The Boardoza OPT3001 Breakout Board is a compact and highly accurate ambient light sensor solution based on the Texas Instruments OPT3001 digital lux sensor. Designed to closely match the human eye’s response to visible light, the OPT3001 provides precise ambient light measurements while offering strong infrared (IR) rejection for reliable readings under various lighting conditions.
With its wide 0.01 lux to 83,000 lux measurement range and integrated automatic full-scale setting, the sensor delivers a remarkable 23-bit effective dynamic range without requiring manual calibration or gain adjustments. Thanks to its low-power operation, interrupt functionality, and standard I²C-compatible interface, this breakout board is ideal for smart lighting systems, mobile devices, display brightness adjustment, battery-powered electronics, industrial automation, and IoT applications.
