Gravity: ICP-10111 Pressure Sensor
Description
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.
