Nova Fitness SDS011 Fine Dust Sensor

Overview:

Using the scattering principle, it can measure the particles in the air with size from 0.3 to 10 microns.
With digital output and built-in fan

Features:

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

Application:

PM2.5 test
air purifier
air exchanger
filter system

Working principle:

According to the scattering principle:
Light scattering is caused when particles pass the detection area.
Scattered light is converted into electrical signals that are amplified and processed.
Since the signal waveform and particle size have a certain relationship, the number of particles and their diameters can be analyzed.

Technical parameters:
