magnetic sensor is represented as a box connected to the ground and the 5v pin of the arduino board. 3 axis magnetic field sensor. The sensor has a full scale range of 8 to 8 gauss and a resolution of up to 5 milli gauss. 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.

The sensor converts any magnetic field to a differential voltage output on 3 axes. The hmc6343 is a fully integrated high end digital compass module that can compute and give the user a heading direction that s accurate within a couple degrees. 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. 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.

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. The sensor class in the magnetometer library reports x y and z axis magnetometer readings directly in micro teslas the magsensor example code reads from the sensor and prints the micro tesla readings to the serial monitor. If the 3 3v supply is used this sensor can output roughly from 0 to 3 3v. The mlx90393 isn t just one more 3 axis magnetometer.

Hmc5883l is a 3 axis digital compass used for two general purposes. Wireless power transfer systems are well on their way to replacing conventional wired charging. An integral part of the research on wireless power is. Communication with the hmc5883l is simple and all done through an i2c interface.

That means you will need to connect power ground and only two cables to arduino uno board sda scl. The circuit for the arduino uno had a 5v supply voltage but the circuit for the arduino mkr1010 used a 3 3v supply voltage instead. The hmc5883l sensor is a 3 axis digital magnetometer ic designed for low field magnetic sensing. This compact sensor fits into small projects such as uavs and robot navigation systems.

The sink is in fact a transistor that conducts when a magnet is close to the sensor and does not if the magnet is far from it. 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. Assuming a sensitivity still of 5mv gauss the sensor can measure magnetic fields of 1 65v 1gauss 0 005v 330gauss.

If you try to measure the voltage between. 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. The ic combines 3 axis magneto resistive sensors and 3 axis mems accelerometers analog and digital support circuits a microprocessor and. Ranging from tiny biomedical implants all the way to wirelessly recharging huge electric vehicles.

It is tilt compensated and is calibrated to handle magnetic distortions.
