I'm working on a circuit for an automotive application. It will use the voltage output from a manifold absolute pressure sensor to activate a relay and turn on a solenoid. I'm rather new to circuits, so I'm unsure of what diode and resistor to use in the circuit.
I want the V-out to run through a zener diode so that the relay will only activate when the MAP sensor passes enough voltage through the resistor to ovecome the zener voltage of the diode. The input of the MAP sensor/relay side of the circuit is 5v @ 850mA.
