IGN (Pin4) is used for ignition detection. It is recommended to connect this pin to
the “RUN” position
of the vehicle ignition switch as shown below.
An alternative to connect to the ignition switch is to find a non-permanent power source that is only
available when the vehicle is running. For example, the power source for the FM radio.
IGN signal can be configured to transmit information to the backend server when ignition is on and
enter power saving mode when ignition is off
