    AC volt reading ok, I use 12bit resolution to get accurate readings. Small enough package.

    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.

    Good for isolating AC from Electronics and convert the signal to logic level in one module. Very easy working.
