Abstract

The subject matter of the invention is a pressure-sensing device settled onto or under ground level. The device has a surface large enough for a human being stepping onto and contains an electric switch can be connected to an alarm system as a sensor. The pressure sensing devices can be connected to each other to form a large dimension sensor. Field of usage: police, military and border guard. Camouflage is advantageous e.g: placing under a mat or under a layer of soil.
