Hey all,
Working on a project at the moment and could use a little inspiration.
I have a rail on a PCB that normally sits at 4V. When an event happens the same rail drops to 0.9 - 1V for about 10 seconds until the event ceases and the rail returns to 4V. I need a way to trigger a relay "on" when the rail is at approx 1V and trigger "off" when it is at 4V.
Any ideas?

Why not get a 4V SPDT relay? Just connect the output to the commonly off pin. Most cheap relays will trigger at 4V and not 1V

voltage and amperage are two different things if you are a little ways away from where you are drawing your voltage than you are probably loosing amperage imagine a water line the further you get away from the source the less volume you have (amperage) but the closer you get to where you release it the more volume (amperage) you have but you still have the same pressure (voltage) throughout the line
