Mouser now stocking InvenSense's waterproof barometric pressure sensor

February 09, 2018 // By Julien Happich
Distributor Mouser Electronics is now stocking InvenSense's ICP-10100 MEMS capacitive barometric pressure sensor. The ICP-10100 single-axis pressure sensor is claimed to achieve the industry’s lowest pressure noise of 0.4 Pa RMS and the lowest power consumption, 1.3µA at 1Hz.

The 2x2x0.72mm device measures extremely small pressure differences of ±1 Pa, which makes it capable of detecting altitude changes of less than 5cm. 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. The pressure sensor has an embedded temperature sensor and a 400kHz I 2C bus for communication. In addition to the device’s low-power mode of 1.3μA at a noise of 3.2Pa, the ICP-10100 features a low-noise mode of 0.8Pa while only consuming 5.2μA for high-performance applications. It comes in an IPX8-rated housing, making it waterproof to a depth of 1.5 m for up to 30 minutes.
