Sensor Fusion is the process where data from everal different sensors are fused to complete computations that a single sensor could not handle. An example of sensor fusion is computing the orientation of a device in 3-dimensional space using an accelerometer and magnetometer. That data might then be used to alter the perspective presented by a 3D GUI or game.
Freescale’s MAG3110 is a small, low-power, digital 3-axis magnetometer. The device can be used in conjunction with a 3-axis accelerometer to realize an orientation independent electronic compass that can provide accurate heading information. It features a standard I2C serial interface output and smart embedded functions.
FXOS8700CQ is a small, low-power 6-axis linear accelerometer and magnetometer combined into a single package. The device features a selectable digital I2C or SPI serial interface with 14-bit accelerometer and 16-bit magnetometer resolution along with smart-embedded functions. FXOS8700CQ is available in a plastic QFN package and it is guaranteed to operate over the extended temperature range of -40°C to +85°C.
The MMA8652FC is an intelligent, low-power, three-axis, capacitive micromachined accelerometer with 12 bits 10 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions enable overall power savings, by relieving the host processor from continuously polling data. There is access to either low-pass or high-pass filtered data, which minimizes the data analysis required for jolt detection and
The MPL3115A2 is a compact piezoresistive absolute pressure sensor with an I2C interface. MPL3115A2 has a wide operating range of 20 kPa to 110 kPa, a range that covers all surface elevations on earth. The fully internally compensated MEMS in conjunction with an embedded high resolution 24-bit equivalent ADC provide accurate pressure (Pascals)/altitude (meters) and temperature
(°C) data. The internal processing in MPL3115A2 removes compensation and unit conversion load from the system MCU, s
