The InvenSense ICP-10100 uniaxial pressure sensor, available from Mouser, has 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 and providing a complete pressure operating range of 30 to 110 kPa. The temperature coefficient of ± 0.5 Pa per degree Celsius ensures exceptionally 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 With a power consumption of only 5.2 μA, the device is compact, only 2 mm × 2 mm × 0.72 mm and has an IPX8 enclosure rating for up to 30 minutes under 1.5m deep water.
The sensor can be evaluated with the DK-10100 SmartMotion® Platform Development Kit, which ships with the Microchip G55 microcontroller and includes the software required, including InvenSense MotionLink, a GUI-based development tool, and embedded motion driver for the ICP-10100 (eMD) 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 functions, and to extend 'always on' motion sensing Applied battery life.
