Infineon Technologies AG has launched an ultra-high ±5cm resolution, miniature MEMS pressure sensor for use in mobile and wearable gadgets and IoT devices. The DPS310 is a low-power digital barometric pressure sensor that enables the development of new and enhanced navigation, location, well-being, gesture recognition and weather monitoring applications.
Delivering accurate and stable performance across a wide temperature range, the DPS310 is ideal for indoor navigation and assisted location applications – such as floor detection in shopping malls and parking garages– and outdoor navigation where it can help to improve navigation accuracy or support ‘dead reckoning’ when GPS signal is not available. In addition, the ability to provide accurate data for calculating elevation gain and vertical speed suits activity tracking in mobile and wearable health and sports gadgets, while ultra-precise pressure measurement opens up new possibilities for gesture recognition and the detection of rapid weather changes.
The Infineon DPS310 pressure sensor is based on the capacitive sensing principle rather than the piezo-electric principle employed in most other digital pressure sensors. This guarantees high precision across a broad range of temperatures even when temperature changes rapidly. This is clearly an advantage since the temperature inside a mobile device can change quickly due to several heat sources. … (read more)
