Can be connected directly to Arduino board since it supply 2.5Vdc offset (when powered at 5Vdc).
Caracteristics:
AC input: up to 250VRMS
DC input up to 32Vdc (according to LM358 chip spec)
Here is my test conditions:
Module powered at 5Vdc:
Input: 120VacRMS
Output: up to 1VacRMS max (variable) + 2.5V dc offset
(Output saturation occur at 0.86V)
Module powered at 12Vdc:
Input: 120VacRMS
Output: up to 1.833VacRMS max (variable) + 5.887V dc offset. No saturation
With AD736 chip, it can be used for measuring RMS voltage with Arduino.
