ICP-10125

High Accuracy, Low Power, 10 atm Waterproof Barometric Pressure & Temperature Sensor IC

The ICP-10125 pressure sensor is based on MEMS capacitive technology which provides ultra-low noise at the lowest power, enabling industry leading relative accuracy, sensor throughput, and temperature stability. The pressure sensor can measure pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step.

Consuming only 1.3 μA @1 Hz, the device is available in a small footprint 3.55 × 3.55 × 1.45 mm chimney package with waterproofing gel providing IPx8 waterproofing to 10 atm. The ICP‑10125 is ideally suited for wearable fitness monitoring and battery powered IoT.

The ICP-10125 offers an industry leading temperature coefficient offset of ±0.5 Pa/ºC. The combination of high accuracy, low power, temperature stability, waterproofing in a small footprint enables higher performance barometric pressure sensing for sports activity identification and mobile indoor/outdoor navigation.

Wearable Fitness Monitoring

E911

Mobile Phones

Drones

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 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.

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.
