ABSTRACT:
A microwave sensor is provided that transmits microwaves toward a detection area, performs an object detecting operation based on reflected waves from an object being present in the detection area, and outputs an object detection signal based on a result of the abject detecting operation, the microwave sensor being provided with a detecting operation controller for controlling the object detecting operation to be performed intermittently at a predetermined detection cycle, a time setting changer for changing time setting of the detection cycle, and a filter for preventing a signal outside of a frequency region of a signal obtained when detecting a human figure from being included in the object detection signal and from being output,
