Controlling 220V relay with arduino

How to connect a 220 Volt relay with Arduino Uno to control an immersion rod heater??

You need to use 5V or 12 V relay for isolation. See the the link Arduino Playground - HomePage for reference. You need to choose the rating of the relay in terms of AMPs that can handle the load of your immersion rod.

do not double post,

Duplicates merged.

can any of these SSR be used for my purpose???

How can I use an arduino with motion detection in many 220v appliances..?
If there is no one in a room.. motion detection will shut off the appliances... but if i will going to use my phone it will bypass the motion detection and i will going to turn on the appliances I want to open even though I was not there..
plss help me..

Can I ask in what do u intend to put this, I am asking because I am building a small project with 2 relay modules connected to 220v, and I would like to get an idea in what box to put them, and how do u mount,.

Can u give a pic of a box and mounting, or suggest where to look?

sorry to badge in, but I wanted an opinion from people who have it.
