3 Description
The OPT3007 is a single-chip lux meter, measuring
the intensity of visible light as seen by the human
eye. The OPT3007 is available in an ultra-small
PicoStar package, so the device fits into tiny spaces.
The OPT3007 has a fixed addressing scheme which
enables the device to operate with only four pins
connected. This enables the PCB designer to create
a bigger opening to the active sensor area.
The precision spectral response of the sensor tightly
matches the photopic response of the human eye.
With strong infrared (IR) rejection, the OPT3007
measures the intensity of light as seen by the human
eye, regardless of the light source. The IR rejection
also aids in maintaining high accuracy when design
requires mounting the sensor under dark glass. The
OPT3007, often in conjunction with backlight ICs or
lighting control systems, creates light-based
experiences for humans, and is a replacement for
photodiodes, photoresistors, or lower-performing
ambient light sensors.
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 singleshot.
The digital output is reported over an I2C- and
SMBus-compatible, two-wire serial interface.
