미세먼지 센서 -PM2.5 먼지 센서, 공기품질 체크
(Air Quality Sensor - PM2.5 Dust Sensor, SDS011)
개요
- 본 제품은 미세먼지 센서입니다.
- 레이져 산란 효과를 이용하여 PM2.5 및 PM10 등급의 미세먼지를 측정할 수 있습니다.
- UART 인터페이스를 가지고 있어 쉽게 다른 장치와 연결이 가능합니다.
- 알림: 생산과정중 제품 외관에 기스 등의 스크래치가 있을 수 있사오니, 구매전 참고 부탁 드립니다.
특징
- 1. Accurate and Reliable: laser detection, stable, good consistency;
2. Quick response: response time is less than 10 seconds when the scene changes;
3. Easy integration: UART output (or IO output can be customized), fan built-in;
4. High resolution: resolution of 0.3ug/m3. - Technical Parameters:
