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.
