PM2.5 refers to particles with a diameter of 2.5 micrometers or smaller, while PM10 refers to particles 10 micrometers or smaller. Sensors are often calibrated to detect both simultaneously.
Particle and Dust Sensors Component Intelligence
Precision optical and laser-based sensors for real-time particulate matter detection.
What are Particle and Dust Sensors components?
Particle and dust sensors utilize laser scattering or infrared LED technology to detect particulate matter (PM2.5, PM10). Selection depends on required accuracy, sampling frequency, and the specific communication interface (UART, I2C, or PWM) needed for your host controller.
How to Choose Particle and Dust Sensors Components
Selecting the right sensor requires balancing detection accuracy with environmental constraints.
Detection Technology
Choose laser scattering for high-precision PM2.5/PM10 monitoring; use LED-based sensors for cost-sensitive, general-purpose dust detection.
Interface Requirements
Verify if your MCU supports the sensor's output protocol (UART, I2C, or PWM) and ensure voltage compatibility.
Environmental Robustness
Consider the operating temperature and humidity range, as condensation can significantly degrade optical sensor accuracy.
Sampling Frequency
Determine if the application requires continuous monitoring or intermittent sampling to conserve power.
Calibration Needs
Check if the sensor provides factory calibration or requires periodic field recalibration to maintain long-term accuracy.
