Xiaomi Redmi Note 8 Pro 128Gb+6Gb Dual LTE [87/132] Barometer

[SR] Existing and new Android devices are STRONGLY RECOMMENDED to implement the

SENSOR_TYPE_GYROSCOPE_UNCALIBRATED sensor.

[SR] Calibration error is STRONGLY RECOMMENDED to be less than 0.01 rad/s when

device is stationary at room temperature.

SHOULD report events up to at least 200 Hz.

If device implementations include a gyroscope, an accelerometer sensor and a magnetometer

sensor, they:

[C-2-1] MUST implement a TYPE_ROTATION_VECTOR composite sensor.

If device implementations include a gyroscope and an accelerometer sensor, they:

[C-3-1] MUST implement the TYPE_GRAVITY and TYPE_LINEAR_ACCELERATION

composite sensors.

[SR] Existing and new Android devices are STRONGLY RECOMMENDED to implement the

TYPE_GAME_ROTATION_VECTOR sensor.

SHOULD implement the TYPE_GAME_ROTATION_VECTOR composite sensor.

7.3.5. Barometer

Device implementations SHOULD include a barometer (ambient air pressure sensor).

If device implementations include a barometer, they:

[C-1-1] MUST implement and report TYPE_PRESSURE sensor.

[C-1-2] MUST be able to deliver events at 5 Hz or greater.

[C-1-3] MUST be temperature compensated.

[SR] STRONGLY RECOMMENDED to be able to report pressure measurements in the range

300hPa to 1100hPa.

SHOULD have an absolute accuracy of 1hPa.

SHOULD have a relative accuracy of 0.12hPa over 20hPa range (equivalent to ~1m

accuracy over ~200m change at sea level).

7.3.6. Thermometer

Device implementations: MAY include an ambient thermometer (temperature sensor). MAY but

SHOULD NOT include a CPU temperature sensor.

If device implementations include an ambient thermometer (temperature sensor), they:

[C-1-1] MUST be defined as SENSOR_TYPE_AMBIENT_TEMPERATURE and MUST measure

the ambient (room/vehicle cabin) temperature from where the user is interacting with the

device in degrees Celsius.

[C-1-2] MUST be defined as SENSOR_TYPE_TEMPERATURE .

[C-1-3] MUST measure the temperature of the device CPU.

[C-1-4] MUST NOT measure any other temperature.

Note the SENSOR_TYPE_TEMPERATURE sensor type was deprecated in Android 4.0.

7.3.7. Photometer

Device implementations MAY include a photometer (ambient light sensor).
