Light Intensity Lux Meter

The type of sensor is important when it comes to a lux meter because it has to perceive ambient light in a way that corresponds to the human eye. Accurate and quantifiable measurement of light is essential in creating desired outcomes in practical day to day applications as well as unique applications. The measure of the lux light meter varies depending on the light s intensity and distance.

Also light color measurement requires device with an rgb light sensor.

Light intensity lux meter.

To begin turn off any lighting in the room you re about to measure. Professional light intensity lux meter that measures illumination levels in lux. Measuring light intensity using a lux meter. How to measure light intensity using lux light meter.

Measure ambient light in the room. It is analogous to the radiometric unit watt per square metre but with the power at each wavelength weighted. In order for this meter to be exact you need to perform calibration. If a point source has no reflections a portion of the produced light reaches a surface.

Eyes have different sensitivities to colours or wavelengths and perceive yellow and green light. Lux meter is a simple light meter for measuring illuminances by using the light sensor of your device. Key features of lux meter. Turn on the light meter to establish what s known as the baseline measurement.

Using a light lux meter is the best way to measure light intensity it gives us the ability to choose the optimal light intensity for an environment. Lx is the si derived unit of illuminance measuring luminous flux per unit area. Lux meters should fulfil specific criteria in order to be able to measure the light intensity and light conditions reliably and precisely. The light intensity is shown in lux and fc.

The lux light meter s calculation of illuminance is done by using the point source process. A klux is a 1000 lux and about 1 1 klux is the minimum light requirements for any plants for at least 12 hours per day to gain any benefit from fertilization. It features direct reading in lux or fc and also displays the measured light color temperature in degrees kelvin k. This app requires device with a light sensor.

For example a typical single range light meter measures up to 2 000 foot candles fc 20 000 lux whereas a high intensity light meter with multiple measurement ranges such as the extech ea33 may have a top range of 99 990 fc 999 900 lux. From measuring the amount of light in a work space surface to ensuring emergency exits have proper illumination light measurement and analysis. In photometry this is used as a measure of the intensity as perceived by the human eye of light that hits or passes through a surface.

Luminous intensity is measured in lumens per square meter lux or lx or lumens per square foot foot candles or ft c. Measurement range accuracy resolution and sampling rate vary from meter to meter. Record your measured light illuminances create locations for your points of measuring live line chart shows the actual trend of the light intensity line chart for every record in your history supports lux lx and foot. It is equal to one lumen per square metre.
