Impact sensor

Impact sensors detect when they are accelerated beyond their set limit. They were initially added for the Weapon DLC to serve as triggers for warheads. Note that they are no longer strictly required for that purpose since, as of V1.3.14, warheads have been modified to have built-in impact sensing capability.
== Uses ==
* Autonomous vehicle damage detection: Unmanned tanker ships making trips to the arctic may run into moving icebergs. Such ships should normally have very low acceleration, but an iceberg collision could easily set off an impact sensor, allowing it to trigger a distress signal and get a player to fix it.
* Complex warhead triggers: Some missile designs are intended to have multiple sensors to trigger them (e.g. impact or proximity), and sometimes several conditions to prevent activation (e.g. proximity to friendly vehicles) especially with long-range effects like EMP warheads). For these, a microcontroller may combine data from radar, an impact sensor, and radio to trigger a 0-threshold warhead only when it is appropriate to do so.
