Hello,
I need to build a remote power switch for a 14VDC 200A system.
Using a remote button, I need to break the current on the remote site.
500 meters of distance is the maximum estimated and I will need on the trasmitter a led that indicates if the connection is established.
Can someone help me?
Parts and schematics/programming… I’m a newbie…
thanks,
Paolo
May I suggest doing a search on Amazon for XBee Relay. You will find that there are already products out there that will do what you want using an Xbee module for little cost.
This is only an example of what I found:
