Description
The LTR-507ALS-WA is an integrated I2C digital light sensor [ALS] and proximity sensor [PS] with built-in LED driver, in a miniature chipled lead-free surface mount package. This device converts light intensity to a digital output signal capable of direct I2C interface. It provides a linear response over a wide dynamic range and is well suited to applications under high ambient brightness. With built-in proximity sensor, LTR-507ALS-WA offers the feature to detect object at a user configurable distance of typical 50cm Gray Card.
