This sensor is visible on the face of the device. So you can easily use it. Just put it close to the light.
This light meter app reports its values in lux value, and has a typical dynamic range between 1 and 30,000 lux level.
But some devices the light sensor may not be linear and not be so accurate. And some earlier devices do not have a light sensor.
Take the instantaneous measurement, keeping the highs measures, medium and minimum for better control in time
IMPORTANT..!!! This application only works on devices with Light sensor
To be used in photography, scenic design or whatever you want
Bonus: includes a sound meter and a vibrations meter.
Includes a nice graph. You can make screenshots and pause the meter.
Value is DIRECT from the phone sensor in Lux. It may differ from a normal dedicated luxmeter. Bulb Life App Icon by Nicholas Menghini from The Noun Project http://thenounproject.com/nl_menghini/.

A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include a computer, either digital or analog, which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed.
Light meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. They are used in the general field of lighting, where they can help to reduce the amount of waste light used in the home, light pollution outdoors, and plant growing to ensure proper light levels.

- You can calibrate it (many devices doesn´t provide measurements in any standard unit).
- It shows you maximun,minimum and average measures.
- Units: lux (but you can use other units introducing a multiplication factor).
It will only show measures in compatible devices.
IMPORTANT! ABOUT RESOLUTION OF MEASURES:
Because of the resolution of the light sensor of some devices like Samsung Galaxy S2, in some devices the app will only give measures with a resolution of 10^n lux ( 10 lux, 100 lux, 1.000 lux...) or other kind of scale. It´s not a bug of the app, it´s due to the resolution of the sensor of these devices.
You should also keep in mind that this software shows the measures given by the device and so, if the device sensor doesn´t give good quality measures (it happens in some devices), this software won´t either give good quality measures. Please do not vote negative in that cases.
- Direct reading in lux.
- Support maximum and minimum lux values.
- Make cool graphical charts of Lux intensity.
- Guidance for recommended light level in different work spaces like rooms hotels offices museums and other residential areas.
- Custom calibration of light.
- Keep calibration factor in preference.
Note: Be aware that the accuracy of the light sensor vary between different devices and values shown in this application are indicative.
* Measure the ambient illuminance in Lux (lx) with your light sensor.
* Simple app to detect the light of your environment. Check and compare the illuminance of different light sources. See the minimum and maximum values.
* You can also set your favorite color.
* The measured value depends on the accuracy of your device's light sensor and may differ from the real illuminance and between different devices.

This app requires devices with a light sensor. It uses native light sensor data acquisition that gives accurate and instant light intensity reading. This type of native data acquisition is available for many supported devices.
Other devices are also supported by the built-in compatibility mode but the accuracy and the speed of light intensity reading may be limited and custom calibration is required for correct reading under compatibility mode.
Custom calibration procedures are described on the following page:
Also, on some devices the light sensor may not be linear, not continuous and measuring errors will occur or the maximum measuring range may be limited. This is not app's fault.
This app also provides a light color temperature measurement in K (degrees Kelvin) that is only supported on devices employing color light sensor. On all other devices the display shows n/a (not available).

REMEMBER!! The built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB)...
SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. We had calibrated many android devices with the actual sound level meter with dB(A).
See the 4-6th pictures. I had calibrated many android devices with an actual sound level meter. You can trust the result in routine-noise levels (40-70dB). But, please use it as an auxiliary tool.
* Pro version added Features :
- Sound Meter and Vibrometer are integrated
- Statistic menu with saving log data
- CSV file exporting
- Level notification
- Line-chart duration
- More models are calibrated
- No ads
* Do you want more tools?
Get [Sound Meter Pro] and [Smart Tools] package.
For more information, see the manual, Youtube video and the blog. Thank you.
** Not compatible with: Xperia(X8, X10 mini), LG(Optimus One, P350), GT-I9001, ZTE, etc

The accuracy of the measurement depends on the accuracy of your device sensor.
For more accurate sensor readings, you can set the correction factor by using calibration feature.
Note: Some old devices doesn't have light sensor, you will receive notification at the start of the program if so.
Most probably the sensor is installed near to the front camera.
