LTR-303ALS-01 LITEON 光宝 SMD 进口原装 SMD 环境光传感器 Ambient Light Photo Sensor

The LTR-303ALS-01 is a low voltage I2C digital
light sensor [ALS] in a low cost miniature chipled
lead-free surface mount package. This sensor
converts light intensity to a digital output signal
capable of direct I2C interface. It provides a linear
response over a wide dynamic range from 0.01
lux to 64k lux and is well suited to applications
under high ambient brightness. There are
altogether six gain settings (1X, 2X, 4X, 8X, 48X
and 96X) available for user to configure.
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.
