Lsm303dlhc

The LSM303DLHC is a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. The LSM303DLHC has linear acceleration full scales of ±2g / ±4g / ±8g / ±16g and a magnetic field full scale of ±1.3 / ±1.9 / ±2.5 / ±4.0 / ±4.7 / ±5.6 / ±8.1 gauss.

How do you calibrate a magnetometer?

You might need to multiply the result by negative one depending on if your z-axis is facing toward

What instrument measures magnetic field?

magnetometer,, instrument for measuring the strength and sometimes the direction of magnetic fields, including those on or near the Earth and in space. Magnetometers are also used to calibrate electromagnets and permanent magnets and to determine the magnetization of materials.

What is ADXL345 accelerometer?

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for mobile device applications.

What is a disadvantage of a magnetometer?

➨Magnetometers are sensitive to their environment. It induces magnetic bias of two types viz. hard iron bias and soft iron bias. Hard iron bias is caused by magnetized material inside the device.

Can magnetometer be used for GPS?

In the absence of GPS — for example, if the GPS signal is jammed or the platform is underground or underwater — a magnetometer can be used in conjunction with magnetic maps to help determine the platform location.

Can a magnetometer detect guns?

Local aberrations in the magnetic field produced by ferromagnetic objects, such as guns and knives, can be detected by extremely sensitive magnetometers.

How much gauss is safe?

Magnetic fields for occupational exposures should be limited to less than 0.5 mT (5 gauss or 5,000 mG).

Can phone measure magnetic field?

With today's smart phone technology, all you need to measure the strength of any magnetic field is built right into most phones. Both iPhones and Android Phones allow measurement of magnetic fields using only the phone and a free app. There are several apps available to measure magnetic field.

What are the two methods of magnetic field?

Ans. Magnetic field can be produced by any of the following methods: (i) Any magnet-bar magnet, horse-shoe magnet or round magnet can be used. (ii) A wire carrying current produces a field around it.

Is ADXL345 a gyroscope?

ADXL345 is a 3-axis accelerometer that senses both static acceleration (due to gravity) as well as dynamic acceleration (due to motion or shock). So, it can be used as a tilt sensor or to detect free fall.

What is the difference between ADXL335 and ADXL345?

ADXL345 has a relatively smaller data distribution than ADXL335 which is still around 0° (zero degree). Researchers used ADXL345 as a sensor in the measurement of gravity acceleration based on the stability of the sensor in the measurement of the test results to obtain a stable gravity acceleration value.

What is the output of ADXL345?

The ADXL345 features 4 sensitivity ranges from +/- 2G to +/- 16G. And it supports output data rates ranging from 10Hz to 3200Hz.

Is a magnetometer still used today?

Today, magnetometers are widely used in a variety of applications. They're used to measure the Earth's magnetic field, in geographical surveys, used by the military to detect submarines, and are even used in metal/weapons detectors.

What can be detected by a magnetometer?

Magnetometers are used in geophysical surveys to find deposits of iron because they can measure the magnetic field variations caused by the deposits. Magnetometers are also used to detect shipwrecks and other buried or submerged objects.

Can a magnet damage a magnetometer?

Strong magnetic fields do have the possibility, however, to temporarily disrupt the magnetic field sensor (magnetometer), which can usually be easily re-calibrated. A strong magnet can polarize either the magnetometer or the metallic parts of the device, leading to erroneous magnetometer or compass readings.

Does Google Maps use magnetometer?

Yes…it says so right at the bottom of the screen! OK - BUT THAT'S NOT STRICTLY TRUE: Well… strictly…it's not the Google Maps SOFTWARE - it's the Google Maps DATA (the actual maps themselves).

How deep can a magnetometer detect?

In a general sense, the exploration depth of a magnetometer is unlimited. It is certainly sensitive to the Earth's field and this is generated in the Earth's Core, some 5000 km beneath our feet.

Do all phones have magnetometer?

Does your Android phone have a magnetometer? Yup, chances are that it does as most Android devices do. Even if you have an old or a cheap phone, there's likely a magnetometer inside of it.

Can a magnet divert a bullet?

Typically, no. Most bullets aren't ferromagnetic – they aren't attracted to magnets. Bullets are usually made of lead, maybe with a copper jacket around them, neither of which sticks to a magnet. These magnets made a bullet tumble on Mythbusters, but didn't change where it hit the target.
