{"product_id":"bh1745-luminance-and-colour-sensor-breakout","title":"BH1745 Luminance and Colour Sensor Breakout","description":"\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eThe BH1745 Luminance and Colour Sensor Breakout has an I2C interface and is 3.3V or 5V compatible.
