Typical Ignition Detection
IGN (Pin3) is used for ignition detection. It is strongly recommended to connect this pin to
ignition key “RUN” position as shown above.
An alternative to connecting 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 start transmitting information to the backend server when
ignition is on, and enter the power saving mode when ignition is off.
