LUX Light Meter (Light Intensity Measure)

準確和有效的工具來測量光照強度

Very accurate and effective tool to measure Light intensity by using system device Light Sensors. Very handy tool for measuring Light illuminance value by using device Light Sensor. LUX Light Meter is an incident-light meter application.

A simple app displaying the Light Sensor value from the phone to be used in Photography, Scenic Design or whatever you want, LUX Light Meter can measure the exposure without influence of the reflectivity of subject.

Remember: The accuracy of measurements depends on the sensor of your phone.

LUX Light Meter a free app for you to guide you and help you on your way. This is a incident Light Meter app that measures intensity in lUX (Light unit).

FEATURES:

Analogue dial to show current reading.

Averaging.

Automatic sensor readings (no configuration required)

Calibration Feature (you can set correction factor for more accurate sensor readings)

Measurement Units (Lux or Foot Candle)

Auto-save for user configuration

Maximum and minimum values.

Time constant options

Refresh speed.

Graph – Shows the time depedence of the Light.

Auto scale 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. Be advised that the precission and quality of this and all phone light meters is limited by the device itself. I recommend using the reflected light option, the precission can be really good.
