New Miniature Pressure Sensor from STMicroelectronics
Tiny sensor leveraging ST MEMS expertise boosts smartphone support for location-based services and new high-value apps.
The new LPS25H miniature barometric pressure sensor from STMicroelectronics enables a wide range of new
mobile apps with enhanced location based sensing.
Demands for new and better smartphones and tablets will accelerate the global market for pressure sensors
like the LPS25H to $375 million by 2017 for consumer electronic applications, according to IHS1.
The sensors improve indoor navigation, enabling accurate floor detection and enhanced location-based services.
Barometric pressure data also aids dead-reckoning calculations and opens the door to new smartphone apps such as weather analyzers and health and sports monitors.
The LPS25H is a MEMS (Micro-Electro-Mechanical Systems) sensor, benefiting from ST's position as the world's top MEMS supplier and owner of over 900 MEMS-related patents and patent applications worldwide.
The unique features of this sensor include enhanced temperature compensation which allows apps to perform consistently in changing environments.
In addition, auto-zero capability allows instant accuracy upon entering a building together with additional value-added features like thresholds and interrupts.
In addition to mobile applications, ST's LPS25H is also used in wearable, industrial, and smart-home systems.
Commenting on the first design wins by the LPS25H, Francesco Italia, General Manager, High-End Sensor and Analog Division, STMicroelectronics, said, “ST's new pressure sensor combines advanced functionality and best-in-class quality,
giving our customers the confidence to deliver innovative new products to market ahead of the curve.
We expect new smartphones containing the LPS25H to enjoy considerable success, offering great features that deliver significant added value for end users.”
The tiny 2.5mm x 2.5mm x 1mm sensor occupies minimal space and has very low operating current of 4µA to preserve battery life.
Ultra low-noise design helps ensure accuracy to within ±0.2mbar.
