Line Sensor

device code a2013

We're indirectly measuring the ac line voltage through a 12 volt ac wall transformer, a resistive voltage divider, half-wave rectifier and rc filter with time constant of about 1 second. <a href=http://c2.com/cybords/wiki.cgi?PowerAnalysis>(more)</a>

Try plotting this with D3 Line.
