A really sophisticated and accurate colour and luminance sensor breakout that's Raspberry Pi and Arduino-compatible. As well as detecting RGB colour and light level, it has added bells and whistles like 50/60Hz light noise rejection, a wide detection range, and two illumination LEDs.
This type of sensor is the same as you'd find in phones, tablets, and laptops where they're used to detect ambient light temperature and adjust the colour temperature of the display accordingly.
The BH1745 Luminance and Colour Sensor Breakout has an I2C interface and is 3.3V or 5V compatible. Like our other Pimoroni breakouts, we've designed it so that you can solder a piece of right-angle header onto it and then pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 6, 9).
It's compatible with our fancy Breakout Garden HAT, where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code.
We've put together a Python library that you can use to read data from your BH1745 Luminance and Colour Sensor Breakout, and an easy one-line installer to install everything.
You can also use this breakout with Raspberry Pi Pico and other RP2040 boards, using C++ or Pirate brand MicroPython.
