Teyleten Robot SongHe TCS-34725 TCS34725 RGB Light Color Sensor Colour Recognition Module RGB Color Sensor with IR Filter and White LED for Arduino

I was not able to control the light via code, so I had to connect the LED pin to my micro to control the light. Otherwise, the board(s) work great!

I am creating a project for sampling air quality amidst other things and this sensor works very well. The C02 takes about 15-25 seconds to stabilize and provide readings. I recommend some smoothing but it does seem to work for the tests that i have tried thus far. wide sensing range. The C02 is not calibrated and I wouldn't use it for scientific uses but it does give a good indication of the estimated C02 in the room and is not too far off. You can definitely see if the levels are too high with this.

They seem to work fine for hobby stuff. They vary unit to unit and Iʻm not sure how well it will perform long term. Itʻs an ok Lego for educational purposes.

I want to write some conditional statements, but don't know exactly which pin is my output

So fast Shipping, exellent product
