I'd like to use Arduino to switch on and off a florescent light and an accompanying fan that run on AC.
My idea is to have both the fan and the light plug into a box which is plugged into the wall. Inside the box I'm imagining some sort of switch that gets flips by Arduino. This isn't something that will be switching quickly and repeatedly, something like once or twice a day.
From what I can tell, I think I need a solid state relay. Or do mechanical contacts make more sense?
I'm surprised about the price of SSRs. Here's one from Mouser: http://www.mouser.com/ProductDetail/Crydom/CL240A05/?qs=sGAEpiMZZMtHD6BhCPGf2rhtzH9txeZ5eznW42UzTSk%3d
And another that a lot less expensive. http://www.mouser.com/ProductDetail/Omron-Electronics/G3MC-201P-DC5/?qs=sGAEpiMZZMtHD6BhCPGf2pzm%2flBpqtlmx0FfHN0AA%252bg%3d
What's the safest way to set this up?
Is there a forum topic that already covers this or a Web site that details the components needed to this type of AC switching?
