WIRELESS MAT TYPE SENSOR

PROBLEM TO BE SOLVED: To provide a wireless mat type sensor that can contribute to expansion of area where application of pressure can be sensed, and also contribute to prevention against theft.SOLUTION: In a wireless mat type sensor 10, a part of a pressure sense part 11 is formed in a cut shape and a wireless signal transmission part 12 is arranged in the part in the cut shape. The wireless signal transmission part 12 includes shock sensing means of sensing a shock applied to the wireless signal transmission part 12; shock sense time measurement means 28 of measuring a time for which the shock sensing means continues to sense a shock; human sensing and theft determination means 29 of determining whether a person steps on or whether there is a theft based upon the time that the shock sense time measurement means 28 measures; wireless signal transmission means of sending a human sense signal indicating that a person steps on or a theft signal indicating that there is a theft according to at least a determination made by the human sensing and theft determination means 29.
