Description

LTR-91400is an integrated low voltage I2C ambient light
sensor [ALS], gesture sensor [GS] 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 ** capable of direct I2C interface. The gesture sensor provides 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 linear response 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 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-sensor variations for ease of manufacturability to the end customers.
