Abstract(in English) It is very effective to extract human behavior and control building facilities based on the behavior in smart buildings that should provide safe, comfortable and convenient environment with energy saving. We have been doing research on extracting the human behavior with sensor networks using pyroelectric infrared sensors that are very inexpensive and used widely for security and facility control. The sensor networks provide information of human motion but not their quantitative information such as head-counts. We consider counting people existing in each area of buildings with counters placed on their entrances and utilize the pyroelectric infrared sensor for the people counter. The dual element type sensor with Fresnel lens having one or some pairs of detecting areas detects numbers and directions of pedestrians. When the pedestrians are restricted to walk through only a pair of detecting areas by partitions, we have already confirmed its feasibility according to experiment for various passing movements with various temperature difference between the pedestrians and a floor. We are now trying to count people walking through a doorway. The doorway is about one meter width and only one pedestrian can pass through it and the door is open. The sensor can be attached on a ceiling near the doorway not the doorway itself. The sensor has to detect the pedestrians walking in various directions and in a larger area. We propose a method with one sensor having multiple pairs of detection areas and another with multiple sensors having a pair of detection areas. We describe the methods and show some experimental results.
