Abstract
One embodiment is provided with a microwave sensor (1) that sends a plurality of microwaves of different frequencies toward a detection area, then outputs a reflected wave detection signal (S1) indicating whether or not there is a detection target object in the detection area based on respective reflected waves, and outputs information (Vd) of a distance to the detection target object, a distance determination means (102) for determining whether or not the distance to the detection target object is a predetermined distance or greater based on the distance information (Vd), and an alarm signal output control means (104) for performing control such that an alarm signal (Dout1) is outputted only when the distance to the detection target object is the predetermined distance or greater and when the reflected wave detection signal (S1) is indicating a presence of a detection target object.
