How to design PM2.5 sensor with accurate measurement and high sensitivity

Update: 2019-09-06 15:44 Source: LUFTMY Reading: ↻ News
 

In recent years, the haze weather has caused adverse effects on people's life and health, so the research on particulate matter detection technology is urgent. The core technology for detecting particle concentration is to design an accurate and reliable dust concentration sensor. Compared with China, the research on dust sensor started earlier and the technology is more mature abroad. The sensor has been widely used in military, aerospace, industrial control and detection technology and other fields.

If according to the basic principle of photoelectric sensor, using the mature technology of correlation detection mode, high brightness, high sensitivity, good stability of laser source as a light source, with the gain and the I/V voltage, voltage amplification, follow a modulation circuit optimization and innovation, realize the accurate detection of the particle sensor, and through the experiment to prove that the sensor has simple structure, stable and reliable performance, accurate measurement, high sensitivity.
