But I think you are right in that a relais is safer than a switch.
But i cannot seem to be able to find the relay I want
- 5v (so it can be powered from USB)
- 433 Mhz superheterodyne
Build pc-powerswitch over 433MHz
I don’t have experience with the programmable 433mhz receiver. but an arduino pro mini and a superheterodyne should work.
This relay?: http://www.ebay.com/itm/310566336050
That would probably work, but I would then (as you said) also need a 433MHz receiver ans something to teach/control it with…
I would rather buy a relay with an integrated 433MHz superheterodyne receiver… Problem is that I can only find them in 12V-versions.
So I’m looking for something like this
But then in a 5V version… anyone?
ebay couldn’t fulfill my needs, but this product on aliexpress looks promising.
It looks like it meets all my requirements:
My setup would look something like this:
What do you think, would this work?
You should use a relay.
Do you know that the power switch works with 5v? I don’t know this. The safe way is to set a relay between your receiver and the power button.
No it is a simple transistor switch. By an signal the output is set to 5v.
This looks good.
