The devices have three selectable integration times and provide a direct 16-bit lux output via an I2C bus interface. The wide dynamic range of the ALS makes it particularly useful in outdoor applications where it is exposed to direct sunlight. The device is ideal for use in automatic control of street lights and security, billboard, and automotive lighting. The TSL4531 devices can also be used in solid state and general lighting for automatic control and daylight harvesting to maximize energy conservation. Other applications include display backlight control to extend battery life and optimize visibility in cell phones, tablets, and notebooks.
