节约能源的低功耗占有传感器

Low-Cost Occupancy Sensor Saves Energy

本文介绍了一种称作占有传感器的控制装置。占有传感器根据所探测到的空间是否被占有来决定灯的通断。在某些场合可以降低照明用电损耗40%或更多。占有传感器采用三种基本技术:红外技术、超声波技术和声敏技术。

In this paper, the author introduced a control device named occupancy sensor. Occupancy sensors detect the presence or absence of people and turn lights on and off accordingly. They may reduce lighting consumption by 40 percent or more in some cir- cumstances. There are three basic sensor technologies: infrared, ultrasonic, and acoustic.
