1143_0 Phidget Light Sensor 70,000 lux
The 1143_0 Light sensor can measure ambient light up to 70 kilolux (roughly equivalent to the brightness of direct sunlight).
Details
The 1143 Light sensor can measure ambient light up to 70 kilolux (roughly equivalent to the brightness of direct sunlight). 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. The sensor's output is logarithmic, so it will be more accurate at low light levels.
Some light sensors report drastically different values depending on the type of light being detected. The 1143 light sensor, however, only differs by a factor of 1.2 when measuring fluorescent light versus incandescent.
