The LSL 100 light sensor is based on a silicon photodiode, the sensitivity of which in the infrared spectral range has been strongly reduced by the use of filters. For this reason, this component is very suitable for the detection of daylight, in particular if the infrared proportion of the spectrum is large e.g. at sunset. This component contains a built-in operational amplifier and can be used in a similar way to a photoresistor.
