Xiaomi Pocophone F1 128Gb+6Gb Dual LTE [82/118] Photometer

[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).

7.3.8. Proximity Sensor

Device implementations MAY include a proximity sensor.

If device implementations include a proximity sensor, they:

[C-1-1] MUST measure the proximity of an object in the same direction as the screen. That

is, the proximity sensor MUST be oriented to detect objects close to the screen, as the

primary intent of this sensor type is to detect a phone in use by the user. If device

implementations include a proximity sensor with any other orientation, it MUST NOT be

accessible through this API.

[C-1-2] MUST have 1-bit of accuracy or more.

7.3.9. High Fidelity Sensors

If device implementations include a set of higher quality sensors as defined in this section, and make

available them to third-party apps, they:

[C-1-1] MUST identify the capability through the android.hardware.sensor.hifi_sensors feature

flag.

If device implementations declare android.hardware.sensor.hifi_sensors , they:

[C-2-1] MUST have a TYPE_ACCELEROMETER sensor which:

MUST have a measurement range between at least -8g and +8g.

MUST have a measurement resolution of at least 1024 LSB/G.

MUST have a minimum measurement frequency of 12.5 Hz or lower.

MUST have a maximum measurement frequency of 400 Hz or higher.

MUST have a measurement noise not above 400 uG/√Hz.

MUST implement a non-wake-up form of this sensor with a buffering capability

of at least 3000 sensor events.

MUST have a batching power consumption not worse than 3 mW.

SHOULD have a stationary noise bias stability of \<15 μg √Hz from 24hr static

dataset.

SHOULD have a bias change vs. temperature of ≤ +/- 1mg / °C.

SHOULD have a best-fit line non-linearity of ≤ 0.5%, and sensitivity change vs.

temperature of ≤ 0.03%/C°.

SHOULD have white noise spectrum to ensure adequate qualification of

sensor’s noise integrity.
