PM Sensor SDS011 High Precision Laser PM2.5 Air Quality Detection Sensor Module Super Dust Tester Digital Output
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.
Scope of application:
PM2.5 Detector
Purifier
Air Exchangers
Filtering system
Working principle:
Using laser scattering principle:
Light scattering can be induced when particles go through the detecting area.
The scattered light is transformed into electrical signals and these signals will be amplified and processed.
The number and diameter of particles can be obtained by analysis because the signal waveform has certain relations with the particles diameter.
