Public Lab: Thoughts on Low Cost air quality sensors

08/01/2018· The PurpleAir originally had a PMS1003 particle sensor from Plantower (Product Page) and I believe that the version two (PA-II) uses 2 PMS5003 sensors (Product Page). 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, …
