Pimoroni BH1745 Luminance & Color Sensor Breakout - I2C Interface
The Pimoroni BH1745 Breakout is a high-precision digital color sensor IC designed for ambient light sensing and color temperature measurement. Operating from 2.3V to 3.6V with an I2C interface, it provides 16-bit digital outputs for red, green, and blue (RGB) light, making it ideal for LCD backlight control in embedded systems, Raspberry Pi, Arduino, and other microcontroller platforms.
Features
- High-sensitivity digital color sensor IC with RGB spectral response.
- Wide dynamic range for illuminance from 0.005 lux to 40,000 lux.
- I2C interface with selectable slave addresses (0x38 or 0x39) and support for Fast Mode (400 kHz).
- Integrated 50Hz/60Hz light noise rejection for stable readings under artificial lighting.
- Low-power operation with programmable interrupt and power-down function.

The BH1745NUC digital color sensor utilizes a photodiode array with an IR-cut filter to deliver accurate red, green, and blue (RGB) light intensity measurements, which are converted to 16-bit digital values. This excellent IR-cut characteristic ensures precise color temperature and illuminance data, critical for automatic display backlight adjustment in consumer electronics and industrial lighting control.
Engineered for signal stability, the sensor features a wide dynamic range capable of detecting light intensities from near darkness (0.005 lx) to bright daylight (40,000 lx). Its integrated circuitry rejects 50Hz/60Hz flicker noise common in AC-powered lighting, providing consistent readings. The breakout board includes a cuttable trace for I2C address selection, level shifting for 1.8V logic compatibility, and all necessary passive components for immediate integration.
