TDK Corporation’s InvenSense ICP-10125 is part of the InvenSense SmartPressure family of the MEMS barometric pressure sensor platform. Combining barometric pressure and temperature sensing, the InvenSense ICP-10125 provides IPX8 waterproofing to more than 100 meters (10 ATM). The MEMS barometric pressure sensor offers four different measurement modes for optimizing power, noise, accuracy, and measurement frequency.

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.

The ICP-10125 achieves the industry’s lowest pressure noise of 0.4 Pa RMS, attains the industry’s lowest power consumption of 1.3 µA, and ensures excellent temperature stability with a temperature coefficient of ±0.5 Pa/°C.

The ICP-10125 is well-suited for smartwatches, fitness trackers, and outdoor IoT applications that assist in fitness activity monitoring, location tracking for E911 calls, and indoor/outdoor navigation (dead-reckoning, floor/elevator/step detection), reports TDK.

The InvenSense SmartPressure family uses an innovative capacitive MEMS architecture to deliver lower power consumption and lower noise than competing pressure sensors technologies. With its ultra-low noise and low power consumption, ICP-10125 is ideally suited for wearable fitness monitoring and battery-powered IoT. It can measure height change as small as 8.5 cm, less than the height of a single stair step.

“ICP-10125 delivers high accuracy, low power, temperature stability, and waterproofing in a small package footprint targeting the wearable market,” said Uday Mudoi, Director of Product Marketing at InvenSense, a TDK group company. “It enables determination of accurate location of E911 calls, tracks changes in elevation for activity monitoring, and extends battery life of always-on motion-sensing applications.”
