2.7Ghz 마이크로웨이브 도플러 모션 센서 -12M
(Microwave Radar Motion Sensor -12M, RCWL-0515)
개요
- 본 제품은 2.7Ghz 마이크로웨이브 도플러 모션 센서 -12M입니다.
- 2.7Ghz 마이크로웨이브 신호를 이용하여 12미터 거리내에서의 사람 움직임을 검출할 수 있습니다.
- PIR 모션센서와 비교하여 좀더 관통력을 가진 센서입니다.

Note: 1: There should be no metal obstruction directly in front of the sensing surface
2: Leave more than 2 cm of space behind the sensor. If the sensitivity is very high, it is recommended to leave a distance of more than 4 cm. The space behind the module should be as small as possible
3: The module and the mounting carrier plane are as parallel as possible
4: The component side of the module is the positive sensing surface, and the negative side is the negative sensing surface
5: Microwave modules cannot be used on a large scale in the same area, otherwise interference will occur, and the distance between individual bodies is preferably greater than 1 meter
