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, b...
