Public Lab: Thoughts on Low Cost air quality sensors

Jan 08, 2018 · The main difference between the 1003 and 5003 is the path that the air follows inside the sensor (which accounts for the difference in size). The electronics inside are the same and they have the same output of PM1, PM2.5, PM10 and particle counts per 100ml of particles larger than 300nm, 500nm, 1micron, 2.5micron, 5micrion and 10micron.
