옥외용 LED 조명기구를 위한 인체감지용 멀티센서 모듈 개발

초록

The multi-sensor module is developed by combining both Passive Infrared(PIR) sensor used for human detection, and Microwave(M/W) sensor used for detecting the tiny movement in long distance, in order to make the outdoor LED lighting intelligent. With the optimized design of the PIR sensor reflector as well as adjustment of the angle and direction of PIR and M/W installation, we found suitable detection zone at the outdoor lighting condition. In the experiment, the successful detection rate of PIR is from 81 to 97 percentage for each different ranges except for detection range of 3 to 4 meter where no detection was occurred. The successful detection rate of M/W sensor is over 82 percentages for all detection zones. The outdoor LED lighting can be intelligent by removing the undetectable and poor detection zone by using the multi-sensor module developed in this study.
