Measures light intensities of up to 1000 lux and connects to an Analog Input or VINT Hub port.
The 1142 Light sensor can measure ambient light up to 1000 lux (roughly equivalent to the typical lighting in a studio, or the sky on an overcast day). Each sensor has been individually calibrated, and a label has been applied to the back of the board with a calibration value which can be used in your calculations to increase measurement accuracy.
Some light sensors report drastically different values depending on the type of light being detected. The 1142 light sensor, however, only differs by a factor of 1.2 when measuring fluorescent light versus incandescent.
If you need a larger measurement range, take a look at the 1143 – Light Sensor 70,000 lux.
