Abstract:
A sensing device comprising:means for acquiring a feature quantity representing a physical state to be sensed,a feature quantity display device, which includes a plurality of first indicator elements arranged in a line, for indicating the feature quantity acquired by said feature quantity acquiring means by a bar graph expressed by said first indicator elements;a threshold display device, which includes a plurality of second indicator elements arranged in correspondence with the first indicator elements of said feature quantity display device, for displaying a set threshold value in correlation with the bar graph;judging means for comparing the feature quantity acquired by said feature quantity acquiring means with the threshold value and for outputting a comparison result;means for changing the threshold value in a plurality of discrete points in correlation with the second indicator elements in said threshold display device as the acquired feature quantity is being compared with the threshold value by said judging means; andmeans for holding the threshold value changed by said threshold changing means,wherein said threshold display device indicates the threshold value held by said threshold holding means, and said judging means uses the threshold value held by said threshold holding means in making the comparison with the feature quantity.
