Low-Power, Waterproof MEMS Sensor
Low-Power, Waterproof MEMS Sensor

The InvenSense ICP-10100 single-axis pressure sensor, available from Mouser Electronics, achieves the industry leading pressure noise of 0.4 Pa RMS and power consumption of 1.3 µA at 1 Hz. The tiny MEMS sensor measures extremely small pressure differences of ±1 Pa, which enables the device to detect altitude changes of less than 5 cm. The sensor offers a full pressure operating range of 30 to 110 kPa and ensures excellent temperature stability with a temperature coefficient of ±0.5 Pa per degree Celsius.

Waterproof for up to 30 minutes

The pressure sensor has an embedded temperature sensor and 400 kHz I2C bus for communication. In addition to the device’s low-power mode of 1.3 μA at a noise of 3.2 Pa, the ICP-10100 features a low-noise mode of 0.8 Pa while only consuming 5.2 μA for high-performance applications. The small 2 mm × 2 mm × 0.72 mm device includes an IPX8-rated housing, making it waterproof to a depth of 1.5 m for up to 30 minutes.

Development kit available

For evaluation, the sensor is supported by the DK-10100 SmartMotion® Platform Development Kit. The kit is based on a Microchip G55 microcontroller and comes with necessary software, including InvenSense MotionLink, a GUI-based development tool, and embedded Motion Drivers (eMD) for ICP-10100. The DK-10100 includes an onboard embedded debugger, removing the need for external tools to program or debug the G55 microcontroller. The combination of high accuracy, low power, temperature stability, and waterproofing in a small footprint enables improved activity identification, mobile indoor and outdoor navigation, altitude-hold in drones, and extended battery life of always-on motion-sensing applications.
