PROBLEM TO BE SOLVED: To provide a monitoring sensor, along with a program, capable of accurately determining the presence of a movement of a monitored person existing in a bathroom, even when there is a movement other than the monitored person in the bathroom.SOLUTION: The monitoring sensor 1 includes a Doppler sensor 10 for detecting the movement in the bathroom 70 to output the detected results as a signal S1; a comparison unit 30 for comparing the value of the signal S1 with a threshold for eliminating a disturbance factor caused by the shake of a hot water surface in a bathtub 71 in the bathroom 70; an LPF (low pass filter) 20 for output of a signal S2 by performing a predetermined filter processing to the signal S1; a comparison unit 31 for comparing the value of the signal S2 with a threshold for eliminating a disturbance factor caused by water discharge from a shower 72 in the bathroom 70; and a determiner 50 for determining the presence of a movement of the monitored person existing in the bathroom 70 based on the compared results of the comparison units 30, 31. |
