What is HMC5883L?

What is HMC5883L?

The Honeywell HMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low- cost compassing and magnetometry.

How does a 3 axis compass work?

3-Axis Electronic Compass – Similar to the electronic compass, the 3-axis electronic compass can be used when idle, or moving at low speeds. This compass is also tilt compensated, meaning the device can be held in any position and will still give a compass reading. At times, this compass may also require calibration.

What is magnetometer Arduino?

Magnetometers measure the magnetic field along one or more axes. With a magnetometer, you can turn your Arduino into a digital compass. They’re great for navigation and guidance systems in remote controlled vehicles. You can even use them to detect electric currents in wires.

How do I calibrate my hmc5883l?

To calibrate the compass the bot will have to be turned several times….Connect the sensor to the (I2C-) GPIO pins on the Pi as follows:

1. Connect VCC to pin-1 (3.3. V)
2. Connect SDA to pin-3 (SDA = System Data)
3. Connect SCL to pin-5 (SCL = System Clock)
4. Connect GND to pin 7 (GND)

What is triple axis magnetometer?

Close. Sense the magnetic fields that surround us with this handy triple-axis magnetometer (compass) module. Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields.

How does Arduino magnetometer work?

Magnetic field is a function of position, so it is different at every point in space. This device uses three sensors, one to measure the x, the y, and the z component of the magnetic field at a point. The sensors are near to each other but not at a single point, and this limits the magnetometer resolution.

Can magnetometer detect gold?

The magnetometer can only detect ferrous (iron or steel) objects. If the gold is stored in an iron box or has iron materials next to the gold (such as colonial ship ballast stones in the marine environment), there is the possibility of detecting the iron material.

What does a fluxgate magnetometer measure?

Fluxgate magnetometers deliver magnetic field measurements by periodically saturating a piece of ferromagnetic core material to modulate the local magnetic field and sensing this modulated magnetic field using a coil of wire.

What is the output of a magnetometer?

The magnetometer measures the intensity of the magnetic field around the camera in microteslas (μT). The magnetometer determines the orientation of the earth magnetic field which gives the absolute orientation of the camera according to the north magnetic pole.

How does a MEMS magnetometer work?

The magnetometer consists of a silicon resonator, torsional beam, excitation coil, capacitance plates and glass substrate. Working in a resonant condition, the sensor’s vibration amplitude is converted into the sensing capacitance change, which reflects the outside magnetic flux-density.

What is hmc5883l example code?

Example Code. Applications. Datasheet. HMC5883L is a magnetometer module developed by Honeywell using anisotropic magnetoresistive technology. It is a multichip module that behaves as a digital compass IC to find the direction and measures the magnitude and direction of the magnetic field along the X, Y and Z-axis.

How to connect hmc5883l module to Arduino?

The connections are simple. Connect Vcc to +5V and ground to the ground pin of Arduino. Connect the communication pins SCL and SDA to analog pin 5 and 4 or Arduino. Programming of this HMC5883 module is very easy with James Sleeman’s HMC5883L library.

What is hmc5883l 3-axis compass module?

HMC5883L 3-Axis Compass Module Interfacing with Arduino HMC5883L is a magnetometer module developed by Honeywell using anisotropic magnetoresistive technology. It is a multichip module that behaves as a digital compass IC to find the direction and measures the magnitude and direction of the magnetic field along the X, Y and Z-axis.
