Spectral Response: OPT3001-Q1 and the Human

Eye

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.

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.
