The C-SHIELD project focuses on the development of an innovative system dedicated to the detection of chemical hazards. Built upon proven concepts and prototypes, C-SHIELD provides a system for chemical point detection and identification with the use of heterogeneous sensor nodes. The solution is based on two different detection technologies, namely Ion Mobility Spectroscopy (IMS) and Flame Photometric Detection (FPD). These two technologies are combined via a small hardware unit called a node. This physical device is equipped with a dedicated data fusion software, which combines and processes the sensors signals. The applied data processing algorithms will help reduce false alarms as well as estimate the class and ID of the detected substance. This will, ultimately, increase the situational awareness of the end-users in the area of interest.
