SDS198 Laser PM100 Sensor

Short Description:

The PM100 sensor, also known as total suspended particulate (TSP) sensor, using principle of laser scattering, can get the particle concentration between 1 to 100μm in the air. The SDS198 with digital output and built-in fan is stable and reliable.

Product Detail

Product Tags


1. Accurate and Reliable: laser detection, stable, goodconsistency;

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 1μg/m3;

5.Certification: products have passed CE/FCC/RoHS certification.

Scope of Application

TSP monitoring; Dust monitoring; Purification monitoring; Environmental monitoring of road, factory, mine, and construction site.

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.
