InvenSense ICP-10100 low-power, waterproof MEMS sensor

Monday, 19 March, 2018 | Supplied by: Mouser Electronics (Hong Kong) Ltd

The ICP-10100 MEMS capacitive barometric pressure sensor has been released by InvenSense, a TDK Group company. The single-axis pressure sensor achieves low pressure noise of 0.4 Pa RMS and low power consumption of 1.3 µA at 1 Hz.

The tiny MEMS sensor measures 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 good temperature stability with a temperature coefficient of ±0.5 Pa/°C.

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 product features a low-noise mode of 0.8 Pa while only consuming 5.2 μA for high-performance applications. The 2 x 2 x 0.72 mm device includes an IPX8-rated housing, making it waterproof to a depth of 1.5 m for up to 30 min.

The combination of low power, temperature stability and waterproofing in a small footprint is intended to enable improved activity identification, mobile indoor and outdoor navigation, altitude-hold in drones and extended battery life in motion-sensing applications such as drones, mobile devices, the Internet of Things (IoT) and wearables.
