STMicroelectronics LPS22HH Element

The LPS22HH element is used to measure barometric pressure. This element is for using the STMicroelectronics LPS22HH piezoresistive absolute pressure sensor, which is featured on the X-NUCLEO-IKS01A3 environmental sensor expansion board.

The LPS22HH is a sensor element that can be imported into the Element Toolbox through the Add Element Add Element button located in the toolbox from the Embedded tab. SensorTile projects have this element imported by default.


The following properties can be changed for the LPS22HH element:


The name of the element.

I2C Driver Instance

The I2C bus used to communicate with the sensor.

I2C Address

The I2C address the element sends data to.

Output Data Rate

The data rate for the sensor to sample readings. This includes the following options:

  • 1 Hz
  • 10 Hz (default)
  • 25 Hz
  • 50 Hz
  • 75 Hz
  • 100 Hz
  • 200 Hz


The following triggers are available to execute events from within the LPS22HH element:


Execute an event when the source element connected to the LPS22HH triggers.

Pressure Read

Execute an event when pressure data is read.

Temperature Read

Execute an event when temperature data is read.


The following abilities are available for the LPS22HH element when its source element triggers:


Trigger the element(s) that follow the LPS22HH element.

Read Pressure (hPa)

Read the sensor’s pressure data in hectopascals.

Read Temperature (°C)

Read the sensor’s temperature data in Celsius.
