Library

Download and install the DFRobot_ICP Library. (About how to install the library?)

Communication Protocol Description

The sensor communicates with the main controller via the I2C protocol. The pin definitions for I2C are:

• SCL: I2C Clock Pin
• SDA: I2C Data Pin

API Description

• DFRobot_ICP10111 icp;: Create an instance of the sensor.
• icp.begin(): Initialize the sensor. Returns 0 on success, non-zero on failure.
• icp.setWorkPattern(mode): Set the sensor's work mode. The modes are:

  API	Mode	Conversion Time(ms)	Pressure RMS Noise(Pa)
  icp.eLowPower	Low Power	1.8	3.2
  icp.eNormal	Normal	6.3	1.6
  icp.eLowNoise	Low Noise	23.8	0.8
  icp.eUltraLowNoise	Ultra-low Noise	94.5	0.4

• icp.getAirPressure(): Get the current air pressure in Pa.
• icp.getTemperature(): Get the current temperature in ℃.
• icp.getElevation(): Calculate and get the current altitude in meters (based on air pressure).

Principle

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. There is a built-in temperature sensor for air pressure compensation.
