Details:

---------------

Accelerometer
-measuresaccelerationalongthreeaxesx,y,z;unitsmeasurement:m/s^2

Whenorientedalongtheaxis,thenormalvalueisequaltothegravitationalacceleration(g=~9.8m/s^2).
Withthehorizontalpositionofthedevice,thevaluesalongtheaxes:z=~9.8m/s^2,x=0,y=0).

Practice:
Usedtoautomaticallychangetheorientationofthescreenwhenyourotatethedevice,ingames,etc.

---------------

Lightsensor
-measuresillumination;unitsmeasurements:lux.

Practice:
Usedtoautomaticallyadjustthebrightness(autobrightness)

Descriptionoftest:
Testwithlamp.Whenincreasingtheillumination,theglowaroundthelampchangesfromwhitetobrightyellow.
Movedevicetothelightor,onthecontrary,gointoadarkroom.
Approximatetypicalvalues:room-150lux,office-300lux,sunnyday-10,000luxandabove.

---------------

Proximitysensor
-measuresthedistancebetweenthedeviceandtheobject;unitsmeasurement:cm.
Onmanydevices,availableonlytwovaluesareavailable:“far”and“close”.

Practice:
Usedtoturnoffthescreenwhenyoucallbyphone.
