If everything works right the plot you see here is the UVA and UVB levels at my location plotted from midnight local time till the present. The system is currently experimental and uncalibrated and the levels only show the relative UVA and UVB amounts. The red plot is UVB and the blue plot is UVA. The sensor used is a Vishay VEML6075. Plots for past days that have data avaliable can be viewed by selecting a date below.
