Re: ignition detection

hi
just take that wire from the car (there is a ignition wire)
and connect it to a MCU input.
(ofcourse you will need a protection circuit for the input and the mcu)
also use TVS diode.

good luck.

Re: ignition detection

Most new vehicles have an On Board Diagnostics OBD and you can get the ignition signal directly from there.
