Boardoza OPT4048DTSR Ambient Light and Color Sensor Breakout Board
Boardoza OPT4048 Color Sensor Board is a high-precision optical sensing solution designed for advanced ambient light and color measurement applications. Based on the OPT4048, the board supports high-resolution color measurement in CIE color space, correlated color temperature (CCT) calculation, and accurate ambient lux sensing.
The sensor features high infrared rejection, allowing reliable measurements even behind dark optical windows where IR leakage commonly affects conventional light sensors. With automatic full-scale range detection and a 26-bit dynamic measurement architecture, the device can accurately measure very low and very high light levels without manual calibration or range switching. The board supports continuous and one-shot measurement modes, programmable interrupt generation, threshold detection, CRC protected output registers, and integrated sample counters for reliable data acquisition in embedded and industrial systems.
Its high-speed I2C interface, low-noise optical front-end, and configurable conversion timing make it suitable for smart lighting, display brightness control, camera white balance systems, environmental monitoring, medical devices, and industrial optical sensing applications.
