Plume Labs - Flow 2

General Description

The Plume Labs Flow 2 is a wearable air quality sensor that provides real-time measurements of particulate matter (PM1.0, PM2.5 and PM­10) mass concentrations, VOC and NO2 concentrations. Data can be visualized and exported using the phone application for Android and iPhone via Bluetooth.

Principle of Operation

The Plume Labs Flow 2 sensor uses a laser particle counter to measure particulate matter mass concentrations through light scattering and a heated metal oxide sensor to measure gases.
