High-precision laser PM2.5 sensor module for air quality detection Description

High-Precision Laser PM2.5 Sensor Module for Air Quality Detection Description
Overview: The SDS011 utilizes the principle of laser scattering and can measure particle concentrations between 0.3 and 10 µm in the air. Thanks to its digital output and integrated fan, it is stable and reliable.
Precise and Reliable: Laser detection, stable, good consistency;
Fast Response: Response time during scene changes under 10 seconds;
Easy Integration: UART output (or I/O output can be customized), integrated fan;
High Resolution: Resolution of 0.3 µg/m³;
Application: PM2.5 detector; Air purifier.
Operating principle:
Laser scattering principle: When particles pass through the detection range, light scattering occurs. The scattered light is converted into electrical signals, which are amplified and processed. The number and diameter of the particles can be determined by analysis, as the signal waveform is related to the particle diameter.
About lifespan:
Lifespan is the most important parameter of the laser dust sensor. The laser diode in this sensor is high-quality and has a lifespan of up to 8000 hours. If you require real-time data (e.g., for a detector), you can use the standard configuration with a measurement frequency of 1 time per second. For low real-time requirements (e.g., for filters, air quality monitoring, etc.), you can use the intermittent operating method to extend the lifespan. You can start the sensor, for example, every minute.
