The Antlion Detector is a Resistance device detecting approaching objects.
Used in the Victory Mine by Griggs and Sheckley mostly to detect approaching Antlions, the contraption includes three traffic lights connected to a generator. When it detects vibrations, the lights and an alarm activate. The more vibration, the more lights. It is not foolproof, however, as both Gordon Freeman and a group of Vortigaunts set it off.
