yes its pretty handy, one thing that caught me out was that the TSL2561 will overload in full sun. It is VERY sensitive. I have found its only great for indoors. It has a range from 0 - 40,000. But full sun can be up to 120,000. So keep it indoors or under a filter of some kind (smoked glass or plexi/acrylic) and watch the graph over a day or two and you can then work out your baselines.
When it overloads it gives a “NAN” value or basically can’t post any data. so don’t panic if you find this (I thought I had a broken sensor).
