Ac voltmeter (0-600 volt)

AC VOLT METER USEING PIC 16F676

Herr to measure the mains AC
voltage and the output voltage of the sine wave as well as raw supply.All I
had to do was to convert the mains AC to DC,
filter it and measure the peak voltage. Of course
this had to be scaled down to a safe range for
the microcontroller. The RMS voltage for a sine
wave is equal to 0.707 (to 3 decimal places) the
peak voltage.
The design was based on the Microchip
PIC16F676. The variable resistor is adjusted so that the
reading of my AC voltmeter matches that of a
commercial digital multymeter .
This is a sort of calibration.

CAUTION: THIS CIRCUIT IS NOT ISOLATED
FROM THE MAINS AC AND HAS THE
POTENTIAL TO BE LETHAL. YOU MUST BE
VERY CAREFUL IF YOU ARE GOING TO USE
THIS DESIGN. DO NOT ATTEMPT IF
INEXPERIENCED. I CANNOT AND WILL NOT BE
HELD RESPONSIBLE FOR ANY DAMAGE DONE
WHILE USING THIS CIRCUIT.

  8. Dear sir,
    I need hex bin file for AC voltmeter from 0 to 600 volt on PIC16F676. I have universal IC pic programmer. I try to make AC voltmeter it myself. I am newly electronics technical person. If possible give me the schematics for that. I will be happy for your help. Thanks "Hamid" oppof1shamid@gmail.com
