FAQ：

1. What is PM2.5, and why is it important to monitor?  

   PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or smaller, capable of penetrating deep into the respiratory system and even entering the bloodstream. Long-term exposure to high PM2.5 levels increases the risk of respiratory and cardiovascular diseases. Real-time monitoring helps take timely protective measures to ensure public health and improve environmental quality. 

2. Where can this PM2.5 sensor be used?  

   The sensor is suitable for homes, offices, schools, hospitals, malls, airports, subway stations, industrial parks, environmental monitoring stations, and smart city systems—anywhere air quality monitoring is needed. 

3. What is the measurement principle of the PM2.5 sensor?  

   The sensor uses laser scattering technology: a laser beam illuminates particles in the air, and the intensity and quantity of scattered light are analyzed to calculate PM2.5 concentration, offering high sensitivity and accuracy. 

4. What data output formats are supported?  

   The standard version supports RS485 communication with Modbus protocol, compatible with environmental monitoring systems, PLCs, and smart controllers. Other interfaces (e.g., 4-20mA analog output) can be customized based on specific needs. 

5. What are the power requirements? Can it support different voltages?  

   The standard power supply range is DC 12V-24V. Custom power options are available upon request during ordering. 

6. Will high humidity affect the sensor’s performance?  

   The sensor operates reliably in 0-99% RH environments. Its waterproof and dustproof design ensures stability in humid conditions, but for prolonged use in extreme humidity (e.g., continuous mist), a protective cover is recommended to extend lifespan. 

7. How can the PM2.5 sensor be maintained for long-term stability?  

   - Regularly check the sensor housing for dust buildup.  

   - In dusty environments, gently clean the air inlet with clean, dry air every 6 months.  

   - Avoid prolonged exposure to oil fumes or heavy pollution to prevent contamination of the optical path.  

   - Calibrate annually to ensure measurement accuracy. 

8. What is the warranty period, and is technical support provided?  

   We offer a 12-month warranty. During this period, free repairs or replacements are provided for quality issues. Long-term technical support and after-sales services are also available to ensure optimal performance. 

9. Does the sensor support OEM/ODM customization?  

   Yes, we offer OEM (private labeling) and ODM (custom development) services, allowing customization of appearance, functionality, communication protocols, and installation methods to meet client-specific needs and branding requirements.
