the ltr-553als-wa is an integrated low voltage i2c digital light sensor [als] and proximity sensor [ps] with built-inemitter, 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 alinear 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-553als-wa offers the feature to detect object at a user configurable distance.
the sensor supports an interrupt feature that removes the need to poll the sensor for a reading which improves system efficiency.the sensor also supports several features that help to minimize the occurrence of false triggering. this cmos design and factory-set one time trimming capability ensure minimal sensor-to-sensorvariations for ease of manufacturability to the end customers.
