This is a breakout board for the APDS-9250 chip from Avago Technologies, a color and ambient light sensor with four independent channels (red, green, blue and infrared). With this RGB+IR sensor you will be able to measure ambient light while reading separated values for green, red, blue and IR.
The APDS-9250 has multiple photodiodes arranged in a matrix placement to achieve optimal angular response, making it a high-sensitivity device that can be used under a wide range of lighting conditions, like behind attenuation materials or dark glass.
The sensor can be accessed through I2C (Arduino Wire for example), and it’s very easy to use. We have prepared a library for Arduino and the related hook-up documentation so you can start measuring with this sensor in no time.
On the board you can also find the optional I2C and interrupt pin pull-up resistors, that can be enabled by convenient solder jumpers on the back of the board.
Use this sensor to make ambient-mood LED light effects (by measuring the color tone of the surroundings and shifting the colors of the LEDs to match the environment) or you can use it to make a marble color sorting machine!
