This barometric pressure temperature sensor is equipped with TDK’s newly-launched ICP-10111 barometric pressure sensor, which is based on MEMS capacitor technology to achieve ultra-low power consumption, industry-leading relative accuracy and temperature offset coefficient.

The Gravity: ICP-10111 barometric pressure temperature sensor can measure the pressure difference with an accuracy of 1Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step.

The pressure noise can be as low as 0.4Pa, and the read data will be more stable. There is a built-in temperature sensor for air pressure compensation. The ICP-10111 offers a temperature coefficient offset of 0.5 Pa/C, more stable for long-term use. 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.

The easy to use Gravity interface makes it simple to connect to your favourite development board when used in conjunction with a gravity interface board.
