I'm looking to switch on an indicator light, until reset by a manual switch when a voltage drop occurs. the circuit is typically 3.6-4.5V (DC) when this voltage drops to 0.7-1.4V (DC) I want it to trigger a LED indicator so we know this trigger has occurred. Even after all power has been removed from the circuit.
Basically it is a lean angle sensor on a piece of equipment that will be turned off and lose all power. I need a way to track if the machine has been tilted past this sensor.
What is the solution to this? thanks in advance
