Transformer-less AC Voltage Measurement.

00:50:47

Sometimes in circuits you have to measure AC voltages. But using a transformer makes things bulky. There should be some transformer less method to measure voltage. I will give a method through which measurement will become so easy, less bulky and without transformer.  440V RMS maximum input. Output between 0 and 5 volts centered at 2.5 volts and can be used in a microcontroller like Arduino. Reduces line voltage  by 300.
