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 to the diode. The input of the MAP sensor/relay side of the circuit is 5v @ 850mA.
