Light Level

Light Level | Order No. 3124 | (NEW PRODUCT)  

This newly designed 5 range sensor cleverly measures light levels from 0 through to 100,000 Lux.

Incorporating three sensors into one results in huge cost savings.

Four of the ranges are for general purpose use as they have filtering incorporated to eliminate the unwanted effects of modulation from room lighting (50 Hz).

The fifth range (0 to 1 K fast) has no filtering and will clearly show the modulation on an incandescent or fluorescent light. Point the sensor at a computer monitor to observe its refresh time (an EasySense logger capable of fast logging is required to monitor this rapid event).



  • Inverse Square Law
  • Environmental monitoring
  • Colorimeter experiments
  • Yeast growth
  • Absorption of light
  • AC modulation
  • Investigating interference using a Laser module – Young’s slit

The photo diode used in this sensor is sensitive to light in the range from 350 nm to 700 nm. The sensor has built-in infrared rejection filter, giving it a spectral response similar to that of the human eye.
