Hi, I posted the latest firmware on the Downloads page. You can tease out the APDS code that I’m using. The trick to get ‘reliable’ lux data is to use the correct gain and integration timing for the amount of light available. I’m taking an initial reading, and then making adjustments. It helped to first run some code that barfed out the lux values for each gain and integration time setting, so I could see how the data was changing given different light conditions. with a range from 0.02 (moonless night) to 10,000 (direct sunlight) it’s important to massage the numbers.

Hello, I saw that you are using an APDS-9301 sensor in your project, were you able to collect meaninfull LUX values from it? I am also using one of these in a project, but it always reports very low values of LUX, for example, a desk lamp pointing directly at it only reads 90Lux, which seems very little. Thanks for your help
