InvenSense ICP-10100 Waterproof, Low-Power MEMS Sensor Provides Accurate Pressure and Temperature Readings

ICP-10100 MEMS Capacitive Barometric Pressure Sensor InvenSense, a division of TDK Group. Featuring the industry's lowest pressure noise and power consumption, and excellent temperature stability, the ICP-10100 is suitable for applications such as drones, mobile devices, Internet of Things (IoT) and wearable devices.

The InvenSense ICP-10100 single-axis pressure sensor features the industry's lowest pressure noise of 0.4 Pa RMS and ultra-low power consumption of 1.3 μA at 1 Hz. The tiny MEMS pressure sensor can measure subtle pressure differences of ± 1 Pa, enabling the device to detect changes in height of less than 5 cm while providing a complete pressure operating range of 30 to 110 kPa. The temperature coefficient of ± 0.5 Pa per degree centigrade ensures Extremely good temperature stability.

The ICP-10100 pressure sensor has an embedded temperature sensor and a 400 kHz I2C bus for communication that operates in low-power 1.3-μA operation in a 3.2-Pa noisy environment and has a 0.8-Pa low-noise mode for high-performance applications The power consumption is only 5.2 μA. The device is compact, only 2 mm × 2 mm × 0.72 mm, enclosure protection class IPX8, can be used under 1.5m deep underwater for up to 30 minutes.

This sensor can be evaluated with the DK-10100 SmartMotion® Platform Development Kit. The kit comes with a Microchip G55 microcontroller and includes the software required, including InvenSense MotionLink, a GUI-based development tool, and Embedded Motion Driver (eMD) for the ICP-10100. The DK-10100 has an on-board embedded debugger to program or debug the G55 microcontroller without the need for external tools.

The sensor integrates high precision, low power consumption, temperature stability and water resistance in a small package to improve activity recognition, indoor / outdoor mobile navigation, UAV setting, and extended "always on" motion sensing Applied battery life.
