Overview

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.

Characteristics

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 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.

Power requirement

Power Voltage:4.7~5.3V

Power supply>1W

Supply voltage ripple<20mV

About service life

Service life is the key parameter of laser dust sensor. The laser diode in this sensor has high quality and its service life is up to 8000 hours. If you need real-time data (such as detector), you can use the default configuration that measures at the frequency of 1time per second. On the occasion of real-time demand is not high (such as filter, air quality monitoring, etc.), you can use the discontinuous working method to prolong the service life. For example, you can start the sensor for 30 seconds per minutes.  If you have any other requirements, please contact us, we are willing to serve for manufacturers and developers.
