Fermion: ICP-10111 Barometric Pressure Sensor Wiki - DFRobot


This air pressure temperature sensor is equipped with TDK's newly lanuched 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 Fermion: 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 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.

Measure the barometric pressure, temperature and altitude in the current environment.


Connection Diagram

Connect the module to the DFRduino UNO main board (via the I2C interface) as shown in the figure below.


Sample Code

Copy the following code to Arduino IDE and burn it to DFRduino UNO.

Note: Altitude is calculated from air pressure. As air pressure is affected by weather, season, airflow, etc. so altitude data can change.
