TDK’s SmartPressure™ products

  • PDF
    •                
TDK InvenSense’s barometric pressure sensors use an innovative capacitive MEMS architecture to deliver lower power consumption and lower noise than competing technologies. The SmartPressure products can measure height change below 5 cm, less than the height of a single stair step.
With its industry-leading measurement accuracy and ultra-low power operation for always-on applications, the SmartPressure product family is best suited for smart phones, tablets, wearables, drones, and many other devices to determine accurate location of E911 calls, track changes in elevation for activity monitoring, support indoor or 3D navigation, and other motion- or position-based services. Home appliances such as washing machines, vacuum cleaners, water and gas meters can use the pressure sensors to monitor air flow or water level.
The SmartPressure product family includes support for waterproofing to 10 ATM.
A Development Kit is available for each product family for easy evaluation.

SmartPressure™ Applications

Table 1 : SmartPressure™ Applications

E911

Wearable Fitness Monitoring

Mobile Phones

Drones

With its accurate measurement and low power consumption, our pressure sensors enables support for E911 service for Smartphone, Tablets and other mobile devices. It easily exceeds the +/-3m height accuracy (e.g., floor determination) specified by FCC for E911 (emergency) calls.

Support for IPX8 waterproofing protects the device up to 10 ATM. This will offer a new level of device confidence in this ever-ruggedizing industry, and is perfect for tracking all kinds of fitness activity.

With mobile phones in almost everyone’s pockets, using our MEMS pressure sensors makes indoor positioning even more accurate as well a providing the best elevation data for exercise activities.

With waterproofing and small footprints our MEMS pressure sensors are great for the needs of drones, which require the most efficient ratio of weight to power distribution, and operate in various weather conditions.
