Description for the OPT3001

The OPT3001 is a sensor that measures the intensity of visible light. The spectralresponse of the sensor tightly matches the photopic response of the human eye and includessignificant infrared rejection.

The OPT3001 is a single-chip lux meter, measuring the intensity of light as visible bythe human eye. The precision spectral response and strong IR rejection of the device enables theOPT3001 to accurately meter the intensity of light as seen by the human eye regardless of lightsource. The strong IR rejection also aids in maintaining high accuracy when industrial design callsfor mounting the sensor under dark glass for aesthetics. The OPT3001 is designed for systems thatcreate light-based experiences for humans, and an ideal preferred replacement for photodiodes,photoresistors, or other ambient light sensors with less human eye matching and IRrejection.

Measurements can be made from 0.01 lux up to 83k lux without manuallyselecting full-scale ranges by using the built-in, full-scale setting feature. This capabilityallows light measurement over a 23-bit effective dynamic range.

The digital operation is flexible for system integration. Measurements can be eithercontinuous or single-shot. The control and interrupt system features autonomous operation, allowingthe processor to sleep while the sensor searches for appropriate wake-up events to report via theinterrupt pin. The digital output is reported over an I2C- andSMBus-compatible, two-wire serial interface.

The low power consumption and low power-supply voltage capability of the OPT3001 enhancethe battery life of battery-powered systems.
