What is Particulate Sensor? | How does it work ...

20211029· 20211029· A PM sensor uses the scattering of light to find the concentration of PM in the given air sample. PM is a good pointer of air quality, hence PM sensor is used to monitor the air quality. How does it work? A PM particulate sensor usually packs a laser module, a fan to control the airflow, a photodiode, and a microprocessor. The fan and …


20210808· Netatmo is actually a weather station with an external t/RH sensor, that also measures air quality by CO2 parameter only. Air Mentor 2s got a more expensive CO2 and t/RH sensors than both Netatmo and uHoo. Temperature and Humidity sensor (SHT30) is both good itself and placed correctly on the bottom of the device with some gap from the mainboard. …

20140224· The CO2 sensor calibration system lacks, directly, technical solvency. The optical sensor measuring CO2 calibrates considering that the lowest CO2 level all around the globe is 400 ppm, regardless of the location. This is incorrect. I made contact NetAtmo staff …


Fijn stof (PM2,5/PM10) | Samen meten aan luchtkwaliteit

Fijn stof wordt vaak afgekort tot PM, wat afkomstig is van de Engelse afkorting voor ''Particulate Matter''. Naast PM10 (fijn stof kleiner dan 10 µm) komt er ook steeds meer aandacht voor PM2,5, fijnstof kleiner dan 2,5 µm. Deeltjes kleiner dan 0,1 µm worden aangeduid als ultra fijnstof (UFP). Lees hier meer over ultra fijn stof. Gezondheidseffecten. Blootstelling aan fijn stof leidt volgens ...
