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.
