This light sensor model, is by far, one of the best sensors for both accurate, outdoor/indoor applications because of its:
1. Direct digital signal output from the sensor, so that it is easy to get the readings in lux, rather than having to do manual calculations.
2. Wide measurement range and high resolution data, making this sensor very ideal for any applications involving the measurement of light in any environment.
3. Compact, small and light size, proving this sensor to be ideal for any portable, miniature enclosure or project, like a weather station or a clock.
