A range of 3 sensors, each optimised for specific applications.
The slow response light sensor is useful for laboratory based experiments, and ideal for colorimeter type and inverse square law experiments.
The fast response light sensor is both fast and sensitive enough to capture the modulations of a fluorescent lamp or computer monitor screen.
The wide range light sensor is suitable for outdoor use in sunlight
