● To retrieve data from the motion sensor, run the command.
$ cat in_accel_scale_available
$ cat in_accel_*_scale
$ cat in_accel_*_raw
● To retrieve data from the pressure sensor, run the command.
$ cat in_pressure_raw
$ cat in_pressure_scale
Converting raw data for use
Apply the formula in the table to convert the raw data collected into usable measurements.
Table 11. Convert relative humidity and temperature sensor raw data
Relative humidity and temperature sensor
RH (in %) = (in_humidityrelative_raw + in_humidityrelative_offset) * in_humidityrelative_scale
Temperature (degC) = (in_temp_raw + in_temp_offset) * in_temp_scale
Table 12. Convert motion sensor raw data
Motion sensor—Accelerometer
accel_{x/y/z} (m/s^2) = in_accel_{x/y/z}_raw * in_accel_{x/y/z}_scale
Table 13. Convert pressure sensor raw data
Pressure sensor
Pressure (hPa) = in_pressure_raw * in_pressure_scale * 10
Temperature (m degC) = in_temp_raw * in_temp_scale

Ignition Pin

The ignition pin can be used to wake the system from S3, S4, and S5 power states. The user can use the operating system
power management to configure S3, S4, and S5 power states and shutdown.
NOTE: For more information about configuring the ignition pin (using the system.power-key-action command), see
https://docs.ubuntu.com/core/en/reference/core-configuration.
Specify the action to take when the power button is pressed.
