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.

Ottimo per isolare l'AC dall'elettronica e convertire il segnale a livello logico in un unico modulo.

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