CAPACITIVE SENSOR SYSTEM FOR PERIMETER PROTECTION DEVICES

摘要

The invention relates to a capacitive sensor system for perimeter protection devices, which system can be easily built into walls and other perimeter protection devices, where it can go unnoticed and remain insulated from adverse weather conditions. For this purpose, the system is formed by two basic elements, namely: a sensor element (1) in the form of a flexible capacitor with reduced thickness but increased length, intended to be camouflaged in the surface of the rigid barrier; and a control electronics module for measuring variations in the capacitance of the sensor element by means of an integrator (13) connected to said element and associated with a microcontroller (12) which records any possible variations. The device can be used to monitor different pressure levels for the sensor, thereby preventing the triggering of false alarms.
