App Description
This app shows illuminance - the intensity of light on your device's surface
As most mobile devices include an ambient light sensor, the ambient light level can be easily measured and displayed in analog and digital form. Our Lux Meter app shows the value of this illuminance accurately, in either 'lux' or 'foot-candle' units. Moreover, a six-second graph allows you to simply see its evolution over time.
There are three control buttons:
1. UNITS, the first button from the left, changes the unit of measurement (the option is saved).
2. CALIBRATION, the middle button, shows you the calibration cursor. Using a professional measurement tool, you can linearly calibrate the readings with a factor between 0.5 and 1.5 (this factor is saved).
3. The third button, RESET, clears the current AVG and MAX values as well as the old data.
Key features:
- two additional values, AVERAGE and MAXIMUM
- simple Calibration procedure
- large fonts for the current value
- auto-range function (100 and 1000 are the steps)
- graphical display of the last data (6-second length)
- no intrusive ads
