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.
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.
If you like the program, please support us by buying ad-free version:
1. Analog and Digital Lux Meter with High, Low and Normal Levels indicating lights with sound buzzers.
2. Live Graph showing the light changes
2. Covers a large range of work-stations light requirements
3. Has a reset button for refreshing the surroundings light levels
4. Elegant user Interface
5. Displays the Minimum and Maximum Range of Lux Levels for all the workstations included.
Actually, it is a really today's need for every person working in any domain of work to facilitate a better and recommended vision for his efficient working.
- 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.
Exclusive accuracy of measurements.
We have made this Light Meter for that you could save on purchasing of professional illuminometers which cost hundreds of dollars. At the same time we love beautiful design and we like to surprise, therefore, having acquired our illuminometer you also receive the graceful and extremely convenient device with intuitive interface.
Please note that Light Meter app is not a replacement for a professional device and should be used for private purposes only.
- Unique and attractive design.
- Exclusive simplicity and convenience of use .
- Lighting fast measurements.

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.
Inspired by Smart Tools app.
- Direct reading in lux
- Support maximum and minimum lux values
- Guidance for recommended light level in different work spaces
- Auto calibration light meter by front camera.
- Custom calibration.
- Keep calibration factor in preference.
Be aware that the accuracy of the light sensor vary between different devices and values shown in this application are indicative.

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
In addition to a digital display of the light intensity in lux, lux meter on the display of two analog instruments. A linear display and a circular display. The scale can be adjusted, this is in accordance with the meaningful display.
In addition, the maximum and the minimum value is displayed.
To increase the accuracy of a calibration factor can be set. Lux Meter provides all the light sensors of your device ready for measurement, these are displayed accordingly and are Selectable if your device has multiple sensors.

Luxmetro funziona su cellulari con telecamera interna e con dispositivo dedicato per la rilevazione della luminosità.
Light meter is a simple application for measuring the light intensity with attached preview (photo) of the measure,
Light meter works on phones with internal camera and with dedicated device for detecting the brightness.
You can calibrate the application. In Calibration screen you may find a calibration slider. Drag it until the up doesn't reach the specific level of a reference of a luxmeter device. You can change calibration gain any time you need.
Use this app to study, work and play in a safe and healthy environment. When light level is too low, your eyes could suffer.
This cool looking light meter app provides a simple way of measuring lighting levels.
Professional light intensity (lux) meter for your device.
It measures illumination levels in lux.

■ up to 300000lux in ICS+
■ automatic range change
■ support for neutral filters
■ 5% max error (device dependent)
■ predefined and custom calibration
■ sensor linearity correction option
■ alternative display in fc (foot-candles)
■ display of light color temperature in K
(available only on supported 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).
With the "Light meter Luxma" you can:
1. Measure the illuminance on the optical axis of one light source.
2. To calculate the theoretical values:
- luminous flux(for light sources with a cosine diagram intensity),
- the distance to the light source,
- the illuminance.
The program uses a linear correction values coming from the light sensor.
The program implemented two methods of calibration:
1. With the light meter.
2 . Method of calculation (For light sources with a cosine diagram intensity).
Calculator is designed only for light sources with a cosine graph of intensity.
It uses gps to detect your location and automatically turn your cell to vibrate or silent mode.......when you enter the following buildings and shows current latitude nad longitude values: (U can select the specfic buildings where u want your cell to go in silent or vibrate mode through app setting )
*show current value of latitude and longitude
*turns your phone to vibrate or silent when you enter the selected building
*no internet connection required
*runs in background
