Technical Specifications:
Range: 0 to 100,000 Lux
(Linear response)

Resolution: 30 Lux.

Product Number: 3122

Price: $39

Description:
This general-purpose sensor is ideal for environmental monitoring.  The response is smoothed to filter out unwanted signals of higher frequencies.  The photo diode is sensitive to light in the range from 350nm to 700nm. The sensor has a built in infrared rejection filter, giving it a spectral response similar to that of the human eye.

Possible Uses:

Compare the light intensity of the sun at various times of the day and seasons.

Monitor cloud cover as part of a weather investigation.

Measure the effect of foliage on light levels transmitted to ground level.
