Using ACS712 to measure AC (current and voltage) for Noobs

Using Arduino Sensors
#1

I am buying an ACS712. And I want to measure Current and voltage from the mains. My first question is, is it possible to do so without adding any extra circuitry ?

If it is possible, could anybody give a code or an Algorithm to help me achieve it? I am a noob at electronics.

No.

This is a great resource for safe methods to monitor AC power.

#3

i have purchased the ACS712 already . Could you point to a guide that has that?

#4

I assume that you have one of many boards with ACS712, not just a chip on its own ... so :

#5

isnt that for DC current ?

#6

It doesn't matter if it's DC or AC. If measured value is fluctuating too fast, then you can take, for example, 100 samples and average them.

#7

just another thing. What is this calibrating thing? How to I calibrate my module and get a final value in AMPS?

#8

Remind me, where did you tell us what kind of board do you have ?
