OPT4048 Tri-Stimulus Color, Light Temperature and Lux Sensor is a modern take on the common 'RGB' color sensor: this time with true "CIE" output so you can match it to your existing color space. It's also excellent for calculating color temperature, which is based on CIE, and as a bonus also has Lux calculation, up to 144 kLux for light measurement even in the brightest situations. The OPT4048 has a lot of configurability, with the ability to adjust the integration time (how long light is being measured) to set the sensitivity of your measurements depending on the lighting conditions, from 600 s for ultra-bright to 800 ms-per-channel in dim situations. There's also an interrupt for low/high threshold. To make the sensor easy to use, we've taken the OPT4048 and put it onto a breakout PCB along with support circuitry to let you use this little wonder with 3.3V (/for ) or 5V (for / Metro328) logic levels. Additionally since it speaks I2C you can easily connect it up with two wires (plus power and ground!). We've even included qwiic compatible for STEMMA QT connectors for the I2C bus so you don't even need to solder!
