Nova Fitness SDS011

product description
Overview:

Using scattering principle, the particles can be obtained in the air 0.3 ~ 10um concentration.
With digital output, built-in fan stable and reliable.

Features:

1, accurate and reliable: stable detection, consistency;
2. Fast response: Response time changes less than 10 seconds;
3.Easy to integrate: UART output (or IO output can be customized), the fan built-in;
4 high resolution: a resolution of 0.3ug / m3.

Application:

PM2.5 test
Purifier
Air exchanger
filtering system

working principle:

Using scattering principle:
Light scattering can be caused when particles pass through the detection area.
Scattered light is converted into electrical signals, which are amplified and processed.
As the signal waveform and particle size have a certain relationship, you can get the number of particles and diameter analysis.
