STMicroelectronics has added a new high-performance standalone 3-axis magnetometer to its MEMS sensor portfolio. Because of its small size and performance, the sensor is suitable for mobile phones, tablets or personal navigation devices. The standalone magnetometer is also suited to indoor navigation applications where it reliably calculates dead-reckoning when no satellite signal is available.
By introducing the 2 x 2 x 1mm LIS3MDL magnetometer, ST is now able to now much greater 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 ST’s iNEMO Engine Sensor Fusion software, designers can enhance location-detection capabilities by integrating additional miniature sensors from ST’s portfolio for multiple-DOF (M-DOF) sensing. Sensor Fusion software helps coordinate any combination of sensors from ST’s 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.
“By introducing our first discrete magnetometer and offering high performance and low power consumption, we can now offer customers a complete range of standalone and integrated miniature sensors,” said Fabio Pasolini, General Manager, Motion MEMS Division, STMicroelectronics. “Designers can partition their multiple-degrees-of-freedom sensor designs with optimal performance.”
Samples of the LIS3MDL are available and mass production is scheduled for Q2 2013.
