光宝 LTR-91400

ltr-91400 isan integrated low voltagei2c ambient light
sensor [als], gesture sensor [gs] and proximity sensor [ps], with built-in emitter in a single miniature chipledlead-free surface mount package.
this sensor converts light intensity to a digital output signal capable of direct i2c interface. the gesture sensorprovides object motion direction information based on the reflected ir light detected by the 4 photodiodes for east, west, north and south direction. besides, ambient light sensor provides a linearresponse over a wide dynamic range and is well suited to applications under high ambient brightness. with built-in proximity sensor (emitter and detector), it offers the feature to detect object at auser configurable distance.
the sensor supports an interrupt feature that removes the need to poll the sensor for a reading which improves systemefficiency. 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 minimalsensor-to-sensor variations for ease of manufacturability to the end customers.
application
