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.

  • Interface specification:

    Pin Name explain
    1 CTL Control pin, reserved
    2 1um >0.3 Micron particle concentration, PWM Output
    3 5V 5V power input
    4 25um >2.5 Micron particle concentration, PWM Output
    5 GND GND
    6 R Serial port receiver RX
    7 T Serial port transmission TX
    PS: The pitch of Interface is 2.54mm

    Communication protocol:

    Serial communication protocol: 9600 8N1. (Rate of 9600, data bits 8, parity none, stop bits 1)
    Serial report communication cycle: 1+0.5 seconds
    Data frame (10 bytes): message header + order+ data(6 bytes) + checksum + message trailer

    The number of bytes Name Content
    0 message header AA
    1 order C0
    2 data 1 PM2.5 low byte
    3 data 2 PM2.5 high byte
    4 data 3 PM10 low byte
    5 data 4 PM10 high byte
    6 data 5 0(reserved)
    7 data 6 0(reserved)
    8 checksum checksum
    9 message trailer AB

    Checksum: data 1 + data 2 + ...+ data 6
    PM2.5 data content: PM2.5 (ug/m3) = ((PM2.5 high byte*256 ) + PM2.5 low byte)/10
    PM10 data content: PM10 (ug/m3) = ((PM10 high byte*256 ) + PM10 low byte)/10
