STMicroelectronics has added a high-performance standalone 3-axis magnetometer to its MEMS sensor portfolio.
By introducing the 2 x 2 x 1mm LIS3MDL magnetometer, ST now offers unique flexibility for designers to implement movement and position detection in space-constrained products such as smartphones and personal navigation devices. The device can also be combined with other discrete sensors from ST such as 3-axis MEMS accelerometer or 3-axis MEMS gyroscope, to build sensors with as many as 9 degrees of freedom (DOF).
Using STís iNEMO Engine Sensor Fusion software, designers can further enhance location-detection capabilities by integrating additional miniature sensors from STís portfolio for multiple-DOF (M-DOF) sensing. Sensor Fusion software helps coordinate any combination of sensors from STís broad portfolio to create reliable, high-quality M-DOF systems quickly and efficiently for location-based services, enhanced motion-based gaming, and pedestrian dead-reckoning for indoor and multi-floor navigation. For example adding a MEMS pressure sensor, for altitude sensing, can enhance in-building accuracy, as well as support extended smartphone functionality and location-based operator services.
Samples of the LIS3MDL are available and mass production is scheduled for Q2 2013. Unit pricing is US$0.60 for volumes in the range of 1,000 pieces.
