Le capteur de particules fines pour les nuls - Respire

Apr 28, 2016· Le capteur de particules fines Alphasense aspire l’air dans le boitier de manière régulière. Lorsque le rayon laser rencontre les particules dans l’air, il est éparpillé. La lumière ainsi diffractée rebondit sur un miroir convexe et est ensuite captée par un détecteur photosensible et enfin converti en un signal électrique.

Alphasense OPC-N2 — VAQUUMS project website

The Alphasense OPC-N2 is an optical particle counter. According to the manufacturer, the flow correction of this sensor ensures stable readings, even in high dust environments. The OPC-N2 measures particles from micron to 17 micron diameter at a 1 second interval. The OPC-N2 provides both PM readings and real time particle size histograms.

Air Quality Gas Sensor analysis -

Note there there is another variant, the Miscs 4514, able to detect higher NO2 ranges, but the 2714 is the most suitable for Ambient NO2 sensing. Unfortunatelt, the Mics 2714 is not able to detect NO2 below 50ppb (ie an AQI of 50), so that is not so usefull for places with low NO2 concentration (which is quite often the case). Alpha Sense NO2 B43F
