- Can anyone explain how the vehicle sensors in front of an access gate work?
- Is it some kind of LF emitter/detector arrangement that detects the metal
- of the car? Would I be able to trigger this mechanism by transmitting on a
- certain frequency? (i.e. Ham Radio, etc.)
-
- Thanks for any info!
