3 Description
The OPT3001-Q1 device 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.
The OPT3001-Q1 device 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 meter 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.
Measurements can be made from 0.01 lux up to 83k
lux, 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.
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.
