TDK Invensense’s ICP-10111 is ideal for mobile phones, wearable fitness monitoring, drones, and battery-powered IoT

TDK Invensense’s ICP-10111 barometric pressure sensor is based on MEMS capacitive technology, which provides ultra-low noise at the lowest power, enabling excellent relative accuracy, sensor throughput, and temperature stability. The pressure sensor can measure pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 5 cm, less than the height of a single stair step.

Consuming only 1.3 µA at 1 Hz, available in a small footprint 2.0 mm × 2.5 mm × 0.92 mm 8-pin LGA package, the ICP-10111 is ideally suited for mobile phones, wearable fitness monitoring, drones, and battery-powered IoT.

The ICP-10111 offers a temperature coefficient offset of ±0.5 Pa/°C. The combination of high accuracy, low power, and temperature stability in a small footprint enables higher performance barometric pressure sensing for sports activity identification, mobile indoor/outdoor navigation, and altitude-hold in drones.
