Measure the ambient illuminance in lux (lx) or foot-candle (fc) with your light sensor. Simple application to detect the intensity of light. Check and compare the illuminance of different light sources. With recording function (see below). The measured values depend on the accuracy of your light sensor. It may differ from real illuminance and between different devices. The application only works if your device has a light sensor. * Unit: lux or foot-candle * Minimum and maximum values * Diagram with average value * Adjustable sensor sensitivity * Calibrate if the sensor's values differ from real illuminance * Choose your layout color * More settings * Application can be moved to SD card RECORDING FUNCTION: Record the illuminance for up to 16 h 39 min. Select the recording time and the number of recorded values. The data can be saved or exported (for example via email). PERMISSIONS: 'Internet and network access' are needed to show the ad.
