Abstract
An antitheft sensor 5 of the volumentrical and passive type for the passenger compartment of motor vehicles comprises a Fresnel lens 8 to concentrate the detection radiation on a respective sensitive pyroelectric element 7. The sensor 5 lends itself to fitting standard on motor vehicles and is distinguished by low energy consumption. <IMAGE>
