日本富士通赛内拉尔公司最近生产出两种新型传感器—红外线人体检测传感器和超声波人体险测传感器。 红外线人体检测传感器是通过接受人体发出的微弱的红外线,使原有稳定的红外线发生变化进行检测的,因此最适用于检测移动的人体或功物等。该传感器灵敏度高,可以移动,能检测距离5m的人体或功物,而且视角使用特殊的透 Japan’s Fujitsu-Saineral company recently produced two new sensors - infrared body detection sensors and ultrasonic body detection sensors. Infrared human body detection sensor through the body to accept the weak infrared, so that the original changes in the stability of the detection of infrared, so the most suitable for the detection of moving human or utility and so on. The sensor has high sensitivity and can be moved to detect the human body or object at a distance of 5m, and the viewing angle uses a special through
