PM Sensor SDS011 High Precision Laser PM2.5 Air Quality Detection Sensor Module Super Dust Detector Digital Output
Description:
The SDS011 using principle of laser scattering,can get the particle concentration between 0.3 to 10μm in the air. It with digital output and built-in fan is stable and reliable.
Features:
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 0.3μg/m3.
Scope of application
Detector of PM2.5;Purifier.
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.
Technical Parameters
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.
