Sensor Test

Application for testing sensors

Your can test sensors in your smartphone.

Supported sensors:
- Accelerometer
- Light sensor
- Proximity sensor
- Magnetometer
- Gyroscope
- Barometer (pressure sensor)
- Compass

If sensor registered in system, it will be have green indicator, otherwise it will be red.

If sensor don't report any data, it will be with label "no data" on sensor test screen. Than most situations it means that devices doesn't have it type of sensor, for other case it not working.

If all sensors don't report any data, it usually mean problem with communication sensors via sensor service. In most cases it happen after firmware update. Sensors doesn't work in all apps.

Showed total available sensors count. When press to it opened list of the sensors. You can test all of them with graph view.

Also useful for developers, who build custom kernels.


Details:

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

Accelerometer
- measures acceleration along three axes x, y, z; units measurement: m/s^2

When oriented along the axis, the normal value is equal to the gravitational acceleration (g = ~ 9.8 m/s^2).
With the horizontal position of the device, the values along the axes: z = ~ 9.8 m/s^2, x = 0, y = 0).

Practice:
Used to automatically change the orientation of the screen when you rotate the device, in games, etc.

Description of test:
Test football. When the device is tilted, the ball should move in the direction of inclination. Try to score the ball into the goal.

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

Light sensor
- measures illumination; units measurements: lux.

Practice:
Used to automatically adjust the brightness (auto brightness)

Description of test:
Test with lamp. When increasing the illumination, the glow around the lamp changes from white to bright yellow.
Move device to the light or, on the contrary, go into a dark room.
Approximate typical values: room - 150 lux, office - 300 lux, sunny day - 10,000 lux and above.

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

Proximity sensor
- measures the distance between the device and the object; units measurement: cm.
On many devices, available only two values are available: “far” and “close”.

Practice:
Used to turn off the screen when you call by phone.

Description of test:
Test with lamp. Close the sensor by hand, the light goes out, open - light up.

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

Magnetometer
- measures the magnetic field readings in thre
