Project - House Automatization - Help with current sensor programing

Hi everyone.

I'm from Brazil, and I developing a project for home automatization. This almost done, only need a programming model for this voltage meter:

can you please provide me a programming model of ARDUINO to check whether there is current in the wire?

Tank you

wow thats asking just to do all the work for you.

I have also asked questions in this forum, but I always try to put all my information and work in advance.

You say your project is almost done, so I guess you have very good Arduino experience. Im sure you can try to put some code lines together and paste them here. This website has all you need. search

I' m sorry about that.

I know that asking without search or something its not the correct posture. I do this because my english it's very bad, and it's very hard to get those kind of information in my country.

I'll try to be more specific.

The project its a home automatization controlled by arduino and Asterisk. The asterisk receive and interprets de DTMF singnal (comands to turn ON/OFF or open/close) after the user sends the comand, Asterisk provides an audio message "the room light it's ON" or something. So , before I turn ON or OFF the light's, or open/close the gate,i need to know they status (ON/OFF open/close).

For this project is using the following:

- An Arduino MEGA 2560:

- A 16 relay board

- 16 current sensor (I accept sugentions to know if the gate it's open/close, thoses it's only to know if the light or the appliances it's ON)

So i really need help for the programing Arduino to know the status of the wire in the current sensor.

Tank You

Get a data sheet for your sensor. You can do nothing without one.

Then, if it is a current transformer, look at http://openenergymonitor.org/emon/buildingblocks/ct-sensors-introduction and http://openenergymonitor.org/emon/buildingblocks/ct-sensors-introduction You can get ideas for the code from the sketch Arduino sketch - currently only.

do you want to know if something is ON/OFF? or how much power is using?

- 16 current sensor (I accept sugentions to know if the gate it's open/close, thoses it's only to know if the light or the appliances it's ON)

each CT reading takes around 200milliseconds, if i remember correctely, so 16 would mean 4 seconds of arduino doing this each time
