Description
The LTR-556ALS-01 is an integrated low voltage I2C digital light sensor [ALS] and proximity sensor [PS] with built-in emitter, in a single miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal capable of direct I2C interface. It provides a linear response over a wide dynamic range from 0.01 lux to 64k lux and is well suited to applications under high ambient brightness. With built-in proximity sensor (emitter and detector), LTR-556ALS-01 offers the feature to detect object at a user configurable distance.
