Previous UV Monitor Size Comparison

Here’s the older UV Monitor v 1.2. This one used the same GUVA-S12SD UV sensor, but used it to calculate an accumulated UV dose and warn the user when they are about to get to a dose causing sunburn. Primary issue here was inability to control orientation and therefore the indicdent UV level. Pretty much the only way to use it and get accurate results was to attach it to the brim or top of a hat.
