1. Description
The LTR-579ALS-01 is an integrated low voltage I2C ambient light sensor (ALS), and a proximity sensor (PS), with built-in emitter in a single miniature chipled lead-free surface mount package.
The ALS provides a linear response over a wide dynamic range, which is well suited to applications under very low or bright ambient brightness. Besides, with built-in proximity sensor, this sensor offers the feature to detect object at a user configurable distance.
The sensor has a programmable interrupt with hysteresis to response to events and that removes the need to poll the sensor for a reading which improves system efficiency. This CMOS design and factory-set one time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability to the end customers.
