Hello people, newbie here. what I would like to do is and i am a bit confused about is....
close a mosfet relay at point A, have this relay closure (or some sort of digital information) transmitted by blue tooth or some wireless medium (up to a distance of 4-5 K. -line of sight- and at point B have this transmitted signal trigger a similiar mosfet relay... is this technically possible? are there products available that would allow me to do this cheaply?
I thank you in advance for any help anyone can offer.
