This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can do an analog to voltage conversion then you can detect the level of UV.

UV is important to reptiles (and people) in processing vitamin D3 which is needed to absorb calcium. Without it reptiles often suffer from Metabolic Bone Disease (MBD) which leads to weak bones and can be fatal. Thankfully, pet shops have the answer, UV producing globes which can stave off the dreaded MBD. These are in the form of T8 florescent tubes or compact florescent globes and go for $50+ each. And, yeah, they need to be re...
