Magnetometer Sensor Manufacturers | Magnetometer Sensor vendors
This page covers Magnetometer Sensor basics with features of popular Magnetometer Sensor. It mentions Magnetometer Sensor manufacturers or Magnetometer Sensor vendors.
What is Magnetometer Sensor:
• It is an instrument with sensor which measures magnetic field.
• It measures magnetic flux density (B) in units of Tesla or Wb/m2 or kg/(A * s2).
• Magnetometers are used to detect fluctuations in the magnetic field of the earth.
• It is classified into two types viz. scalar and vector.
• Vector magnetometer measures flux density in specific direction in three dimensional space. Example: fluxgate magnetometer.
• Scalar magnetometer measures total strength of the magnetic field.
• Chip based magnetometers are usually vector type which contains three sensors mounted orthogonally i.e.
each of them at 90 degrees to the other two.
• It is used for various scientific purposes and for navigation and more. It is also used in smart phones as
compass.
• Magnetometer sensors are used along with microcontrollers.
• Refer Article on magnetometer basics and types >> for more information.
Magnetometer Sensor features
Following are the silent features of Magnetometer Sensor (HMC5883L) from Honeywell.
• It is 3-axis magnetoresistive sensor.
• It uses 12 bit ADC to deliver 1 to 2 degrees of compass heading accuracy.
• It has I2C digital interface which can be interfaced with microcontrollers or
any other controlling devices.
• It offers wide magnetic field range of measurement.
• It requires low Voltage (2.16 to 3.6V) for its operation and
consumes very low power.
• RoHS Compliance
Magnetometer Sensor Manufacturers
Following table lists popular Magnetometer Sensor manufacturers or vendors.
| Magnetometer Sensor Manufacturers | Description |
|---|---|
| Honeywell | • Model : HMC5883L • Features as mentioned above |
| Freescale Semiconductor | • Model : FXMS3110 • 3-axis magnetometer sensor |
| InvenSense | • Model: MPU-9250 • It is highly sophisticated IMU (Inertial Measurement Unit). • It includes 3-axis gyroscope in addition to 3-axis magnetometer and 3-axis accelerometer. • It can be accessed using I2C or SPI protocol. |
| ST Microelectronics (sold by Adafruit) | • Model : LSM303 • It also contains 3-axis accelerometer in addition to 3-axis magnetometer sensor. |
| Bosch Sensortec GmbH | • Module known as ecompass uses two separate sensors integrated within a single LGA package viz. 3-axis magnetometer and 3-axis accelerometer. Magnetometer is used for geomagnetic field detection and accelerometer is used for tilt compensation. |
