Product Features

Measures light intensities of up to 70 kilolux on a logarithmic scale and connects to an analog input. Both incandescent and fluorescent light can be measured.
Product Description

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.

If you want greater resolution with a smaller measurement range, take a look at the 1142 – Light Sensor 1000 lux.
