3 Description
The OPT3001 is a 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 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 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 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 via 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 enhance the
battery life of battery-powered systems.
