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.
Attention! Accuracy depends on your light measurement unit not on the App! It might happen that the measured values range from low to quite high.

- 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.

Professional light intensity (lux) meter for your device.
It measures illumination levels in lux.
■ direct reading in lux
■ 0 to 1000lux in 2 ranges
■ 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)
■ realistic vintage analog look
■ tablet support
■ 18 case skins
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).
2.The use of light sensors on the phone, get the amount
of ambient light illumination.(unit:lux)
3.Select a location to import cns illumination standard
4.Determine the illumination interval, display of
qualified and unqualified.
5.It can integrate the [MDMS] web version, you can check
the online CNS illumination standard values.
Convenient and practical, concerned parents the best tools and engineering inspection.
Analogue dial to show current reading.
Maximum and minimum values.
lx or ft-c units.
4 time constant options. 3 Refresh speeds.
Graph – Shows the time depedence of the light.
Autoscale or manual (pinch & pan) Y-Axis.
Calibrate option – If you have a calibrated light meter or known light source, you can use this option to calibrate the meter. (However app is still for Indication Only).
More details can be found on the website.
- 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.
Please beware that the data accuracy depends completely of device light sensor and because of that values shown should be taken only as indicative. For professional uses it is better to use a standarized and calibrated 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.

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.
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:
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.
- Analog and digital measurement with high, low and normal levels indicating the intensity of light with sound timbres.
- Live Graph showing changes in light.
- Covers a wide range of workstations where light needs.
- It has a reset button to update the surrounding light levels.
- Shows the minimum and maximum level range Lux for all workstations. Actually, it is a necessity nowadays for everyone who frequents in any workplace to facilitate better vision and is recommended for efficient operation.
