The OPT3001-Q1 is an optical sensor
that measures the intensity of visible light. The spectral response of the sensor
tightly matches the photopic response of the human eye and includes significant
infrared rejection, and over a wide angle of incidence for the SOT-5X3 package
variant.
The OPT3001-Q1 is a single-chip lux
meter, measuring the intensity of light as visible by the human eye. The precision
spectral response and strong IR rejection of the device enables the OPT3001-Q1
device to accurately measure the intensity of light as seen by the human eye,
regardless of light source. The strong IR rejection also aids in maintaining high
accuracy when industrial design calls for mounting the sensor under dark glass for
aesthetics. The OPT3001-Q1 device is designed for systems that create light-based
experiences for humans, and an ideal preferred replacement for photodiodes,
photoresistors, or other ambient light sensors with less human eye matching and IR
rejection.
The digital operation is flexible for
system integration. Measurements can be either continuous or single-shot. The
control and interrupt system features autonomous operation, allowing the processor
to sleep while the sensor searches for appropriate wake-up events to report through
the interrupt pin. The digital output is reported over an I2C- and
SMBus-compatible, two-wire serial interface.
The low-power consumption and
low-power supply voltage capability of the OPT3001-Q1 device enhance the battery
life of battery-powered systems.
Measurements can be made from 0.01lux
up to 83klux, without manually selecting full-scale ranges, by using the built-in,
full-scale setting feature. This capability allows light measurement over a 23-bit
effective dynamic range.
