PM2.5 Laser Dust Sensor (pms3003) เป็นเซนเซอร์ตรวจจับฝุ่น pm2.5 แบบเลเซอร์ โดยที่เซนเซอร์จะใช้พัดลมดูดอากาศเข้าไปในตัวเซนเซอร์ แล้วตรวจจับฝุ่นด้วยแสงเลเซอร์

PMS3003 using laser scattering theory, be able to get in the air suspended particulate matter concentration of 0.3 to 10 microns, and reliable data; built-in fan, digital output, high integration.
