BH1745 Luminance and Colour Sensor Breakout
A sophisticated and accurate colour and luminance sensor breakout from Pimoroni. The BH1745 detects RGB colour and light levels with features like 50/60Hz light noise rejection, a wide detection range, and two built-in illumination LEDs.
This type of sensor is found in phones, tablets, and laptops where it detects ambient light temperature and adjusts display colour accordingly. Designed for easy use with Raspberry Pi—solder the included right-angle header and connect directly to GPIO pins 1, 3, 5, 7, 9. Also compatible with Breakout Garden.
