More Information
Summary:A switching system for warning of the presence of an object and/or individual origin close to a determined area of a traffic lane, characterized in that the switching system comprises at least one piezoresistive pressure sensor (11) activated by weight of the object and/or individual origin located near the determined zone of the circulation path, where the piezoresistive pressure sensor (11) comprises a cementitious composite and the piezoresistive pressure sensor (11) is configured to provide a first electrical signal of output as a response to a deformation of the same piezoresistive pressure sensor (11), which is a function of the variation of the electrical resistivity of the cementitious composite, and an evaluating electronic circuit (21) that receives the first electrical output signal and provides as output a warning signal (31) towards the target object and/or individual.
